1. The battery tester is according to the international standard design, testers' each channel of the system has an independent constant-current source and constant-voltage source.
 2. The battery load tester internal electrical power supply uses the high efficiency switching power supply, the energy conservation effect is remarkable, each power tube has the independent protection circuit, guarantees the Equipment works with safety and reliability.
3. Measure adopts four wire method, decrease contact error, increase measure precision.
4. Each channel is independent With high efficient cooling system, Equipment can work 24 hours with full load.
5. Hardware adopts double loop control, can change from constant current to constant voltage without pinnacle, protect battery
