2-Way 18650 Battery Holder
This easy-to-use 18650 battery holder with dual-slot offers Micro-USB and USB-C charging inputs, five 5V 2A output solder pads, five 3.3V 1A output solder pads and one 5V USB-A output.
The board includes over-charge and over-discharge protections that greatly extend the lifespan of your 18650 batteries. There is no reverse-polarity protection onboard – please ensure you fit your batteries the right way round with the + and – clearly marked on the board!
The onboard DIP switch allows users to switch between HOLD and NORMAL modes. In Normal mode, the board will auto-shutdown when the current is too low, while in HOLD mode, it will keep outputting and does not shut down until the over-discharge protection is triggered.
This battery holder can be used as a power source for microcontrollers, outdoor equipment and other low-power devices.
Note: The maximum current is 3A (however 3A should be considered a temporary peak current only), the output also depends on the quality of the 18650 battery.
We also stock 1-way and 4-way versions!
