I have this new BMS I use that has an aluminum plate on both sides with one side sinking the smd resistors for the balance circuit and the other for the main bms fets.
Now, I chose to mount it so the balance sink is facing outside since I know from experience that this side gets pretty hot on a regular basis.
But, I never tested a BMS that has the fets on a separate side to see how it behaves under high currents (let's say 150A for a 72V pack), does it get hot?
I need to know how much to pad for distance away from the cells.
