Cut the mix on the background music please. Even after you lowered the volume I had a hard time separating out your voice. Question: Has anyone come up with a system for generating bar code stickers for cells that could be used to quickly identify a cell and relate it to a database?

@HBPowerwall 6 лет назад

Sorry you didn't like the music really put effort into that part of the video too :( I think many have talked about it but not really come up with a way to truly get it to work

@Markle2k 6 лет назад

It's not simply a matter of taste. It's the fact that I can't hear what you are saying. Choosing music that avoids the frequencies in the speech range would help too. Surely there must be copyright-safe music that has been created to complement voiceovers.

@HBPowerwall 6 лет назад

I’m sure there is and I’ll take advice onboard

@HBPowerwall 6 лет назад

Just tried it on my kids computers and can hear fine - definitely need to look into it more

@jackrodgersjr 5 лет назад

I was considering building my own battery but after watching a few of these videos I realize how little I know about doing it and would better spend my time earning the money to buy one. I do respect those who have learned these skills.

@alasdair4161 6 лет назад

That will give amazing run times. I just did a similar pack, after making my own outboard using a 2hp mariner leg I fitted with a 90v brushed motor (750w) so I wired my pack as 10p20S with some higher voltage mosfet's in my own PWM speed controller. After a whole weekend of use, it still only reaches ~3.4v/cell. Your build is way better than any lead acid options. He could also plug a lipo alarm into the balance port when in use, it will fire off when there's about 20% remaining with liion's..

@HBPowerwall 6 лет назад

My bro is a massive TECH head and will no doubt improve it :)

@issanesheiwat1396 5 лет назад

How is this better than any lead acid option? Why couldn’t he have just used an 80ah lead acid marine battery? I’m only asking because I’d like to learn more about building a battery pack.

@ClaudioHenrique-gy9cx 5 лет назад

I think because acid batterys can't discharge much than the li pack can. Sorry if im not correct and the bad english :) (but acid battery can suply more ah in a shurtly time, for this are used for start the engine of cars)

@rahulpathania78 Год назад

Awesome. Just one advice, never cut the BMS wires, rather flatten up the bunch and tape it in the end. Cutting BMS wires alters the resistance hence, the resistivity in each group of cell while balancing during the charge process.. something not big, but not too small to be ignored. Thanks 👍

@harleypater7317 6 лет назад

1. Given up on fusing for low current (per cell) applications? 2. Cheap balance boards are more trouble then they are worth!! Balance charge or use a balance checker and only charge to 4.05v once your happy the cells are well matched, checking occasionally. 3. 4s is the new 3s Most camping items will run no problems at 16v and run down to 10v. 4. Where did you get the Asus batteries from at a good price? Stored at 3.6 to 3.8v those batteries will outlast time itself.

@HBPowerwall 6 лет назад

Tried to fuse but looked ugly - yes that's my excuse ugly lol but took every step possible to still build a safe battery. Still needs load fuses and waterproof box for it but that'll be in the next video. I agree those BMS cause more issues than they solve but I was TRYING to build this battery as good as possible. 4s is definitely becoming more popular Over time i've saved 100's of laptop battery packs with these cells in them - too good for powerwall use I thought.

I actually just made up my second for a 24v system. I dont even know what they really are rated at, each 12v battery is 150 1.65ah 18650... I got about 20 running hours using it in different variations between charges to 4.10 to 3.5. Got a bit to finish up and we will see how all 300 handle the new 24v 80lb Terrova

@ahaveland 6 лет назад

I think Tesla cells use a plate with holes that are bigger than the positive terminal and line up with them, then a short fuse connects them. With nickel strips on the positive side, you could make a grid that lies *between* the cells and spot weld the fuses to it, or even try a copper plate with large drilled holes. The negative side can be spot welded as normal. Best place to attach the power cables is at the centre of each terminal plate, or at multiple places for really high currents. With the power cables at the corners, the entire 30P current goes through just 2 strips worth of nickel!

@jitendraparit9374 5 лет назад

I am using 11s10p configuration for my BMS project. That means I'm using 11 stacks in series with each stack consisting of 10 cells in parallel. I am in a dilemma if must balance each cell in the pack(individual cell balancing- 2 wires coming out each cell) separately or get a wire out of each stack(2 wires coming out of each stack consisting 10 cells in parallel) to implement passive balancing algorithm, SOC, SOH. Can you give an insight on which one is more preferable?

