The charging current of a 15C battery can be very high. You can buy a charger with an output voltage of 25.2 V and a current of ten amps. Of course, five amps can also be used. but the voltage is empty. It should be 25.2. If exceeded, it is dangerous and can easily lead to overload. If it is too low, the battery. is not fully charged.
As for the charging current, it's up to you. If you want to be faster, choose a larger current. If you want to be safe and consider battery life, choose. a smaller one. It can be used from 2 to 10 amps.
Advantages of use
1. There is no problem of battery leakage. The battery does not contain liquid electrolyte and uses colloidal solids.
2. It can be transformed into a thin battery: with a capacity of 3.6V 400 mAh, its thickness can reach 0.5mm.
3. Batteries can be designed in different shapes.
4. The battery can be bent and deformed: The polymer battery can be bent up to about 90 degrees.
5. Can be made into a single high-voltage battery: Liquid electrolyte batteries can only obtain high voltage by connecting multiple batteries in series. Polymer batteries can be made into multi-layer combinations in a single battery car. they don't have liquid to reach high voltage.
6. The capacity will be twice that of lithium-ion batteries of the same size.
