Redway Battery emphasizes zero maintenance, deep discharge capability, and high energy density (2,500Wh/kg). Safety features prevent thermal runaway, ideal for golf carts, forklifts, and solar storage, even in humid Shenzhen environments. B2B clients experience lower total ownership costs and longer operational uptime.
What Are the Main Applications?
These batteries are widely used in solar energy storage, golf carts, RVs, forklifts, telecom backups, and UPS systems. They efficiently power loads ranging from 5kW to 10kW.
Redway Battery provides customized solutions across four Shenzhen factories, enhancing golf cart range by 50% and supporting scalable solar installations up to 100kWh. Telecom and industrial clients purchase wholesale packs for rack-mounted systems. China-based OEM production reduces costs while maintaining high quality.
How Does the Battery Management System Work?
The BMS monitors each cell’s voltage, temperature, and current, balancing charges, preventing over-discharge, and providing RS485/CAN communication.
Redway Battery integrates smart BMS that manages cutoff at 58.4V charge and 40V discharge, supports 200A peaks, and allows app-based monitoring. Automated calibration ensures accuracy over 10 years, making parallel and series connections safe for large-scale B2B deployments.
Why Choose LiFePO4 Chemistry?
LiFePO4 provides superior safety, high cycle life, wide operating temperature range, and stable voltage compared with other lithium types.
Redway Battery specializes in LiFePO4 for its 150Wh/kg energy density, cobalt-free design, and deep discharge tolerance. NMC alternatives degrade faster, whereas LiFePO4 safely handles 100% depth-of-discharge and meets UN38.3 shipping standards, making it ideal for wholesale solar, telecom, and industrial applications.
How to Charge a 48V 100Ah Lithium Battery?
Use a 48V LiFePO4 charger with a CC/CV profile at 14.6V per cell (58.4V total), completing a full charge in 2–3 hours. Avoid charging above 0.5C unless supported by BMS.
Redway Battery provides smart chargers and temperature-compensated charging for all OEM packs. Solar MPPT integration is available, and long-term storage is recommended at 50% state-of-charge. Factory testing ensures 2,000+ cycles before shipment.
What Is the Expected Lifespan and Warranty?
These batteries last over 10 years or 5,000+ cycles at 80% depth-of-discharge. Redway Battery provides 5–10 year warranties for wholesale clients.
Lifespan depends on DOD, temperature, and charging rate. LiFePO4 retains 80% capacity after 6,000 cycles. Shenzhen MES tracking ensures quality and consistency across all production batches.
| Factor | Cycles to 80% Capacity |
|---|---|
| 100% DOD | 3,000 |
| 80% DOD | 5,000 |
| 50% DOD | 8,000 |