@MrSnapy1 6 лет назад

Sweet pack! neater than mine I went the fuse wire route. l have ran into a few problems with my 4s packs the high voltage pushes more amps into the motor reducing the AH rating. Tried a few buck convertors to keep a steady 12.5v but they get HOT will try a few more beefier ones or add a tiny pc fan. Before my buck burnt out I was getting 20% or more run time @12.5 vs 14-16 volts. The bright side is it supercharges the trolling motor lol Still it beats a 3s pack which the motor falls flat with much capacity remaining. Just remember to monitor voltage a 4s will easily drop cells below 3 volts if not monitored.

@HBPowerwall 6 лет назад

Next one I build will be fused between the Series packs I think. It's the neatest way I can think of setting it up. Will take out the whole battery but better than nothing. Hope I can make it to the gold coast soon to my brother's house to test it out. But I'm about as good at 'water' as I am at 'mathing'

@Away907 4 года назад

I've made 25s4p pack for the trolling motor using new 3400mah batteries from aliexpress. Also decide not to take risk with built-in BMS and use ISDT charger instead - at least i can get numbers this way. Gave it a try recently. Running on the slowest speed(3kmh) it lasted for 6hrs and 15min, consuming 180w on average. Wattmeter indicated i managed to pull almost 1150whr up to the moment when voltage dropped to 3v/cell. Going faster require about 300-400w and resulted in low voltage warning when battery was less than 25% of capacity. BTW, these motors can take 16.8V, no need for pwm controller. This will kind of push it to the limits. My motor is rated 430w at 12v, according to wattmeter it was pulling 600w+ on 16.8v battery. Running it full throttle reduces the range. I was getting 15km on medium speed and 18km on low speed. Max speed will empty battery in 1.5hrs with about 9-10 miles covered.

The thing that surprises me is the amount of time spent on sorting the cells to an exact capacity using some simple software to calculate which cell goes in which pack. Given the uncertainty on the measurement of your capacity the actual number is not very important, if you round them all up or down to multiples of 50 or 100 you are fine as well and it saves you a lot of time.

I'm thinking my tips are not sharp enough, and the welds are too big. I also was welding the thick nickle, and the batteries are capable of well over 400amps, I have about 20" of 4gauge cable going to it, with 12" of 2ga, going to the relay, it works well down to 9.5v, being 3s lipo, that's where I stop!

Really should have put more effort into adding fuses of some sort - for its application (in a boat) if there is an issue it'll just go overboard. It will also be moved and bumped a lot much like an ebike battery. I've gone out of my way to make sure I'm using the best most balanced cells I have laying around. Time will tell if it was a good or bad call.

was that an actual wall phone ring talk about a sound taking a person back in time almost music to ones ears havent heard that sound in years thanx for the feed as always enjoyed the build

standard iPhone ring lol drove me crazy as I mostly edit with head phones and kept taking the head phones off and picking up my phone lol good enough reason to leave in hehe

@sshutupurface8345 Месяц назад

do you charge the cells in parralell and if so how many at a time what voltage and amps

@twcstransam 6 лет назад

Neat project Pete

@HBPowerwall 6 лет назад

TY Sir ... 10x longer to film and edit than to just make but I love the end result, can't wait to test it on the water

@twcstransam 6 лет назад

The PCM was a good idea. I'm sure it'll be good, curious as to how long it will last you.

@twcstransam 6 лет назад

Is that a battery powered glue gun?

@mertcapkin7263 4 года назад

I have the same Imax charger. Is it correct that the charger basically replaces the BMS while charging but that you don't have anything that protects the battery pack when being used?

@HBPowerwall 4 года назад

Just common sense & the knowledge that if it over discharges i'll have to replace it :}{

@ronaldbizlink1311 4 года назад

Kinda new to this thing so would like your kind advice as I am also doing it for a trolling motor but my target will be bout 200pcs of 18650s. And what is your view on fusing the batteries as opposed to not fusing them?

@HBPowerwall 4 года назад

Well Ebikes don't fuse, its a smaller battery, you're on water if it has an issue over it goes lol

@the3rddecline 5 лет назад

Pete, how much self discharge do you consider okay? Do you check each cells voltage before you store them for 30 days and check again? Some of my BT-C3100 chargers state that a cell is full at everything between 4.15 and 4.20. So I just now sort them by voltage, let them sit and check them again.. but I am unsure what self discharge is okay, if any at all over 30 days.

@HBPowerwall 5 лет назад

30 days less than 0.05 of a volt give or take

@njfulwider5 6 лет назад

Don't you love the short work a Spot welder makes of a huge battery pack!!!

