What Year is your car? Is that the Watchdog you are using?

I believe that best way to try balance the battery on your own, is to drive vehicle till there is no charge left in the Main Battery, then charge it using Level 1 Charge till full.

Other members have described the process using the supplied 'granny charger'.
(AKA the level one charger.)

After the battery reaches 80% the charging process slows down, and there are low current draw periods where the car's on-board software is leveling the charge across the cells.)

This is probably one of the reasons why Mitsubishi recommends against using fast chargers.
