Overview:
The 51.2V 100Ah LiFePO4 battery pack is a high-voltage, high-capacity energy storage solution engineered for electronic power stations, off-grid solar systems, and residential/commercial energy storage (ESS). With a nominal energy of 5.12kWh, this battery leverages lithium iron phosphate (LiFePO4) chemistry to deliver exceptional safety, long cycle life (>6000 cycles), and stable performance under demanding conditions.
Its modular, stackable design allows for scalable capacity expansion—up to 15 units in parallel—enabling system configurations of over 75kWh, making it ideal for both backup power and full off-grid deployments.

Design & Safety Features
Modular & Stackable Architecture:
Designed for scalability, multiple units can be connected in parallel (up to 5–15 units depending on brand) to increase total energy capacity, supporting applications from 5kWh home backup to multi-kWh commercial systems.
Integrated Battery Management System (BMS):
The built-in BMS ensures cell balancing, state-of-charge (SOC) monitoring, and real-time fault detection. It supports remote monitoring via Bluetooth or CAN bus, enabling seamless integration with solar inverters and smart home energy platforms.
High Safety Profile:
LiFePO4 chemistry is inherently safer than NMC or LCO batteries, with higher thermal runaway thresholds (>200°C) and no oxygen release during thermal events. Combined with UL-94V0 flame-retardant casing and IP65 enclosure, it meets international safety standards for indoor and outdoor installations.
Wide Compatibility:
Designed to work with major hybrid and off-grid inverters (e.g., Growatt, Deye, Victron), the battery supports AC coupling, solar charging, and grid backup, making it a core component of modern all-in-one power stations.
Applications
Residential Backup Power: Powers essential loads (fridge, lights, Wi-Fi) during outages
Off-Grid Solar Systems: Stores solar energy for nighttime or cloudy-day use
Commercial & Industrial ESS: Supports telecom towers, remote monitoring stations, and small business operations
Portable Power Stations: Used in high-capacity mobile units for field operations or emergency response
Charging & Maintenance Guidelines
Recommended Charging Method: Use a CC/CV charger with MPPT solar controller or hybrid inverter set to 58.4V max charge voltage
Max Charging Current: 100A (1C) recommended; some models support up to 200A with dual MPPT inputs
Storage: Store at 50% SOC (≈51.2V) in a cool, dry place (15–25°C); recharge every 3–6 months
Avoid: Deep discharge (<44V), operation in extreme temperatures, or use without a compatible BMS-inverter handshake.
