FAQ

Q: Does this BMS support LiFePO4 or NMC (Lithium-ion) batteries?

A:This BMS is compatible with both LiFePO4and NMC/Lithium-ion batteries. Please specify your battery chemistry when ordering so we can configure it accordingly.
Q: My battery is 14S/15S. Can I use this 13S BMS?

A: No.The BMS must exactly match your battery's series count. Using a BMS with a different series count will result in improper function or potential safety hazards.
Q: What is the difference between "Common Port" and "Separate Port"? Which should I choose?

A: Common Port: Uses a single high-current terminal for both charging and discharging. Benefits: simpler wiring, balanced port wear. Recommended for most users. Separate Port:Has dedicated terminals for charging and discharging. Benefits: independent charging control.
Q: What is the purpose of the "Balancing" function?

A: Balancing is crucial. It acts like a "manager" to keep the voltage of each individual cell in the battery pack equal. This: Maximizes total capacity by preventing the entire pack from being limited by a single cell. Significantly extends battery life by preventing individual cells from deteriorating due to over-charging/discharging.
Q: Does it support Bluetooth APP? What data can I see?

A:Yes, it supports Bluetooth APP connection (via a dedicated module). You can monitor in real-time: Total Voltage, Current, and State of Charge Voltage of Each Individual Cell (most critical data) Temperature, Cycle Count, and Error History
Q: Is it normal for the BMS to get very hot during charging?

A:Slight warmth is normal. However, if it becomes excessively hot (too hot to touch), it is abnormal. Possible causes: Charging current is too high for the BMS rating. Poor heat dissipation (e.g., installed in a confined space). A potential fault in the BMS itself.
Q: Is technical support available?

A: Yes, we provide professional technical support to assist with installation and troubleshooting after your purchase.
Q: What is the Minimum Order Quantity (MOQ)? Can I order samples?

A:We accept sample orders for testing and validation. Please contact our sales team for specific MOQ and sample policies.
