4 x 18650 power supply.

Power Supply Module

Power supply using 4 x 18650 batteries / charge accumulators, with 5V and 3V3 outputs, onboard charge, micro USB.

It has overcharge and deep discharge protection, which significantly extends the life of the 18650 battery(s). Works with non-protected cells; the holders will not accept 18650 cells with protection, they are just 2 long.

With the integrated DIP switch, users can switch between HOLD and NORMAL modes. In Normal mode, it will automatically turn off the voltage when the current is too low, while in HOLD mode, it will continue to deliver current and will not turn off until the discharge protection is triggered.
