Replace bulky 24V lead-acid battery banks with one high-capacity LiFePO4 power unit.

With 314Ah and 8.04kWh of stored energy, this 24V battery is built for compatible heavy-duty vehicles that need both starting support and auxiliary power.

Power essential auxiliary loads while parked — without running the engine every time.

Use stored lithium energy for lights, fans, mini fridge, tools, electronics, and inverter-powered devices. It helps reduce unnecessary idle time, noise, and fuel use in compatible 24V systems.

200A Continuous Output & 8038Wh Stored Energy

Up to 5.1kW DC output for demanding auxiliary power systems. 314Ah capacity supports parked cab loads, electronics, lighting, fans, fridge, and inverter-powered devices.

Bluetooth Monitoring

Built-in Bluetooth allows you to check key battery data directly from your phone. You can monitor state of charge, voltage, temperature, working status, and system alerts without opening the battery compartment.

Compact & Flexible Installation

With a size of 20.63 × 14.37 × 9.15 inches, this battery is designed for flexible installation in truck and mobile power systems. It may fit in areas such as frame rail spaces, under-bunk compartments, behind-cab areas, or custom auxiliary battery setups, depending on the vehicle.

Tested Performance + Reduce Idle Time

For a dual-purpose truck battery, real-world performance matters. Cold cranking tests, diesel engine start tests, voltage drop data, peak current results, and low-temperature performance help verify reliability, while stored lithium energy helps drivers reduce unnecessary idling, save fuel over time, and enjoy quieter rest periods when powering basic cab loads.

Built for Multiple Applications

This battery is primarily designed for semi truck starting and sleeper cab power, but it can also support RVs, utility vehicles, off-grid systems, and custom mobile power setups. For best performance, always match the battery with the correct installation, charging method, and load requirements.

FAQ

This battery is suitable for compatible 24V trucks, heavy-duty vehicles, emergency vehicles, special work vehicles, RV power systems, and off-grid setups. It is not recommended for standard 12V vehicles.

Yes. This 24V LiFePO4 battery is rated for 1800A Cold Cranking Amps, helping provide strong starting support for compatible 24V heavy-duty vehicle systems.

Yes. With 314Ah capacity and 8.04kWh of stored energy, it can help power essential onboard loads such as lights, fans, mini fridge, electronics, and inverter-powered devices. Actual performance depends on inverter size, wiring, load demand, temperature, and system setup.

It can be used as a lithium upgrade for compatible 24V systems, but it is not a universal drop-in replacement for every lead-acid setup. Please confirm your charging system, wiring, mounting space, and load requirements before installation.

Use a 29.2V LiFePO4-compatible charger. Many lead-acid chargers do not have the correct lithium charging profile, so always confirm charger compatibility before use.

Yes. The battery supports self-heating and has low-temperature charging protection. Do not charge the battery below 32°F / 0°C unless the self-heating system and charging conditions are properly supported.

It can be used in compatible 24V RV or custom mobile power systems, especially where higher-capacity lithium storage is needed. For standard 12V RV systems, a 12V LiFePO4 battery may be a better fit.
