▲Micro USB lithium battery charging module: Overcharge, over-discharge, short circuit and over-current protection, two-in-one charging and discharging protection function. Light state: No load the light is not bright, red light for charging, is full of green light.
▲Note: The ammeter for testing current can only be connected in series with the 5V input terminal of the charging board.，When the voltage is high, the chip will heat up and automatically reduce the charging current so as not to burn the chip.
▲2A 5V charge-discharge module:Trigger mode: low-level trigger (ground). 4 in 1 charge/discharge/lithium battery protection/battery level indicator module. Lithium battery protection function: over-current, over-voltage, over-temperature, short circuit protection.
▲Note: When the load is less than 50mA, the output will automatically turn off after 30 seconds; When the load is more than 50mA, the output will be turned on automatically. Allow discharging during charging. (Note: At this time the output voltage is 4.7/5V).
▲Package includes: 5 x 18650 lithium battery charging module + 5 x 2A 5V charge-discharge module + 5 x 18650 battery box
