Product Q&A

Q:How to choose the suitable BMS?
A:
Please provide the battery type (3.7V Li-ion or 3.2V LiFePO4), the number of cells in series, the peak power watt of the load or motor, and the intended application. We will then recommend the suitable BMS for you.
Q:How to activate the BMS?
A:
There are three methods: 1) Use the activation switch on the power board. 2) Press the button on the Bluetooth module. 3) Connect the B-line to the total negative pole of the battery pack during charging.
Q:What is the balance function and do we need cell balance?
A:
When a cell reaches the balance voltage (4.18V for Li-ion, 3.6V for LiFePO4), it starts discharging at 35mA to equalize with others. If voltage differences are large, the effect is minimal, and replacing cells with large voltage gaps is recommended.
Q:What type of charger should I choose?
A:
Use specific lithium battery chargers, not lead-acid chargers. For LiFePO4, voltage equals strings x 3.6V. For Li-ion, voltage equals strings x 4.2V. Lead-acid chargers may lack proper overcharge protection for BMS.
Q:Do you have a Minimum Order Requirement (MOQ)?
A:
No, we do not have an MOQ. We accept orders starting from 1 PCS and can provide various capacities and sizes based on your specific requirements.
