1. The  tester is according to thebattery tester international standard design, testers' each channel  has an independent constant-current source and constant-voltage source.

2.Battery tester internal electrical power supply of uses the high efficiency switching power supply, the energy conservation effect is remarkable, each power tube has the independent protection circuit, guarantees the battery load tester works with safety and reliability.

3. The battery tester adopts four wire method, decrease contact error, increase measure precision.

4. Each channel is independent With high efficient cooling system, battery tester can work 24 hours with full load.

5. Hardware adopts double loop control, that battery tester can change from constant current to constant voltage without pinnacle, protect battery.
