What Is The 48V 4X EAGLE KIT LiFePO4 120Ah 6.14kWh?
The 48V 4X EAGLE KIT LiFePO4 120Ah 6.14kWh is a high-capacity lithium iron phosphate battery system designed for demanding applications like solar storage, electric vehicles, and off-grid power. It combines four 12V LiFePO4 modules in series to achieve 48V nominal voltage, delivering 6.14kWh energy storage with UL1973/IEC62619 certifications. The modular design enables scalability up to 300kWh through parallel connections, while its smart BMS ensures thermal stability, cell balancing, and >6,000-cycle durability.
How is the 4X configuration structured?
This system uses four 12V LiFePO4 modules (≈12.8V each) in series to reach 51.2V total—higher than nominal 48V—explaining its 6.14kWh capacity (51.2V × 120Ah). Cell matching and bus bar connections maintain voltage consistency across modules.
Practically speaking, series wiring amplifies voltage without increasing current draw. Each 12V block contains 4×3.2V LiFePO4 cells internally, with reinforced interconnects resisting vibration in mobile applications. Pro Tip: Always commission all modules simultaneously—mixing old/new units creates imbalance, reducing lifespan by 15–25%. For example, mismatched internal resistances in a golf cart battery pack could cause premature BMS shutdown during acceleration.
| Connection Type | Voltage | Capacity |
|---|---|---|
| Series (4×12V) | 48V | 120Ah |
| Parallel (4×120Ah) | 12V | 480Ah |
What safety features does the BMS include?
The integrated battery management system monitors voltage/temperature per cell block, implementing multi-layer protection against overcurrent (≥150A cutoff), deep discharge (<10% SoC), and thermal runaway (>60°C disconnects).
Beyond basic protections, it uses active balancing during charging to redistribute energy between cells—critical when charging at 1C rates. Why does this matter? A 0.5V imbalance in a 48V pack reduces usable capacity by 18%. The BMS also logs fault codes, aiding diagnostics. Pro Tip: For solar installations, pair with a 58.4V CC-CV charger to avoid tripping the 3.65V/cell overcharge protection.

FAQs
Yes, but verify motor controller compatibility—some OEM systems require exact 48.0V input. The pack’s 51.2V working voltage may trigger overvoltage alerts in older carts without LiFePO4 modes.
Is professional installation required?
Mandatory for grid-tied systems due to NEC 705.12 interconnection rules. DIY allowed for off-grid setups if using factory bus bars and torque specs (typically 5–8 N·m).
What’s the real-world lifespan?
6–12 years depending on cycling depth—6000 cycles at 80% DoD vs 12000+ at 50%. Storage below -40°F permanently damages cells; maintain ≥20% charge when idle.
