Thanks - that makes sense - you are then limited by the heat dissipation from those resistors/FETs and I would imagine the most likely failure point of the whole system. Hope they chose a quality BMS as that would be the $5 part that makes a $1000 worth of cells worthless.
That made me stop and think that this wouldn't work anyway. I was originally thinking of this like say a 4 cell Lipo where you can get smart chargers that balance charge through the entire process. But with 30 cells in the Rise H, there's no way you can do that. So my guess is that it charges...
Just posting this in case there's any other Electrical/Software Engineers on this thread.
I'm thinking we need a monitor that will manage the charger for us. If it was me, just because I already have the right parts I'd need: I would use an ESP32 micro controller where you can say set 90%...
