2 x USB-C 18650 Lithium Battery Charger Module 1A Protected PCB Charging Board

​2 x miniature linear battery charger / powerbank pcb circuit board module.

This useful little board is ideal for battery charging with a powerbank battery storage function. The output / load voltage from the battery can further be used to power your circuitry such as a Buck Convertor or led lighting.

Based on the TP4056 1A linear lithium ion battery charge device this board is great for DIY projects when working with the industry standard 18650 battery. The board is also ideal for testing and reviving 

The board is extremely compact and measures only 27.6mm x 17.6mm

The board is fully protected for under voltage and over voltage as well as over current protection. Battery voltage range protection is done via the DW01A battery protection IC.

The function of this board is to charge parallel connected 18650 batteries, (no more that two voltage balanced batteries recommended). The input voltage, typically 5V, is applied via the USB-C socket or via the pcb lands beside this connector. Two further connections are provided for the battery positive and negative as well as the load positive and negative. The load voltage will remain whilst the battery retains charge. Connection of a load is optional as the board can simply be used to charge 18650 batteries to the maximum terminal voltage of 4.2V

There are two led indicators on the board. Red is illuminated whilst charging and green indicates a full charge. With a fully charged battery and no load the leds will be off.
