? Frequently Asked Questions
Q What battery type is used in this product?
This product uses a LiFePO4 (Lithium Iron Phosphate) battery, which is known for its excellent thermal stability, long cycle life, and enhanced safety compared to other lithium battery chemistries.
Q What is the maximum input charging current supported?
The typical maximum input charging current is 80A. It is important not to exceed this rating to ensure safe and reliable charging operation.
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.
Q What does "20S" battery link configuration mean?
20S means 20 battery cells are connected in series. This series configuration increases the overall voltage of the battery pack while maintaining the same capacity as a single cell.
Q What is the continuous output discharging current limit?
The continuous output discharging current must be kept at ≤ 120A. Exceeding this limit may cause overheating or damage to the battery management system and connected components.
Q How is the input charging voltage calculated for different battery types?
The charging voltage depends on the battery chemistry and number of strings: for Triple (Ternary Lithium) batteries, it is 4.2V × string count; for LiFePO4 batteries, it is 3.65V × string count. For a 20S LiFePO4 configuration, this equals 73V maximum charging voltage.
