This bike only has minimal front suspension and I do run my 18650 battery pack on a rear rack :-( t...

Need help with a PING LIFEPO4 BMS was fried Pics inside

Modified my Leaf ebike 1500w controller but forgot my BMS in my 3 year old Ping 48v 20 ah battery is only rated for 40 Amps! Anyone know where I can get a higher power BMS 16s it looks like cells were like 3.34v so it's not a standard voltage nominal like a 18650 is. I pull 2000w uphill and off the ...

Chinese VTC6 Clones are confusing the crap out of me please help.

Ok so these are claimed 3000 MAH 15 AH continuous and 30 AMP peak per cell. They are listed as IMR batteries which are Lithium Manganese Oxide (LMO). Now I have been testing these and they come out to around 2000 MAH per cell. I have used other clones about 2 years back (probably same battery) for a...

Re: What 18650 charger tests cells MAH???

What do you plan on using it for single cells or making a battery pack with 80 to 160 cells in it. Are you just looking for capacity or an internal resistance. What's the big picture. Bought some clones from China Wana test them see how close they are to what they claim VTC6 3120 mah (yea right lol...

Re: MAKING A CHEAP BATTERY PACK WITH CHINESE CLONES? IMR AKA LMO BATTERIES 18650

709A (mine) puts out 650A on the highest setting That is not optimal, in KWeld tread they work around 1200A pulses for .15-.2 tabs and striving for up to 2000A for thicker Nickel. They are shorter but results are better then long low current discharges. That's gotta have some thick stuff! I know wh...

Re: MAKING A CHEAP BATTERY PACK WITH CHINESE CLONES? IMR AKA LMO BATTERIES 18650

bonus tip: also make sure you cover the entire cell with strip. it should not be possible to see the positive end of the cell. you can see you only cover half of the left bottom cell for example. also make the parralel strips longer so it goes over the side by about an inch. that way you can attach...

Re: MAKING A CHEAP BATTERY PACK WITH CHINESE CLONES? IMR AKA LMO BATTERIES 18650

if you use cell holders wrapping is not needed. just put a disk on the top so the top edge does not touch the strip. Am I getting safer? I got l thicker nickel strips. Added in battery spacers and top insulation. Btw I had a very hard time getting the strips to stick to the battery with my welder. ...

Well I have all stuff ordered that I need could only find 8x.15mm nickel strips. I disassembled the packs I had carefully came out with 41 18650s that I deemed acceptable shape others I tossed. All 41 cells tested 4.15-4.18v 90% were 4.16-4.17v.

lay them in a brick formation. you need to cut the exess off but they are so cheap it does not matter.
Also a couple cells that i disassembled the hot glue tore some of the battery wrap on a couple i tossed them tho probably best bet?

Thanks I want to also buy a 3d printer and make a case for the batteries too I won't be discharging them near what they can do so it shouldn't heat up much (I hope).

the fake B6's are usually 10 to 20mV off. more if you use crappy wires. check here: https://www.skyrc.com/antifake/indexen.php also: you dont need more padding: you need cell holders. when you put the cell holders on the cells and have a block complete you can put a dab of glue between each cell we...

Re: MAKING A CHEAP BATTERY PACK WITH CHINESE CLONES? IMR AKA LMO BATTERIES 18650

voltage is also a good check. just strip the cells down and use a dremel to get rid of the welding spots that remain after pulling the strips off. in the meantime you can do some capacity testing of you have a imax B6 or something (if not: get one, original please, not fake ebay). try and match the...

Re: MAKING A CHEAP BATTERY PACK WITH CHINESE CLONES? IMR AKA LMO BATTERIES 18650

To be honest also I only checked the voltage on the cells and put them together they all read 3.85-3.88v they are cheap China clones.

Re: MAKING A CHEAP BATTERY PACK WITH CHINESE CLONES? IMR AKA LMO BATTERIES 18650

The batteries are so tight with the strips that if I try to cut the series connection they spark sometimes I'm guessing from the protection wrap getting scraped off? Doesn't make sense to me... P.S. this is the 4s that came apart on me I used thicker stuff for this but had problems with it sticking ...
