| Parameter | Value |
|---|---|
| Energy Density | 155 Wh/kg |
| Cycle Life (80% DoD) | 6,000 cycles |
| Self-Discharge Rate | 3% per month |
Advanced nickel-plated terminals enable low-resistance connections critical for high-current applications. The built-in hybrid BMS combines voltage balancing (±20mV accuracy) with active temperature compensation, maintaining optimal performance across -20°C to 60°C environments. When configuring battery banks, users should maintain less than 0.5V difference between parallel strings to prevent circulating currents.

How Does Temperature Affect Performance and Charging Protocols?
Below 0°C, charging currents must reduce to 0.05C (18A) with tapered absorption voltages. At 45°C ambient, derate discharge capacity by 8% per 10°C above 25°C. Winter storage requires 50% SOC at -10°C to prevent electrolyte viscosity issues. Built-in NTC thermistors trigger BMS throttling at ±5°C from optimal 15-35°C operational range.
| Temperature Range | Charging Efficiency | Discharge Capacity |
|---|---|---|
| -20°C to 0°C | 45% (with heating) | 65% |
| 25°C | 98% | 100% |
| 45°C | 92% | 88% |
Thermal management becomes crucial in stacked configurations. For every 10-cell series connection, maintain 8mm inter-cell spacing to facilitate air circulation. In extreme climates, consider liquid cooling plates that maintain 25-35°C cell temperatures, improving cycle life by 18-22%. The BMS automatically engages cell heating below 5°C using internal resistive elements, consuming 2-3% of pack capacity daily.
“This battery’s UL-certified cell spacing design reduces thermal crosstalk by 40% compared to standard prismatic modules. The nickel-plated terminals resist saltwater corrosion up to 500 hours in ASTM B117 testing – critical for marine applications. Our stress tests show 92% capacity retention after 2,000 cycles at 100% DoD with 1C discharge rates.”

FAQs
- Can I connect these batteries to existing lead-acid systems?
- No – voltage curves and charging profiles differ significantly. Use dedicated LiFePO4-compatible charge controllers to prevent under/overvoltage damage.
- What certifications does this battery hold?
- CE, RoHS, UL 1973, IEC 62619, and UN38.3 for air transport. The cells meet GB/T 36276-2018 standards for cycle life validation.
- How does altitude affect performance?
- Operational up to 5,000m elevation. Above 2,000m, derate maximum continuous current by 1% per 100m due to reduced convective cooling.
