From the Corrections Department: The lower 3rd explanation fo the invention of the term battery is apocryphal. Franklin used the term 'battery' to describe an array of connected leyden jars likening them to a battery of artillery.
I am enjoying how comfortable Felix has become after all this time. People got on him about having no personality in the beginning but now, they can't seem to get enough of him! I must say it's a far cry difference from the extreme change the show had a couple years ago when there were several people on the projects and less Ben. Slowly phasing in a new person has been better than suddenly having a bunch of new people. Anyway....I'd love to know what kind of Li-Ion batteries you use for most your projects as you stated...such as the latest Mame portable. I'm trying to make an NES portable and am using a PSOne screen, but the batteries are the death of me and I have been stumped for weeks!
Wait, last video i complained about the laggy intro that has been there for ages, and now there is a modern, fuid new one? did i coincidence? Or did they actually respond with the new one? Whatever it is, i am happy to see the new one come in :)
TheMiniGeek I think i can safely say my internet connection is fine. If you don't believe me, have a look yourself: www.speedtest.net/result/4583900181.png Jokes on you!
There is one pro for Lead Acid that you should have said. Shelf life. A properly maintained lead acid battery can last for many years where as batteries like Lith-Ion have very limited charge/discharge cycles and typically need replaced after a couple of years depending on how often you use it. Lead acid is great for powering out door solar projects as they are easy to charge, store a lot of power and have a long charge cycle life. We use them for our emergency power for our ham radio equipment on mountain tops and in our to go trailer.
***** Dead right. I have an APC UPS system from 2001 that has the ORIGINAL lead acid batteries in it. They are still going strong to this day when the power cuts out. Now if only I could get the monitor to work on Windows 10. Worked on 7. Oh well...
This was a good basic presentation for the most typically used battery tech used today. Although, I would have liked to see mention of Absorbed Glass Mat batteries when you got to lead acid batteries. They are very expensive but are more powerful, can go through more charge/discharge cycles than lead acid batteries before failing, they are sealed so it cannot leak unless the case is ruptured, and do not put off sulfur-dioxide gas when charging.
Sony used the battery on the PSP (or rather the circuit inside the battery pack) to tell the system which state to boot to. For instance service mode. This is what allowed the "Pandora Battery" hack to work, as users were given access to precisely what I just mentioned: The system's service mode.
In airsoft, guns that run on an electric motor to drive an air piston (AEG) most commonly use NIMH batteries. Because of their relative stability, life, and cost. Although some people use LiPo batteries for their high current output. Although those are less common for their tendency to destroy systems that aren't designed to handle that much power in burst. Which requires extra cost of having reinforced gears,motors, and frequently mosfets. As well as their tendency to heat and burn up if used incorrectly or damaged.
Ben, the Roomba battery pack is not a bunch of batteries in parallel. It's 12 sub C cells, all in series - hence the 14.4V (12x 1.2 = 14.4). 3000 mAh is a common capacity for sub C cells.
Small error at 2:55; 'mAh' does not describe the power, it is the current draining capability. For power you need the 'mWh' rating which is actually more useful but is less often labeled. I'm sure Ben knows this and it was just a slip of the tongue, but I thought that I'd point it out.
Another reason for not putting batteries in checked bag and keeping them on your person is the baggage area of the plane is not pressurized so there can be temperature and atmospheric changes which could cause the battery to swell and possibly short internally. Where as in the cabin area it is pressurized to simulate sea level atmospheric pressure and a comfortable constant temperature which batteries can safely survive in. Unless its a Samsung Note 7! :D
The RAYOVAC lantern battery that was opened up at about 5 minutes into the video and was implied was Alkaline is actually Carbon Zinc. RAYOVAC uses this color combination on the battery package for many of their heavy-duty Carbon Zinc batteries. Additionally, RAYOVAC would always include the word "Alkaline" on at least the main panel of the battery if it were Alkaline.
Hi Ben, I am starting to get into electronics thanks you yourself and a number of other RU-vid authors. I was wondering if you had a list for components that you recommend to have on hand for beginners so I am not going out and getting single components for each new project. Thanks, Jason
You can do some tack welds with a couple 18v lithium drill batteries in a pinch. Don't expect to use them again though lol. I think around 1.5v they become unchargable.
The DeWalt 20V Max batteries are actually 18-volt batteries. I'd like to see you build an adapter with a built-in low-voltage cutoff circuit that would allow you to use 20V Max li-ion batteries in 18-volt DeWalt tools.
No love for jell lead acid batteries? They work the same as normal lead acid, but the acid is gelatinized, so no need to worry about leaks, and the battery can be completely sealed.
genial gracias por el comparativo, es muy importante hablar sobre baterías pues actualmente todo componente tiene. espero posteriormente enseñes a hacer circuitos que analicen la temperatura, carga/descarga, etc.. para usar en proyectos propios. muy interesante la explicación de la batería recargable de xbox, me gustaría también analizaras la parte del control de xbox donde llegan tanto la información como la carga de las baterías, e inclusive la parte superior donde se conecta el cable carga y juega del control. saludos y espero sigas así de bien con tu canal...
