Hi

Been gifted a dead super 73 rx pack. The bms , highly propriety, is dead but cells are pretty new samsung 21700 50e (x 52 cells)

Never seen 6 pins on battery before nor such a long slim BMS

I'm going to tear down the 13s 4p config and rebuild with as 10s 5p pack for my 36v bbs02 plus a common dumb BMS of some description. Going down to 50 cells will give me enough room for one.

Just putting the pics for interest really. I've not seen a pack quite like this before. Solid quality build though imho. And I quite like the case shape
