Product information:

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

Matters needing attention

★The charging current of each layer is not recommended to exceed 2a, otherwise the battery may generate heat (for example, if there is only one layer, choose 2a charger, and if there are two layers, choose 4a charger).

★Look at the circuit board with the battery orientation,and all the batteries cannot be staggered in the same orientation.

★Don't connect the power supply with the wrong positive and negative, there are signs on the circuit board, pay attention to observation.

★Product single circuit board option, excluding the battery in the photo.

★The list price is the price of a circuit board or a battery.

★The direction of battery installation is subject to the mark on the cirucit board，not the mark on the plastic battery box.

★★★★Please purchase at least one BMS. BMS can provide charge and discharge equalization function for the entire system (multiple battery boxes) at the same time.