I've been hoping for an episode dedicated entirely to charging batteries (mainly li-ion or li-po), and tips and tricks on building charging circuits. Almost thought that this was it, but not quite. :)
Ben, is it possible to transform an Li-Po battery pack from "model planes" (don't know the name) into a battery pack for your old notebook that you have laying around? Because I have an old HP Pavilion dv6670 and it's battery went dead. I think it would need a step-up voltage regulator too because it uses 18 volts to power it. I love the show! Cheers from Brazil!
Pesterenan You can connect Li-Pos to a boost converter. Connect the boost converter output (correct voltage) to an old laptop power lead and you are in business. The only catch and this is important. You must have an under voltage shut down. When the Li-Po voltage gets low it must shut off or you will ruin the batteries.
Great! Well thats a really cool project, unfortunately Li-Pos here are really expensive, and on top of that, they can explode if charged incorrectly. But that really is a good idea. Thanks!
Very informative. I know that the xbox 360 controller will run off of double A batteries without a power pack if you just wedge some pennies under the batteries to keep them in place.
there are two types of C for discharge.. Constant and Burst.. Constant - 2A battery & 10C = 20A constant Burst is normally conciderably higher Burst - 2A battery & 30C - 60A burst.. meaning.. your specific battery can safely discharge at a constant of 20A, but can handle short bursts of upto 60A.. remember.. C rating is the amount of Safe discharge.. Discharging anymore than the specified ratings can cause damage to cells, and can lead of explosions and fires.. (i used to race Brushless RC cars, with LiPo batteries)....
new subscriber here after checking out your content today. was drawn to this particular episode because of samsung phone 7 stuff. betcha their design team had done a more careful review of what you talk about at 16:56. but apple has had similar problems in the past too. when it comes to priorities companies put profits ahead of safety protocols, unless the threats of lawsuits gets too large
No, I'm just really curious what kind of stuff HE wants to show us, talk about or help us with. For example he experienced a problem, he solved it and want to tell us how so we can learn from it. Or for example a rant or something. Felix is a cool dude, I think if he had his own segment he would show us some cool interesting stuff!
The Ben Heck Show I would actually love to see a show (or maybe an spin-off) on his computer. Any time I see him programming, I always wonder what his set up is like. I suppose you could have a few minutes to talk about your setup, too, Ben. :)
The Ben Heck Show In my opinion, I feel like a tech series based around Linux usage and just software in total would be a great fit for Felix. He's entertaining, at least to me, and he seems to have a great understanding of the open sourced os distros and programming in general. Also, maybe a short series showing Felix's process of mapping out and creating some of the circuits you've used in the past like the recharge circuit used in the portable MAME^2. That would be really interesting seeing how many of us don't really know what goes into PCB designing and creation. Those are my ideas, take them or leave them lol. Either way love the show, you're the reason I'm into diy projects now and have like 15 rsbpi's around the house doing random stuff like mining running a cloud server with a cluster and an entertainment system. Thank you so much, literally would have never done anything that I've done in the past years without your influence. Sorry, I'm rambling now, I'm done.
cubedude76 The UPS (uninterrupted power supply) is likely one he bought in a store. They're pretty cheap, comparatively speaking. www.amazon.com/s?ie=UTF8&field-keywords=ups&index=blended&link_code=qs&tag=wwwcanoniccom-20
2:05 ERROR! Battery comes from italian ALESSANDRO VOLTA (from which the VOLT). He stacked disks of metal and fabric wet in acid solution and developed the first PILA (stack). (same as the Telephone: was MEUCCI and NOT Bell, the RADIO, was Marconi (which copied Tesla))
Hey if car batteries are like the batteries in a UPS.. then could you build your own UPS out of car batteries and get like an hours of uptime? Could you combine that with a DC to DC converter to more efficiently power a computer? It might even be cool to build it into a desk so that it's hidden.
I collect retro game systems, can you mod or make a battery pack from the Li-Ion batteries that would connect to the old AA ports ( looking for great rechargeable mods for my Nomad and Game Gear with new LCD screens )
8:00 wouldn't something that runs on a fixed voltage internally use less current at a higher input voltage? I'm guessing that the extra power draw was because the leds were connected in such a way that they get the un regulated input voltage since they were significantly brighter with 6 volts going in to the setup.
Hi, maybe You could show how to charge li-ion baterries that need ballansing? How to charge baterries from cell phone with three or four pins? By the way, Your videos are great.
What about the short shelf-live of lithium batteries, knowing that their electrolyte degrades faster than other batteries techs over time and charge cycles ?
