💬 Frequently Asked Questions
Q
What type of battery chemistry does this product use?
This product uses LiFePO4 (Lithium Iron Phosphate) battery chemistry, which is well-known for its excellent thermal stability, long cycle life, and enhanced safety compared to other lithium-ion chemistries.
Q
What is the maximum input charging current supported?
The typical maximum input charging current is 80A. Exceeding this value may affect battery performance and safety. Always ensure your charger is rated appropriately.
Q
What is the recommended input charging voltage for LiFePO4 configuration?
For the LiFePO4 configuration, the input charging voltage is calculated as 3.65V × String count. For a 20S configuration, this equals 73V. For Triple (ternary lithium) configurations, it is 4.2V × String count.
Q
What is the output discharging voltage range?
The output discharging voltage ranges from a minimum of 46V to a maximum of 74V, with a typical operating voltage of 64V. This wide range ensures compatibility with various application requirements.
Q
What is the continuous output discharging current limit?
The continuous output discharging current is rated at ≤ 120A. The system supports a maximum output discharging current of 120A, and sustained operation should remain within this limit to ensure longevity and safety.
Q
What does the "20S" battery link configuration mean?
The 20S configuration means 20 battery cells are connected in series. This series connection increases the total voltage of the pack. For LiFePO4 cells at 3.2V nominal, a 20S pack delivers approximately 64V nominal voltage, which aligns with the typical output discharging voltage specified.
