Yeah it connects all the cells in a 12s2p config, the pcb should be safely handle 30 battery amps.
The bms is just a cheap ass bms for each 12s2p pack, the high current path doesnt run through the bms, but the bms will be able to shut down the Unity in case of a fault… well that’s the theory lol
Wait I’m a bit confused. Will a single unity fit with a 10s4p? I can make some chanels for the phase wires if nessesary but the Gap is wide enough right?
LOL, im just gonna stop telling if anything fits or not. The dimensions of the enclosure are on the very first post. The depth is 22,5mm, up to the builder to decide if 2X700 fit or not
The PCB idea is really good, maybe even for flexy decks
Will each cell be connected to the PCB or each P group? I thought of printing some supports for each cell, each is glued to the PCB and the cell glued to it then wired/fused
Each individual cell will spot welded on the pcb, the P and S connections will be done on the pcb. The tracks are wide enough to safely pass 30A. Im not a believer of cell fusing on these small packs… but it could be done.
Once the cells are installed, i left a gap to insert fish paper in between each S connection. Then i’ll inject RTV silicone to “mount” the cells on the pcb
