Charging 1S (Cell) Battery with only a JST connector one by one is time consuming and also a trouble task, isn't it? Here you can charge three JST 1-Cell Battery at once using an external Balance Charger (eg. RCX B3 2-3S Li-Polymer Charger).
But beware that you need a good balance charger, the best one should be a single processor monitoring each single battery cell, so it will stop charging when a particular cell is full. Bad balance charger may damage the battery.
The Red T-Connector will then become a 3S Battery. This T-Connector is used by some chargers required to discharge the battery during balancing such as iMax B6.
