FAQs

1. What is the safe charge and discharge voltage range?

Nominal voltage is 51.2 V, made from 16 cells (3.2 V nominal each).
Full charge (max) is 58.4 V → ~3.65 V per cell.
Discharge cutoff (min) is 40 V → ~2.5 V per cell 

2. What are the standard and maximum currents?

Standard charge/discharge: 50 A (≈ 0.25 C).
Max continuous charge/discharge: 100 A (≈ 0.5 C), only at temperatures ≥ 10 °C(51.2V-300Ah is 200A)
BMS will shut off charging/discharging beyond the limits.

3. Can I fast-charge this battery?

Fast charging within the design specs (up to 0.5 C) is acceptable. Going above can stress the battery, reduce cycle life, or trigger BMS protection 

4. What is the expected lifespan of this battery?

Rated at ≥ 6000 cycles at 80% depth of discharge and 25 °C. Typical lithium‑iron‑phosphate cells last 2,500–9,000+ cycles depending on use 

5. How do I monitor SOC and cell balance?

BMS performs passive balancing automatically when a cell hits ~3.40 V.
SOC LED indicators show ranges: 0–25%, 25–50%, 50–75%, ≥ 75%.
LCD shows voltage, current, temperature, and balance status.

6. Can 200A and 300A be connected in parallel?

No, the 300A is a newer product. Only units of the same model can be connected in parallel.
