DF Robot 2 x 18650 Holder - 3.3V & 5V Out

This easy-to-use 18650 battery holder with dual-slot offers micro and type-C charging inputs, and it is suitable for two 18650 batteries with five 5V/2A output ports, five 3.3V/1A output ports, and one 5V USB output.

It comes with overcharge and over-discharge protections that greatly extends the lifespan of your 18650 batteries. The onboard DIP switch allows users to switch between HOLD and NORMAL modes. In Normal mode, it auto shutdowns when the current is too low, while in HOLD mode, it keeps outputting and does not shut down until the over-discharge protection is triggered.



Please Note: The maximum current is 3A (3A is not recommended), and the output of the current depends on the quality of the 18650 battery. Pay attention to battery polarity when installing. The + and - are clearly marked on the board, and the wrong direction will burn the module.

The module is controlled by buttons. Pressing the button lightly will turn it on. In the on state, pressing the button twice within 1 second will turn it off. The DIP switch can be used to switch between HOLD mode and NORMAL mode. In NORMAL mode, the module will automatically shut down if the output current is too low.

They will flash when charging and stop flashing when the battery is fully charged.
