I have been reading up on the bottom balancing method and have seen voltage settings of 2.75v and 2.7v. If the discharging cuttoff voltage is 2.5v on a calb cell, wouldn't it make sense to bottom balance to that voltage?
I was wondering what an ON-BOARD bottom balancing system might consist of.
1) an isolated 3.43 (or whatever half voltage is) dc/dc or ac/dc protected low amp charger for each cell. (could run on accessory battery,AC or even pack voltage.)
2) a controller to kick it on then the cells are lower...
