F.A.Q.
Q:What is BMS and its function?
A: The BMS stands for "Battery Management System", the main function of the BMS is to monitor and optimize the performance, safety and lifespan of the battery.
Protection function:
1. Overload protection
2. Load monitoring and control
3. Deep discharge protection
4. Cell temperature protection
5. Surge protection
6. BMS temperature protection
7. Active Cell Balancing
8. Short circuit protection
Q: Does the WANROY 48V 100Ah LiFePO4 battery have built-in BMS?
A: Yes. All WANROY lithium iron phosphate batteries have built-in BMS. By the way, almost none of the lead-acid batteries on the market have a built-in BMS.
Q: Will WANROY 48V 100Ah LiFePO4 battery automatically block charging below 0°C?
A: Yes, due to the characteristics of LiFePO4 batteries, charging the battery below 0°C can potentially result in charging failure and damage to the battery cells. Therefore, the Battery Management System (BMS) has been configured with low-temperature protection.
If the temperature is lower than 0°, charging is not allowed, only discharging. When the temperature is lower than -20°, discharge is not allowed.

Q: Will lithium iron phosphate batteries burn?
A: No, LiFePO4 batteries are safer, more stable and will not explode than other Li-ion batteries. For more information on how LiFePO4 batteries compare to other batteries, watch this test video: https://www.youtube.com/watch?v=aIy6S0TdSSE
Q: How does the LiFePO4 battery behave in the event of a short circuit?
A: No, LiFePO4 batteries are safer, more stable and will not explode than other Li-ion batteries. For more information on how LiFePO4 batteries compare to other batteries, watch this test video: https://www.youtube.com/watch?v=aIy6S0TdSSE
Q: What happens when a LiFePO4 battery finds a short circuit?
A: LiFePO4 batteries hardly produce any sparks. The battery management system(BMS) can play a protective role.

5 kWh off-grid energy storage system for home use
Note: The premise is that the light conditions are sufficient 2,000W photovoltaic panel can fully charge aIn theory, a 5kWh energy storage system in about 3 hours.
Long-term solution
Despite the higher price, LiFePO4 batteries are characterized bymuch lower operating costs, which means that the purchase paysfor itself very quickly. Over its lifetime, a LiFePO4 battery costsmore than 100% less than a standard AGM battery, making it aworthwhile investment and a smart long-term solution.
