Hi,
I have dismantled my Bosch 400 active line battery pack, as it was dead.
Finally, from the 40 batteries, 4 were still good, 4 were not so good and the remaining 32 were dead, zero volt or even minus 0.04.
It is a 40 battery pack, 10s2p
Is my assumption that also the BMS is faulty reasonable?
I want to replace all batteries and the BMS. The BMS is not the most expensive part I this renovation.
The Bosch BMS has not only 13 balance wires , it also has a 3wire to the bicycle connector, that I don't see on regular BMS boards.
From the 13 wires, 2 are short circuited and the rest are wired to the 10 plus and to one minus.
Can I buy any 11 wire BMS and forget abut the 3wire to the bicycle ?
advice is appreciated.
Thomas
