Hey there
I do have some problems with two 80v kobalt battery-packs. the batterys are used for mowing machines. both of them are well treaten and almost new. i gues one has arround 1000 cycles and the secound probably 500. what happened:
The mowing machine everytime died after 5min work. i disambled the two batterypacks and found some dead kobalt cells. i replaced the cells and charged every cell to exactly the same voltage. sadly when i put the battery in to the mower it again died after 5min. i guess the bms cutts off to early. could there be some remembering function that didnt reset to the new capacity and still stays in "batterie dead" mode ? are there any possibilities to reset or fix a bms like this? i really hard tried to find out something about it but hadnt success so far.
I would be really really gratefull if you guys could give me some help! tanks
