💡 Frequently Asked Questions (FAQ)
Q: How do I know if this BMS is compatible with my battery pack?
✔ Battery Type: Must be LiFePO₄ (3.2V per cell).
✔ Battery Configuration: Must be 8S (24V setup).
Q: What’s the difference between Common Port and Separate Port?
✔ Common Port (P-) – Charging and discharging share the same terminal, making wiring simpler.
✔ Separate Port (C- & P-) – Charging and discharging use separate terminals, allowing different charge and discharge currents.
Q: What charger should I use with this BMS?
✔ LiFePO₄-specific chargers only! Avoid using lead-acid chargers.
✔ Recommended Charge Voltage: 28.8V – 29.2V for 8S LiFePO₄ packs.
Q: How does the balancing function work?
✔ The BMS activates balancing at 3.6V per cell, ensuring equal charge distribution.
✔ If voltage differences between cells are too large, manual balancing may be required.
Q: Does battery capacity (Ah) affect the BMS current?
✔ No. The BMS current rating is based on motor/controller power needs, not battery capacity.
Q: What BMS size do I need for my system?
✔ 250A BMS is ideal for 3000W – 5000W power systems.
