Not sure if this has been discussed before, but one thing I always keep in mind when it comes to the BMS and balancing, is it’s balance current, for the most effective balancing and to not burn out your BMS, make sure the current your charging at by the time it starts balancing is equal or close to the balance current. if it’s too high the resistors can’t mitigate more than they’re rated for, they heat and burn, and cells get over charged