HEI Ben, thanks for all your hård work , kan you help os that has a 1 generation Cube 3d printer, to print with spole filament insted og original cartegis?
The Ben Heck Show How about sharing the charging circuit you use for LiPo batteries? I've been watching for some time, and have seen you make your own but you never share any information about it. I am looking for something that both powers your device as well as charging the battery, then will run the device from battery power when the charger is unplugged. I've found many specialized IC's in BGA or other non-hobbyist packages, or they are dedicated chargers. It would be nice to know what kind of solution you came up with!
***** I know they make rechargeable batteries, but I wasn't talking about those, I was talking about Li-Pol or Li-Ion rechargeable AA and AAA batteries.
i found a battery that is supposed to produce 12 volts and run a portable screen but the screen will not work right when i plug it in it works fine using a 12 volt wall wort though
I remember taking apart a xbox battery pack before looks like it a had a temp probe thingy hanging on it I didn't see that on yours so it stopped charging when it got too hot so I removed that and they charged fully instead of five minute charge only lasting ten minutes without the charge cord
I still remember how someone left a lead-acid battery connected to the charger over the weekend in our confined robotics lab, obviously, it exploded, and the smell was DELIGHTFUL... /s
דוד שלמייב quick-charger?... normally lead-acid batteries don't explode unless something very bad is done with them (such as excessive charging voltage while having them next to an open flame or similar). well, unless it is a flooded lead-acid (vs a VRLA / AGM battery), which tend to leak a bit more hydrogen.
דוד שלמייב yeah. I have mostly ended up charging batteries with a lab-supply, mostly for sake of control over voltages and current. I have an automatic charger, which seems to like spiking to around 17 volts, which is a bit out-of-spec for the batteries I use. I tend to do charging at 14.8 and then drop to 13.6 when the battery is mostly charged. the opposite end is a UPS which seems to always trickle-charge (so takes very long time to charge a battery and generally never goes over 14v). granted, most of the batteries I use are the smaller / UPS-style batteries (mostly sufficient for a lot of the stuff I am doing). plenty sufficient for small robots.

Two more modern things you should mention LiFePO4 and super-capacitors.
I would like Ben's take on these Alkaline chargers I keep seeing about....They apparently recharge/top up standard alkaline batteries up to 3 or 4 times? anybody else feel free to comment...:)
HDose Yes, you can charge them with a very low current trickle charger (there are ones specifically made for this) but you'd still be better off with eneloops.
I have a cable which converts mains AC to 12v DC. How many 9v batteries would I need to put in parallel to produce a current which is the same as the 12v DC?
Ross RS Depends on the current supply of the cable. 12v doesn't mean you have X current, it just means you have 12 volts. That's why power supplies are typically measured in Volts, Amperes (Amps, current) and Watts (total power)
John Wiggins yeah. I guess they are basically like LiON, but better behaved and less explosive, with less energy density but more power density (lower capacity but more amperage). price seems similar to LiON cells. seem to use same cell-type numbers/sizes as LiON as well...
John Wiggins If you really want to look at different types of lithium cells you want to check the torch guys or vapers. Lots of pretty graphs to look at.
Witold Witkowski most 9v batteries I have looked into have a stack of small rectangular cells, typically surrounded by a layer of plastic. IIRC, one had separate cells as individual units stacked together (similar to rectangular coin-cells). more common seems to be alternating layers of plate and electrolyte, with a shared shrink-tube style exterior. though, this is alkaline, no idea about NiMH.
What brand were those? I would think the cheaper ones would be those stacks vs individual cells but I don't have any experience, I just remember seeing they were quad A not triple A.
***** I forget now what the stacked coin-cell one was. one I looked into recently was a "Bateria Prima" battery, which was using the shrink-wrapped tube of plates construction. also have some "PakKo" batteries and similar.
I can't remember which channel as it's been a while but they tore some apart, I seem to remember the name brands being in AAAA package instead of open in plates. But I could be mistaken.
I really thought that the Li-Ion batteries were safer, because I heard that the Nickel ones were more likely to explode that Li-Ion... My whole life is a lie :(
Nahir Sanchez yeah. vs LiON, the nickel-based batteries are pretty stable. also they can be run completely flat and they don't care. had a NiCad battery pack I have been using (3.6v), that I had got ahold of second-hand about a decade ago. so, about a decade of sitting around in a box. charged it up, and it works fine. though, the first time I charged it up (after a decade in a box), it seemed to go dead again pretty fast. after this (charging it again), it seems to go pretty strong. though, I am mostly using it for testing boards (providing logic-rail voltage and/or for providing control signals). this is partly because a lot of my boards use multiple voltage rails, typically 3.3v or 5v for logic, and one or more higher-voltage rails (12v or higher) for driving loads.
