How to use:

Note: When the battery is connected for the first time, there may be no voltage output between OUT+ and OUT-. At this time, the protection circuit can be activated by charging with 5V voltage. If the battery is short-circuited from B+ B- and then connected again, it also needs to be charged. Turn off power to activate the protection circuit. When using a mobile phone charger for input, please note that the charger must be able to output 1A or above, otherwise it may not charge normally. The TYPE C USB female socket and the + - pads next to it are the power input terminals, which are connected to 5V voltage. B+ is connected to the positive electrode of the lithium battery, and B- is connected to the negative electrode of the lithium battery. OUT+ and OUT- are connected to the load, such as the positive and negative poles of the mobile booster board or other loads.

Connect the battery to B+ B-, and insert the mobile phone charger into the USB socket. If the red light turns on, it means it is charging, and if the blue light turns on, it means it is fully charged.

Note: When charging, the load on the OUT terminal should be disconnected. The positive and negative poles cannot be connected incorrectly. Please use it according to the specifications, otherwise the booster board will be directly damaged.
