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).
Usage Example:


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.
Specification:
- Cable Length: Approx. 5cm
- Cable: AWG #
- Connectors:
- 2 x JST
- 1 x T-Connector
- 1 x 3S Charging Connector (the white one)
Package includes:
- 1 x 1S To 2S Charging Cable for 3.7V JST Battery (w/ T Connector Output)
** Please beware that all joint batteries must be same capacity (same mAh), otherwise it will be dangerous.
