Each Bantam e-Station parallel board can hold only ONE Lipo battery pack of 3S, 4S, 5S or 6S. The parallel boards do not support 2S batteries. An unlimited number of parallel boards can be connected together simultaneously.
If you have 2 or 3 batteries you wnat to charge in Parallel you need a board for each battery
The Bantam e-Station parallel boards utilize Thermal-resistor Indicators for the safe parallel charging operation, The red
indicators may turn black when there is a voltage-difference between any of individual cells. If any one or more indicators are black, DO NOT PARALLEL CHARGE as the voltage difference between cells is too great. A slight black tint is not a problem to continue to charge as the indicators will return to red when the voltage difference between the cells are minimized.
This board is for standard battery balance connectors model JST XH used on 3S, 4S, 5S and 6S Eflite, ParkZone, Align and many others.
Note: You can also use this board for 4S, 5S, and 6S packs for TrueRC, PQ and Hyperion batteries.
