You can't see any balancing mode from the outside unless you have a BMS with LEDs that light up when the bleed resistors are open, like the old Ping batteries. The only way you can tell with yours is to put your finger across the bleed resistors when the battery is fully-charged and the charger still connected. You should be able to feel them getting warm. Try it with the battery switched on and off to see if there's a difference.Hmm thats interesting.Everything ive learned so far from people says the opposite.when i had my issues recently with the badly balanced bbshd battery.i trickle charged with a mobile phone charger all the cells to the same voltage,when nearly drained. Then when i charged switched on, for the first time ever it went into balancing mode.with the charger turning on and off for several hrs after the green light. Until the cells all were equal at 4.1v. It had never done this before when the battery was switched off during charging.
When you thought that you saw your battery in balancing mode, what brought you to that conclusion?
