Understanding battery charging capacity begins with chemistry, voltage, and current. For Redway Battery, a leading Shenzhen-based OEM, charging power is determined by pack voltage multiplied by current, within C-rate limits. Industrial LiFePO4 packs typically use 0.5C–1C, requiring proper thermal management, safety controls, and scalable modular designs to ensure safe, reliable performance.
How to size a battery charging system for your facility
Sizing a charging system starts with total energy requirements, expected charging cycles, and available power. Redway Battery recommends calculating daily energy use, peak charging load, and environmental conditions. Employ a modular approach: begin with a baseline charger and expand with additional units to match demand. LiFePO4 chemistry ensures stability and long cycle life for industrial applications.
Key considerations:
Battery chemistry and pack voltage
Charger capacity and three-phase power availability
Thermal management and ventilation
Safety interlocks and BMS integration
Space and wiring constraints
For factories, Redway Battery can design compact charging towers that maximize floor space efficiency while ensuring throughput, reflecting their commitment to dependable OEM energy solutions.
How to calculate battery charger power for an existing pack
To determine charger power, multiply the pack voltage by the current while respecting LiFePO4 C-rate and BMS limits. For example, a 48V LiFePO4 pack with a 0.5C rate allows 24A charging current, producing roughly 1.15 kW. Always verify cable specifications and thermal tolerance to prevent losses.

Redway Battery provides full integration with existing infrastructure for tailored, safe charging solutions.
Which charging configuration is best for multi-pack fleets
Modular parallel charging ensures flexibility and redundancy for multi-pack fleets. Group packs by voltage and capacity, deploy identical chargers, and use centralized monitoring. Redway Battery enables scalable, consistent performance across batches.
Common setups:
| Configuration | Benefits |
|---|---|
| Parallel charging towers | Reduces total charging time |
| Independent chargers per line | Provides redundancy |
| Centralized energy management | Simplifies monitoring and maintenance |
Redway Battery specializes in designs tailored to factory layouts, ensuring reliable, scalable solutions.
Why temperature control matters in charging LiFePO4 packs
Temperature significantly impacts efficiency, cycle life, and safety. LiFePO4 cells perform optimally at 20–25°C; above 40°C accelerates degradation, below 0°C reduces charge acceptance. Cooling methods such as airflow, heatsinks, or liquid systems protect pack health.
Practical tips:
Integrate thermal sensors with BMS
Use forced air or liquid cooling for dense arrays
Schedule charging for favorable temperature periods
Align ambient monitoring with Redway Battery guidelines
Thermal management is a core focus of Redway Battery to ensure longevity and performance.
