HI
Have a 13s5p battery pack and its not charging or disharging.
The Pack was bought with an ebike 2 years ago and used twice.
No charging was done till now so i would say 18 months has gone by hence the problem.
I have measured the voltage at the BMS pins and i get
pin1 4v
p2 8v
p3 12v
p4 16v
p5 20v
p6 24v
p7 28v
p8 32v
p9 36v
p10 40v
p11 40v
p12 44v
p13 48v
i have measured voltage at p11 which is 0.
Does this mean 1 of the cells within the pack is totally dead?
Can i use a different manufacturer as i cant seem to source the exact same samsung 18650 26e cells?
Its an unusual layout see below. its the middle pack 3 thats the problem.