@HBPowerwall 6 лет назад

There is just a few min of cutting up nickel then bam it's done! And looks so dam good lol

@njfulwider5 6 лет назад

I started out only using a Spot welder(or my homemade built spot welders), I am just now getting used to soldering a cell. If I could get away with it, I use a spot welder on everything. Love the work you put in on this. That battery should last a long time!!! Good cells you used also. You Can't beat those NCRs

@HBPowerwall 6 лет назад

Next challenge will be keeping it dry and servicable

@haroldking979 5 лет назад

I assume its been in service for a while now? Any word how long it lasted etc? Keep up the good work :)

@HBPowerwall 5 лет назад

Haven’t tuned it in since too cold lol haven’t even done a load test

@jamest.5001 4 года назад

Also I used the batt hookup, nickel fuse, 100 cells, in a square, with added strip, in a square, 2cells from the edge, with two strips crossing about 3cells between, with another nickel strip across the top. I have a 12g, silicone wire, connected to the double strip areas and another at the very top. For 4 total, since you tested the fuses. I'm curious if you think this will suffice? My system can only pull about 300 amps. And this is one of 3+ banks, so 100 amps peak, it's not perfect, but I have the current coming from 4 locations in the middle of the pack. Not many have videoed actual use of this stuff. Any idea? Thanks

@alba1307 4 года назад

Are the balancing leads the same with the to methods?

@korishan 6 лет назад

Since this is the latest video, I'll ask here. With your spot welder, are the tips spring loaded? If so, do you push them down until the spring bottoms out? I saw another video where they said spot welding is a resistive welding. Pressing too hard actually reduces the amount of resistance and it doesn't weld as good. Maybe you can play around with pressure on the tips to get different results. Perhaps this is why the arm on the device would work better as it was spring loaded, too.

@HBPowerwall 6 лет назад

yes they are spring loaded - found if I played with settings I didn't need to really press down so hard the springs compressed. Found if it sparked I was doing it wrong

@dunukic 4 года назад

Do I need to consider battery cell resistance when building a battery pack out of different recycled old laptop li ion cells?

@HBPowerwall 4 года назад

You should consider and factor that could cause issues.

@genoory5090 11 месяцев назад

I wanna get a 100ah battery built in this configuration for my wilderness systems ATAK 140 kayak that has a small rear hatch and a 12v minn kota 55lb thrust motor. So was that battery heavy?

@mikemcmanus1179 5 лет назад

With the grids he created, I confess I am not following how this 12V 80AH battery is wired in series and parallel. Have not been able to figure it out from his bars on either side. Can someone explain?

@HBPowerwall 5 лет назад

30 cells x 4 in parallel - 4.2v so effectively it's 12v min 16.8v max charge in the thumbnail that shows positive & negative joined on the left and again on the right - on the other side the gap in the middle is bridged join all cells together.. God I hope that explained it enough.

@johnboyle7984 6 лет назад

What run time would you expect from this setup? Also how long would it take to charge this up?

@HBPowerwall 6 лет назад

Not sure as unloaded at max speed it's only 1.2amp draw - bet that changes once a load is added. As for charing it depends on your charger. Bigger chargers would have no issue doing it in 10 hours - my charger will probably take 20-30 hours flat to full

@theshepherd70 6 лет назад

I really need to ask you a question . I am trying to do the same but I was concern about the voltage @ 16.8 full can the motor handle that ? thanks

@HBPowerwall 6 лет назад

the PWM speed controller sorts out the voltage - goo.gl/vqR8pD

@Jopoiato 5 лет назад

Hi, very nice video. How long after you charge each cell separately, you measure the voltage to make sure they were all fine?

@HBPowerwall 5 лет назад

would have been weeks if not months of resting it's a very good test to do when using old cells

@GabeLynx 5 лет назад

Is not the fully charge voltage too high for 12V? I'm starting the same project for a trolling motor of 12V. im finding it hard to find out if the 16.8V will be damaging the device in the end.

@HBPowerwall 5 лет назад

That is the reason for the little black box it's a PWM controller so you can adjust the power

Hi are you putting the Watersnake controller on 5th speed and having full control through PWM.

Been too cold to even test as yet but plan will on high then PWM to fine tune the speed as required or even slightly over volt if the need arises

@masonharrelson 5 лет назад

How long does it take to do a full charge on the Imax B6? I'm building a similar battery 4s20p and was planning on initially balance charging it off my B6 but I'm wondering if theres a faster/ more simple charging method I could use. Thoughts? Great vid. I enjoyed the music. Mastering everything with an Auratone speaker could help the mix a lot. Cheers.

@HBPowerwall 5 лет назад

Haven't had a chance to discharge the battery yet, got very cold here so haven't even done the testing of it yet unfortunately. I have two more videos planned on loads and charging .. shouldn't be a few weeks. Day Job pays more than youtube so have to juggle my time
