Safe Charging Logic

When the charger is first plugged in, the initial current stabilizes at the rated 2A, with voltage rising slowly. After reaching the rated 54.6V, the current gradually decreases. When it drops to 10% of the rated value (about 0.2A), the charger determines the battery is full and automatically stops charging (even without unplugging).

First, perform a fast charge up to 80% Then, switch to slow charging to protect the battery. And automatically stop the process when the current drops below 10%.

How To Find Out If This Product Is Suitable For Your Device？
