6-channel 1s lithium battery charger for model aircraft, high voltage 4.35V BT2.0 connector.

 
Overview
This is a 1-second high-voltage lithium battery charger for model aircraft. The charging cutoff voltage is 4.35V, and it uses a BETAPPV BT2.0 connector. The charging chip is ME4057DSPG. Power supply is limited to 5V input only! Wide voltage input is not supported!
 
Modifying the resistor values ​​(R2, R3, R4, R11, R12, R13) allows you to configure the charging current
: 1.1kΩ for 1A and
2.2kΩ for 0.5A.
Replacing the chip allows you to charge batteries of different voltages, as shown in the diagram below.
