5V 2A 955565-2P 10000mah Booster Battery Small Microcontroller Intelligent Lock LED Lamp Power Supply 4.8V Lipo Battery

The working current of all 5V boost batteries is not allowed to exceed their nominal value,

The charging current is not allowed to exceed 2A (1C for capacities below 2000mah, which is the nominal capacity value of the battery),

Devices with peak current (including but not limited to startup/stall current) exceeding the working current of the battery cannot be used normally, especially devices with motors/motors or capacitors/inductors, microcontrollers or high-power lighting fixtures, etc.

Charger:

Only allow to use a 4.2-5V non intelligent constant voltage charger (not a charging chip!) or computer USB 2.0 interface for charging! Intelligent chargers, such as those with 9V-12V intelligent transformers, cannot charge and may even directly damage the battery.

The 5V boost battery (charging is prohibited at the discharge port) can be discharged at the charging port, which has a dual layer function of charging and discharging,

Beware of short circuits when detecting charging port voltage! Once a short circuit occurs, it will trigger the protective action of the boost board, automatically cutting off the circuit, and in severe cases, it may directly burn the boost board! After cutting off the circuit, it is necessary to recharge and activate the boost board, and even disassemble the entire circuit board to charge the battery cells before connecting the circuit board to activate before use,

Burn out the booster board, only the booster board can be replaced,
