JST-PH 2.0 4-Way Parallel Charge Harness
by RMRC

Parallel charging harness for up to 4 individual 1s batteries equipped with the JST PH 2.0 connector. 

Does not work with JST PH 1.25 connectors found on traditional 1S packs. 

CAUTION

• It is best practice to have all packs near the same voltage when parallel charging. A full discharged pack and a nearly charged pack on the board at the same time should be avoided.
