Ok so I have 2 x spare 36v (43.8V charged) A123 11.5Ah battery packs all sealed with 12 Cell BMS attached and wired up....brilliant batteries.....
But my sensorless controller is stuck on 72V and having just sold my Greyborg and other bits including the much needed programming cable for the controllers I can not adjust the LVC on this controller.
Now I'm thinking about just connecting the two 36v batteries to make a 72V 11.5 Ah pack....problem is the BMS. Understanding that I would have to charge separately each battery...is it possible to link them up in series without having to disconnect the damn BMS each time which wil cause many problems.
Would the BMS be ok if I just hook up the two packs in series and disconnect them for charging?
