Hello everyone,
I salvaged this battery pack from a bluetooth speaker and there is 5 cables coming out from it. I would like to know what is the white wire for and why there are 2 ground cables and 2 positives?
How can I charge the battery? Can I use a 5v battery charging board using 2 of the cables only?
Thanks in advance
Kimi
