I am the happy owner of a H920 plus(after upgrade) - but I have never used the Proaction - before now. I have the battery (Li-Ion) and the lead for charging, but it seems I am missing a balancing cable since a connection error is reported as I am trying to balance......or should I chose the Charge program - I am getting a little scared here since the manual is a telling Balance Charge and I am not very experienced in this. Do I need a balancing cable for the Proaction battery - it do have a balance connection it seems, or what should I do. Advice please, if possible.
