Over current protection

When the output current exceeds 5.8A, the charger will turn off the output and return to normal charging after the fault is removed.

No damage

Short circuit protection

When the output terminal of the charger is short-circuited, the charger has no output, and the input is less than 3W, the normal charging will be restored after the fault is removed.

No damage

Reversed connection protection

The charger will shut off automatically when the battery polarities are reversed to prevent the charger and battery from being damaged.

No damage

Over voltage protection

The charger will shut off automatically or limit the output voltage in a certain value, when the output of charger is overvoltage(> 31V).

Shut off or limit the output voltage

Prevent backflow protection

When the battery is fully charged and the charger is unplugged, the power of battery won’t flow backward as it is still connected with the charger.

Battery current injection less
than 1mA.

Timing protection

2h±10minutes

Precharge timing: When the battery voltage is greater than 14V ±1V, start timing, if the battery voltage is still lower than 21V ± 1V after 2h ± 10min, stop charging and flashing red.

Timing protection

10h±1h

Constant current timing: When the battery voltage is greater than 21V ±1V, start timing, and after 10h ±1h, if the battery voltage is still lower than 29V, stop charging and flashing red.
