Charge AND balance 4 Lipo packs? Series Parallel solution help. Answered
I have x4 identical Turnigy Graphene Professional 5200mAh 3S2P 15C LiPo Packs w/XT60 - and I need 22.2v out of them for a portable boombox project.
I have x2 12S 30A BMS's to balance / charge on board and a 600w 48v 12.5 A power supply.
By wiring up the battery packs in series then parallel to get the 22.2v output - if I then connected the BMS (either by directly wiring to each cell or using the pack balance plugs) would it would cause a short circuit through the balance wires?
The ideal solution would be a wall plug power supply that plugs into the (sealed) boombox and charges all of the batteries through the BMS's. Is there any way of achieving this through parallel charging (not a fan) or could I switch easily between the two wiring set ups?
I'm trying to avoid buying a £200 Lipo charger and connect the batteries directly or keep disassembling the boombox every time it needs charging.
