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.

If you go to his shop and look for worldwide sellers, there is one in EU that sells bulk cells. But they wont ship to UK so no good for me...

Imagine in South America or Brasil to be more specific... A quick Google search showed some 18650 for 25+usd each...

@@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.

@@tdomingues89 buy from where

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

@@Sk8strings I snipped all the white cables before hand at both ends

@@Sk8strings I wouldnt use a bms in any case EVER I add balance wires now and use an RC battery charger balancer

@@Jacob-og9pz thank you!

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" .

yeap the price on ground shipping went up alot since dec your paying about extra+ $32 or more depends.. (califonia jack the price up)taxxx

He always picks one that works

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

@@guymee thanks!!!

4s lifepo4 is your answer

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.

For anyone who wants to know, harvest only all had bms issues, hence the discount.

Check out the sw-2 by sequre or however you spell it. They have a larger unit and a smaller one. 200+ for the big and sub 100 for the little one.

@@kevins5016 I found it! Have you ever used one of them just curious?

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.

The bigger one is the discharge 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.

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.

@@jehugarcia Save the condescending tone garbage merchant.

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.

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

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.

you can buy a 36v inverter , buy a mppt charger that can charge 36v through solar panel you can do alot with it

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.

36 Volt EBikes are extremely common! Its basically 36 / 48 / 52 that make up the vast vast majority of the ebike market

Sounds like you like paying full price…. Nothing wrong with that

Sustainability! That’s a selling point actually
