Note:
The selected protection board current should not be less than the controller current limit of the product you are using.
Lithium battery should be charged with lithium battery special charger, do not use lead-acid battery charger, lead-acid charging may have high voltage breakdown protection board MOS tube, resulting in protection board overcharge is not protected.

Charger voltage setting:
Use your battery pack number *4.2V This is the charging voltage of the non-ferrous lithium battery. The charging voltage of the iron-lithium battery is the number of battery strings *3.60V, and the charging current standard is 0.2 times of the capacity.
