Replacement BMS for Bosch powerpack 400

[Oliver.M.]

Hi all, I was recently given a water damaged PowerPack 400 and I have replaced several chips on the PCB with no joy, the LED's on the pack do nothing and it doesn't seem to take a charge full stop. Does anybody have a spare BMS I could have / buy or does anybody know of a place I can purchase one?

Cheers,

Oliver.

If you're not going to use them in a Bosch system you could go after market bms or just skip it. I've been running some stripped down Bosch packs with very little drift between the groups.

Hmm, Unfortunately I’m repairing it for a friend who would be using it with a Bosch system still so going aftermarket / stripping down the pack isn’t an option.
I’ve read about a lockout chip on the PCB, would this completely disable the BMS?

No info on that, sorry.

Ok, thanks for your help and advice. I’ll keep looking around. I’m sure somebody must have a spare lying around that they no longer need.
