Directly connecting two packs in parallel is not recommended; use diodes to isolate the packs (two BMS’ conflicting each other!!!). If you don’t use diodes, the packs will not last. Common Cathode Diode will cost $25 on DigiKey…Hey kauaikit, watching yours and BB posts , getting ready to swap out batteries on original 24v model / controller . Chatted with BB thru this site yesterday but as it all seems to come back around to you I thought I'd reach out. To clarify
1. 2 x 7s5p will fit (maybe some slight modification to Battery box). these ? wouldnt they give me 32Ah??
thanks in advance Mike
2. original charger will handle charging ,(they come with a charger anyway). you mention adjusting it to 29.2 is that the 2 little white screws?? How do you know how much to turn?
3. I dont need to install diodes or anything complicated (for me)
Yes two 16Ahr packs will get you 32Ahr….
And yes, x2 7s5p packs will fit with plenary of spare room. Box mods are not needed. I just added holes for the charge ports and two Drok battery meters….
