Before designing the 48V battery box, we had 3s12V, 6s24V, and 7s29V, but many buyers also wanted higher voltage, so we designed this 48V battery box.

This battery box is made up of 13 batteries in series. The batteries are installed on both sides of the circuit board. The size of the previous 7s battery box is similar to that of the previous 7s battery box. There is no change in the overall position of the 6s battery.

Take a 3000 mA battery for example, a circuit board full of batteries is 48v3ah, and you can stack the number of battery boxes according to your actual needs.

We 've got two for you, 20A and 45A. In terms of volume, 45A is much larger than 20A, but the function is similar. If there is no particularly high power requirement, 20A is recommended. The protective plates have the functions of charge and discharge protection, discharge current protection, temperature protection, voltage equilibrium, and balance impulse. Each circuit board has a 15a insurance policy. If one battery has a problem, it will not affect other batteries

Here are the battery box charging tips

1, the limit of battery box protection plate charging is 8A, the charging current of
each layer of battery is not recommended to exceed two amps. If there is only one battery box, it is recommended to select a charger with a current lower than two amps. If it is a two-layer battery and recommended to choose a charger up to 4A. By analogy, if the current is excessive, the battery will heat up or damage.

2, charger must choose constant current charger, can not choose constant pressure power supply, constant pressure power supply will cause the battery to heat up.

3, 3 s needs 12. The 6-volt charger can be filled, and the 6S needs a 25.2 Volt charger to be filled. If the voltage is below this value, it will be dissatisfied.
If the charger voltage is more than 1 Volt this value may cause damage to the protective plate.

4, if there is no suitable voltage charger, or only constant voltage power supply, we can choose the constant current lift pressure module, the ordinary constant voltage power supply into an adjustable current constant current power supply.
If you use a solar panel to charge the battery, you need to bring your own voltage control module. If the output voltage of the solar panel is too low, you need to increase the pressure boost module. If the output voltage of the solar panel is too high, you need to increase the pressure relief module. The specific wiring can contact us.
