EC5 w/ JST-XH ParaBoard 6-Port Parallel Charging Board:

Has EC5 Male plugs and JST-XH balance taps.

This device is to be used with a balance charger to simultaneously charge multiple lithium batteries in parallel. By this method you can significantly save time on battery charge process.

Each board has six set balance ports, from 2S-6S and six EC5-plugs or T plugs depending on the model. Since these ports and connectors are arranged in parallel, a EC5-plug and a balance port can be randomly matched for battery charge. These ParaBoards can be used for charging up to six batteries at the same time.

Paraboards can only be used with batteries that have the same number of cells. All of the packs that are to be parallel charge should be in the same discharge state (the difference in voltage between each cell should be no more than 0.2v)
