Choose a suitable charger in combination with the battery.

First, select the appropriate AC input voltage and appropriate input frequency according to the country’s mains

Secondly, according to the type of battery, the capacity of the battery and the characteristics of the battery charging curve, select the appropriate charging voltage and charging current.

Finally, we must choose a charger with multiple protection functions. For example, overvoltage protection, overcurrent protection, reverse connection protection, short circuit protection, and overheating protection. Quality assurance is always the first important requirement.
