Hi all,
I was given a Bionx battery by a bike mechanic who said the BMS card is dead. Bionx had remotely diagnosed this, disabled the battery and said it could not be repaired. The cells seem to be okay.
I cracked the case and took a look. I'm reading 35, 35, 24 and 35V on a termination block.
Here's the full set of images:

They seem to be getting truncated on this page.
I'm not really sure what to do with this battery. It potentially has a useful life span yet my skills with batteries are pretty limited. I've purchased a Ping battery in the past and even replaced the burnt BMS on it, mounted it in a case and used it for years.
Right now, with the Bionx, I could see removing the card, probably could get that done without zapping something or myself or ruining a cell. At that point, what to do? I see these cheap BMS cards on eBay. To get from this battery in its current state to a working, safely rechargeable battery is a bit of a leap.
Just curious what you would do with this? Perhaps the best bet is to recycle it, though it is in a nice form factor and I would love to have a hefty power pack on my cargo bike.
