Jamestronic CHGR801 Li-ion rechargeable battery charger and analyzer development kit

Product code :



CHGR801 is an intelligent Li-ion rechargeable battery charger and analyzer designed for 3.6V or 3.7V (nominal voltage) rechargeable Li-ion batteries. It has 2 independent channels, each channel can operate in 1 of 4 modes: Charge, Discharge, Discharge+Charge, Testing Mode. When Channel 1 operates in any 1 of these 4 modes, Channel 2 can also operates in any 1 of these 4 modes. Each mode has 4 settings of current level.



1.   Main board (PCB dimensions 90mm x 105mm)

2.   AC 100-240V to DC 6V, 2A (or >2A) adaptor

3.   Connecting wires : 2-pin wire x 3, 4-pin wire x 1

4.   Push button x 3

5.   Thermistor NTC 10k@25˚C
