What Are the Features of EG4 LiFePower4 V2 48V 100Ah Battery?
The EG4 LiFePower4 V2 48V 100Ah is a lithium iron phosphate (LiFePO4) battery system engineered for high-efficiency energy storage, delivering 5.12kWh capacity. Key features include a 100A BMS for overcurrent/thermal protection, IP65-rated rugged casing, and compatibility with solar/off-grid setups. Its modular design allows parallel expansion up to 16 units (81.92kWh total), while touchscreen monitoring and Bluetooth app integration provide real-time voltage, temperature, and cycle tracking. Rated for 5,000+ cycles at 80% DoD, it supports continuous 4.8kW loads. PM-LV48100 Pro 3U
What makes the EG4 LiFePower4 V2 suitable for solar systems?
Its wide voltage range (40–58.4V) and 4.8kW continuous output enable seamless integration with hybrid inverters. The battery’s passive balancing system maintains cell stability during irregular solar charging, while its 98% round-trip efficiency minimizes energy waste. Pro Tip: Use EG4’s CANbus communication protocol for synchronized charge/discharge rates with solar controllers.
How does the built-in BMS enhance safety?
The 100A BMS monitors all 16 LiFePO4 cells, implementing 12 safeguards like overvoltage cutoff (58.4V) and low-temperature charge blocking (≤23°F). Unlike basic 48V packs, it uses tiered alerts—first reducing power at 90% fault severity before full shutdown. For example, a loose cell connection triggers a 50% output reduction, allowing emergency backup during diagnostics.
| Parameter | EG4 V2 | Standard 48V |
|---|---|---|
| BMS Current | 100A | 50–80A |
| Cycle Life | 5,000+ | 3,000 |
Can the EG4 V2 support high-power motors?
Yes—its 5-second 200A surge rating (10kW peak) handles induction motor startups in RVs or marine applications. The nickel-plated terminals resist corrosion from high-current arcs, maintaining <0.5mΩ impedance after 10,000 connection cycles. Pro Tip: Pair with EG4’s 48V-to-12V DC converter for auxiliary systems without voltage drops.
What communication interfaces does it offer?
Beyond Bluetooth, the EG4 V2 includes RS485, CAN 2.0B, and dry contact ports for integration with Schneider or Victron inverters. The proprietary protocol auto-adjusts charge curves—solar priority modes reduce grid dependence by 30% compared to standard lithium batteries. For example, during cloudy days, it extends absorption phases to maximize PV harvest.
| Interface | Function |
|---|---|
| RS485 | Multi-battery synchronization |
| CANbus | Inverter compatibility |
How does its cycle life compare to lead-acid?
The LiFePO4 chemistry delivers 5–7× longer lifespan—6,000 cycles at 80% DoD versus 800 cycles for AGM. Depth-of-discharge tolerance is key: discharging to 20% SOC daily causes only 0.005% capacity loss/month. Practically speaking, a solar system using EG4 V2 pays back in 3.2 years vs. 5.1 years for lead-acid alternatives.

FAQs
Yes—its voltage range (40–58.4V) supports 48V nominal systems and 51.2V lithium-compatible inverters. Use the CANbus interface for automatic voltage calibration during first-time setup.
Can I charge it via generator?
Absolutely, but enable “Generator Mode” in the app to limit charge current to 50A, preventing fuel waste from generator surge loads.
