The 25.6V 314Ah LiFePO4 battery — 8.04kWh from an 8S1P pack — is the 24V-class answer to high-capacity mobile and off-grid storage. It halves the current of an equivalent 12V system, cutting cable losses and allowing smaller wiring, while keeping the system voltage familiar to RV, marine, and off-grid installers. This page covers the specification, cell options, BMS choices, and wholesale/OEM sourcing.

Market naming: sold as “24V 314Ah” or an “8kWh LiFePO4 battery”. The technical voltage is 25.6V (8S); “24V” is the market name.
Cell Options
Built from the 314Ah prismatic generation — EVE MB31, REPT, Hithium, CATL, CALB, Gotion. The 8S1P arrangement is a standard, well-understood structure: eight cells in series, no parallel strings, which simplifies cell matching and long-term balance. LJY Energy verifies cell model, grade, and batch documentation per project; UN38.3 test summaries and MSDS are supplied for shipped goods. Specifications, pricing, MOQ, and lead times are confirmed per project.
Applications
- RV and motorhomes (24V systems): 8kWh supports air conditioning, induction cooking, and full off-grid living. 24V halves current vs 12V, so a 3kW inverter draws ~125A instead of ~250A.
- Marine and yachts: house banks for 24V onboard systems; IP67 options for bilge-adjacent installation.
- Off-grid cabins and telecom-adjacent sites: pairs with 24V inverters and MPPT controllers for 2–4kW solar arrays.
- Trucks and work vehicles: 24V auxiliary power matching the vehicle’s native electrical system.
The same cell generation is available at other voltages: 12.8V 314Ah (4.0kWh) for 12V systems and 51.2V 314Ah (16.1kWh) for home storage. For cell-level sourcing, see LiFePO4 battery cells wholesale.
BMS and Customization Options
- Bluetooth BMS: app monitoring of voltage, current, SOC, and cell temperatures — see our BMS selection guide.
- Communication BMS: CAN/RS485 for inverter integration.
- High-current BMS: up to 300A continuous for large inverter loads.
- Low-temperature protection: charging cut-off below 0°C; self-heating options for cold climates.
- Waterproofing: IP65/IP67 enclosures for marine and outdoor installation.
- OEM branding: private-label cases and specification sheets.

Why 24V Makes Sense at 8kWh
- 3kW inverter at 12V: ~250A — requires 70mm²+ cable and heavy-duty fusing.
- 3kW inverter at 24V: ~125A — standard 35mm² cable, simpler and cheaper installation.
24V is also the native voltage of many trucks, marine systems, and larger RVs. For systems above ~5kWh, 24V is the practical minimum; above ~15kWh, move to 48V (see our 51.2V 314Ah page).
Shipping, Documentation & Project Terms
Lithium batteries ship as Class 9 dangerous goods with UN38.3 test summaries and MSDS. Specifications, pricing, MOQ, and lead times are confirmed per project.
Frequently Asked Questions
Why choose 24V over 12V for an 8kWh system?
At the same power, 24V halves the current: a 3kW inverter draws ~125A at 24V vs ~250A at 12V. That means thinner cables, less voltage drop, and lower heat.
How much energy does 25.6V 314Ah hold?
25.6V × 314Ah = 8,038Wh (8.04kWh) — enough for a full day of typical RV or off-grid cabin use.
Is it compatible with my 24V inverter?
Most 24V inverters and MPPT controllers accept the 25.6V nominal / 29.2V charge profile. With a CAN/RS485 BMS, it can communicate with compatible inverter brands — confirm the protocol per project.
Can I parallel multiple units?
Yes, within the BMS manufacturer’s limits. Two units give 16kWh; four give 32kWh. For larger home storage, consider the native 51.2V 314Ah model.
