1: Specially used to measure 18650 battery capacity

2: The integration of charging and discharging eliminates the tedious operation of disassembling and assembling the battery to replace the charging and discharging of the device

3: The size of the discharge current can be switched and it is convenient to use

4: Small size, easy to carry

5: stable performance

This product is a 18650 battery capacity tester, which is specially used to measure the capacity of 18650 batteries. The 1.77-inch TFT display can simultaneously display information such as battery internal resistance, capacity, voltage, current, power, etc.; The tedious operation of charging and discharging equipment; preset three modes of automatic, charging and discharging, after selecting the corresponding mode, start the equipment, and the program will run automatically; the size of the discharge current can be switched for convenience.

technical parameter

 Install the power supply 18650 battery and the 18650 battery to be tested;
