Ok got myself the Battery Doctor and have a question.

I will be balancing whilst charging, I have the option to set the lower voltage limit before the balancing starts...do I leave this at default value of 3.30v or change it to another volt limit, range is 2.5v to 4.2v.

In previous post people have mentioned not to charge over 4.21 volts and give the impression their balancers can stop this...the Battery Doctor does not have a upper balancing voltage i.e. preventing it going over 4.21...is this another problem?

Thanks.

Leave the lower voltage limit to 3.30v per cell.. That is the minimum voltage you want your cells to be at (lipo cutoff uses the same or slightly higher voltage range). I never really heard of a minimum voltage to start balancing, but I guess each manufacturer is different..

If you were to discharge your cells below 3.30v (i.e. run an ESC without an active lipo cutoff), then there may be no way to recover/recharge the cells in the future. Especially if you bought a really cheap lipo battery that uses sub-par cells..

I am not familiar with the Battery Doctor since I have only used chargers that have integrated balancers; but your charger should have a setting for lipo voltage peak detection of 4.2 to 4.21v per cell. The charger should cut off when it detects this per-cell voltage. You charger should also let you configure the Mah setting (3300Mah, 5000Mah etc) of your battery as a backup to the voltage detection. Just in case your battery capacity peaks before the cell voltage is topped off.

Hope this helps.
