Parallel charging harness for up to 4 individual 1s batteries equipped with the JST PH 1.25 connector. 

Does not work with JST PH 2 connectors

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.

Instructions:
- plug cable into charger
- connect 4 discharged batteries
- charge at 1S voltage and combined 1C current

example:  4x 500mah batteries, the combined capacity is 2000mah, so a 1C charge rate for the combined pack is 2A.
