*Works great my **Latest.Bike** I have a bad knee so I still get exercise but the bike assists me. I am a big guy so I didn’t think it would go as fast but it works great.*
So jealous of you guys in the states, haven't found any recycling places that sell packs this cheap or anything close in UK/EU. Man these are such good deals.
If you want decent cells, just buy lishen or BAK 18650, for around 1 - 1.5 dolars a unit. Don´t forget the shipping option is by train to be the cheapeast possible to the EU.
@@brenolima7520 São células de 2500mAh 10A provavelmente, então vc terá que comparar com as mesmas especificações e verá que na lifeion tem quase o dobro de capacidade 4.5Ah ate 5Ah com 10A ou 2C de descarga e o custo é de 25 reais cada or $4,5 each cell. Hoje em dia as 21700 compensa mais do que as 18650.
Some lawn mowers also run on 36V. The pack in my mower is 36V nominal 7.5Ah. Almost does the complete 700m section on a good day. Connectors are Anderson, so could be used as an extra pack.
When you said it was 10s I was thinking no way it can be 7500mAh....maybe 5000 when new at best.....but then you opened her up and my assumption of 2 rows of ten was WRONG .....3 rows of ten in a 2 row config!!!! Nice :)
Just tore one of these down, the BMS is screwed in under the silicone aswell as spot welded in 7 places atleast, a cutting wheel will do but i used a sharp flat head screwdriver like chisel to peel the welds back and peel em off the cells, some where at 0.6v only 6 of 30 the rest where 2v around, ALL recovered and restored
Did you reuse the BMS? I just tore one pack down. 1st time figured good one to learn with. If you tore the cells out of the plastic casing how did you go about it?
@@Sk8strings No i couldnt get it off without breaking the PCB, its well glued down so ihad to pry it off after removing the nickel strips, ive made these into 3s (12v) drone batteries with a spot welder and clamping my cables in a rolled up excess piece of nickel strip, there in battery holders below the two plastic frames i think it was, used a flathead screwdriver and sideways torque for the whole thing
Could you talk a little bit about the process involved in battery recyclers and how they decide what gets recycled vs redirected to the used market? Are companies like bird lime, etc actually paying recycling places to take these packs and then they are selling them back to the market ? Seems like there is the possibility of some shady dealings. Just wondering if you are able to explain the market in a video, it might be a good chance to attract new viewers.
Absolutely. recyclers will get paid to take these cells off a corporations books so they dont have to hassle with the regulatory fees of disposing of this stuff 'properly'. Its up the recyclers to break these down and separate the wheat from the chaff,. It's a win/win for the recycler, they get paid to take batteries (free inventory) as well as make a buck on the back end, Most of the recyclers are middlemen that will then sell to an offshore scrapper who disposes of this stuff in less than US EPS standards... "Not in my backyard" .
Jehu, in an earlier video you created a pcb for flat Pouch cells, the high powered ones. I would like to do similar to reuse some pouch Mac cells, but can’t work out how to do a square pcb cutout, through-holed to put the cell tabs through to solder them into the pack. Could you think about demoing that in a future pcb video?
lol i seriously cant ever buy anything here from the site, every time as soon as i want to buy something and research what ill need for the specific battery everything is always sold out lol
I have an lfaster 36v conversion kit and I am using the 36 volt battery on your site the problem I'm having is that the bike keeps cutting off and I think it's a overheating problem is this because of the voltage on the battery when fully charge the battery has 41 V
these RC batteries are they rewrapped from batteries like that where do these RC controlled batteries come from the big ones especially the 6s they're not manufactured by the label they're manufactured someplace else...... where can I get good lithium-ion batteries and what's the difference between 15r and 25 are
How exactly is this a "good deal" for 30 generic Chinese 2.5Ah cells for $29? That's like a buck a cell +shipping, for used CHINESE cells! OK I guess, but not even particularly "good." Certainly not when BCH sells similarly configured 30 cell packs, but with 3200mAh LGMH1 or panasonic's 18650BD, (10a cdr capable cells) for $23. Plenty great deals around, no need to pity missing out on something that wasn't actually THAT great of a deal in the first place.
@@ABritInNY True, had they been an brand name cell I would have been disappointed, I watched the video for about 10 seconds before hearing if they were a brand name cell to see the sold out sign and thought, "Wow that was quick". On to the next. Yes the BCH MH1 packs are probably the best right now
Hi, Jehu how are you today? I need you to recommend me with which of the batteries you have for sale I can build a 52v battery pack for a very small ev conversion (for an old Fiat 600 from 1962) the motor is 48v 7kw. I started this conversion a year ago, watching your videos. I made a 100amp 52v battery pack from recycled 18650 but I think it’s not enough. Thank you very much!
I have the SW2.. it does fine if you use it within it's capacity. Unfortunately if you need .03mm it will probably not work with pure nickel strip. Plated will work but you are better off using.02mm pure. If you can come up with the extra money to get the bigger one it's probably worth it if you are going to be using it alot. But yes the 100$ unit is a good buy. Don't get tempted to buy the ultra cheap welders, it will blow up and be a waste of money that could have gone to something that works.
I have a similar battery with this long BMS board and when I turn my m365 like Hover-1 Alpha scooter on, the battery out voltage drops to 10V? flashing battery icon in the display I can still measure 4V per cell group while the battery out is reporting 10V. As soon as I turn off scooter the battery out voltage starts to climb back to 37V. Could it be a bad BMS (as it does not seem to affect the state of the battery before the BMS) or a shorted controller?
Use it to buck down to 12v or 24v to run inverters, power 12v accessories like USB PD chargers, DC sources etc etc. Going from higher to lower then using a buck converter to lower wattage means you can use thinner wires for runs from batteries to the converters/source and it’ll be fine. For me I’m using 36V to power 12v inverter and USB PD 60-100watt power sources.
Because there hundreds of thousands of these packs and no one has any vision to use them. They are literally some of the most affordable high quality battery packs you can buy right now.
36v is a industry standard for low power electric scooters and ebikes. Most of these packs are coming from the share scooter market so they are 36v. I don't think he's just focused on 36v packs and passing up others. This is what's available right now.
Because it’s common knowledge that 3 cells in parallel are good for 7A-10A. This is DIY if you don’t know anything about batteries, you should be buying new full priced, warrantied, packs that come with instructions and not these diy packs.
That's not completely accurate actually. Different cells have very different discharge rates. Some being very high but most of the popular name brand cells are around 10 amps like the MJ1, BD and a host of others. In a higher power ebike or scooter pack you might find these cells but most likely the BMS is limited to maybe half of the cells discharge rate. So yes he's correct in saying that most smaller 36v 3P packs are probably going to output 7-10 amps ,I wouldn't say it's common knowledge or any industry standard that you should know.
So there are 30 batteries 865 in the pack? How many volts is each one? Can you use one without a pcb board and just link them together to use for an ebike?
2 banks of 15 with 5 groups of 6 batteries. When you flip them over youll see 6,6, (3+3), 6,6 battery ends strapped with 5 buss bars. Tops are hidden by BMS.
I have the 36 V scooter battery. I am using a step down converter to convert it from 36v to 12v to run a 12v refrigerator. Is it possible to build a 12V charger that I can use within my SUV to charge the scooter battery while driving down the road?
If you never got any help, you could always get a 12v ac inverter and then get a simple 36v lion charger “it’ll say 42v because that’s what it charges up to” and use that to charge it through your SUV’s car charger port
@@jehugarcia so we would only have to make a special connection to fit the charge port wire or chop it off and make our own connection to match a 36v charge connection right.
