Buffer for unmatched batteries.
If we are charging a multicell battery and the cells aren't matched, we may risk overcharging at least one. Therefore, we may subtract this constant per additional cell in battery to allow for a "buffer".
If this is changed to something higher than (CELL_VOLTAGE_MAX - CELL_VOLTAGE_LOW), and the number of cells is great enough, the limit BAT_VOLTAGE_LOW will become higher than BAT_VOLTAGE_MAX. This will cause the charger to keep trying to charge, but instantly finishing because the battery voltage is already at max.
