my charger usually stop the voltage at 3.67 but since i paralleled they dont get as high idk what it is. Where do i put the probes at both on negative ?

what i did so far is i grouped them into 4p at a time for the time being but the voltages are 3.31-3.34 and they wont go any higher basically the charger would turn on then turn green after a minute or 2 also right before i made this thread they were charged up i forgot to mention that and so...

The cells that were under 2v they sat like that for a month or so till i got the single cell charger but they were taken out of the pack and replaced with cells from the cells i had on hand. i know how to series but i never paralleled at cell level before and the the only way i know i can do is...

This is the resting voltage after a charge this is when i had the 72v signalabs this is the original pack i put together 1# 3.30 2# 3.30 3# 3.30 4# 3.30 5# 3.30 6# 3.30 7# 3.30 8# 3.26 9# 3.30 10# 3.30 11# 3.31 12# 3.43 13# 3.30 14# 3.30 15# 3.30 16# 3.30 17# 3.30 18# 3.30 19# 3.45 20# 3.30 21#...

I don't think its the charger cause the cells the been in my pack the longest read within .01 of each other when charging the highest the whole pack voltage i seen on charging was 86.7 and it shuts off due to the Bms reaching its HVC for the cells that are messed up they reach 3.9v

Nah Your not being an ass its just a bit incoherent lol, I need to source some 12ah cells so i can rebuild and i think the bms im running now is fine even though the other failed on me but im always looking for a new affordable solution for a bms, I do a short trips of under 8 miles each way...

Sorry about that hope the next on is a bit clearer to understand!

Dnmun , Ive never ran without a bms ive done my research lifepo4 needs a bms. I honestly dont think nothing was wrong with the cells beforehand until i tried the 72v signalabs bms some came out of the box with issues or if after i hook it up and ride the bms would cut off and i get one or two...

well i dont think the vendor i bought it from would give me bad cells and no i never shorted the pack i did do series and the one or the bms 2 mosfets blew but i followed the diagram to hook them up to series them at first the were 2 36v 50/100a bms but i switched to 72v signalabs and some...

ive had this battery for a year and 3 months now and been having problems with it almost every since i got it if it was a Bms "When i used the signalabs" issue it was a battery issue when my other battery cells were 3.20 -3.13 at the highest and the lowest was 2.15-2.60 and i was getting help...

i recommend you get like a 60 amp fuse it will give some head room so you fuses dont blow ive been there with the 72v Sla pack and ive never blown a fuse i still have a few left over when i had Sla battery.

Yea i know they aren't born with holes lol , But everyone doesn't want to use a drill or has the ability to use a drill properly to make such adjustments.

O Only thing about drilling to make the rim is the it can possibly degrade the integrity of the rim. So people what are our real option of using bigger gauge spokes on bike rims ?

Biohazardman, Well Said !!! Any recommendation for a wide strong rim in the 30's -40's mm range ? I personally like to over build things with those Weinmann's rims was only for a quick fix except from my front rim i like that one I'm not a real hard rider and IMO they are better than the...

No problem Biohazardman. I will relace my wheel soon it's just that its so many to choose from i have a Weinmann xm260 on my front rim and it has taken a beating like many pot holes that will make a almost quarter of your rim disappear with my big but on it and i didn't flip off the bike due...
