Dear forists,
I couldn't walk by this slightly damaged battery pack which I'd like to reuse, preferrably complete with its battery management system.
I couldn't find any info on the exact pack or its BMS, and there's some repair needed, so I need some advice.
The pack has been smashed into something, resulting in some severed cables (to the battery level indicator and charging port) and one crushed IMR Li-ion cell. The main connector is still intact but did not show any voltage above 1V. The whole battery still reads at 37V (10S 5P @3.7V).
I took it apart and shot some photos:




At the moment these are my questions:
- Could somebody point me to any datasheet or description of a similar battery pack or BMS that I could use?
- How might the connections A B and ID be used, are they essential to use the board?
- I'd replace the crushed cell with a cell of the same type (INR18650MH1). Probably not a big deal, would you object?
- In lieu of a matching charger, what could be the most prudent option for charging such a pack? Just stick 42V to it? Might it work with a lower voltage, say a 19V laptop brick?
Here's hoping to read you soon, thanks for your advice and your time!
Best regards
Chris
