I love this! Any chance you could share a quick how-to with regard to the led light string.
Goddamnit. Iām not buying more cells this week. This is a very good price for these, and I expect they can be pushed beyond those numbers (BHU is always conservative with discharge ratings), Iāve seen 15-20A continuous charts on these cells.
Theyāre not gonna compete with 40Tās and P42As but they will probably have MUCH longer lives. Tesla cells have pretty insane longevity historically. Youāll find packs from Model Sās that are a decade old by now and had 100k miles still capable of 80% of original capā¦

Few meepo/china packs that I had to rebuild/replace bms or cells were actually decent. Fishpaper under balance leads, fishpaper between groups, everything secured in place. I was actually amazed.
Old meepo pack vs new 10s2p p42a pack with meepo bypassed bms:
Ya same here, I was shocked that the balance lead were nicely isolated.

For anyone having a similar issue. LLT checked the PCB which was ok and asked me to check temp sensors and connections. Temp sensors were ok. I reconnected everything, tightened NESE tabs and it is fine nowā¦ seems something was loose that I missed. Cheers to all that read this and apologies if this wasnāt the right thread.

Iāve got a BMS with B- , P- , and PC- . Anyone got some thoughts on charge only wiring ? Originally the PC- went to the charge port negative, P- went to a xt60 negative, and B- went to the battery negative.
@PickSix24 you would technically only need to wire pc- and b-. what used to be p- would be gone. Youāll need to make a direct connection from battery to esc rather than through bms

Ok thanks, thatās what i was thinking. The labeling through me for a little loop. Glad I wrote down what the original connections were lol.
this needs a reference topic we always answer this question with.
In the mean time Iāve seen Beautiful diagrams! NO WORDS (SERIOUS). with a link to specific diagrams. but I didnāt find the one to link to. sry.

I more or less got confused by the pc label. Hadnāt seen that one before.
Lol I watched some dude on YouTube for 30 minutes and still didnāt understandā¦then I went on to scare the shit out of my classmates by making a bomb in a woodshop

knock-knock on w00dā¦ I still havenāt had the bright-flash, burn multi-meter probe, 
I have a healthy respect for the damned thingsā¦ we had a customerās bike catch on fire in the shop because of a lithium fireā¦ the bike didnāt burn, we cut it out with bolt cutters and threw it in a 5-gallon bucket of waterā¦ and watched it boil the water
his electrics were all fucked up and he was throwing 20v at his 12v litium battery
