Core advantages

Power That Goes the Distance

7.168kWh of deep-cycle energy, made for off-grid life

When you’re off the grid, every amp-hour matters. This high-capacity 24V lithium battery for solar storage can run your essentials—like a fridge, lights, fans, and inverter—for days on a single charge. Whether it’s an RV road trip, a remote work site, or an off-grid home, you’ll experience fewer recharges and longer runtime.

Need more capacity? Simply connect multiple units in parallel to scale beyond 10kWh, creating a flexible solar battery bank for heavy loads or longer runtimes. It’s an ideal energy storage solution for solar systems, backup power, or anywhere you need serious capacity with low maintenance.

Built to Start What Others Can’t

Reliable cold-crank power for generators, trucks, and more

This isn’t just a solar battery—it’s a powerhouse starting battery too. With a built-in 200A BMS and high-discharge LiFePO4 cells, the Anengji 24V 280Ah battery delivers strong startup current to fire up diesel generators, heavy-duty trucks, or construction machinery with ease.

Traditional lead-acid batteries fade with time and temperature. Our cold weather battery performance holds steady, offering consistent starts even in freezing conditions. If you’re looking for the best lithium battery for generator start, this one delivers every time.

Smarter Battery, Safer Energy

Advanced BMS + Bluetooth for peace of mind

A smart system starts with a smart battery. This unit comes with a dual active balancing system, maintaining voltage uniformity across all cells without wasting energy. That means longer lifespan, better performance, and more efficient charging—ideal for long life lithium battery setups.

The built-in Battery Management System (BMS) provides full protection against overcharging, over-discharging, short circuits, overheating, and reverse polarity. Each cell is monitored with ±3mV precision, ensuring your system stays safe and stable in real-world conditions.

Ready for the Elements

IP67-rated housing and wide temp operation

This battery isn’t scared of the outdoors. Thanks to a rugged IP67-rated case, it’s fully dustproof and protected against splashes and brief submersion. It’s perfect for mounting in a vehicle, golf cart, camper trailer, or exposed outdoor equipment rack.

Operating in harsh environments? No problem. It performs reliably from -20°C to 50°C, making it the go-to lithium battery for outdoor power systems in snow, rain, or desert heat. It’s also available with self-heating for cold-climate use and CAN/RS485 communication options for full system integration.

Stay Connected Anywhere

Real-time monitoring with your smartphone

The built-in Bluetooth battery monitoring app makes it easy to check your system status. Monitor state of charge (SOC), health (SOH), voltage, current, temperature, and more—all from your phone.

Want more control? Optional RS485 or CAN interfaces allow seamless integration with solar inverters, vehicle ECUs, and other smart energy components. Add an external LCD display for on-site readings. It’s a complete solution for remote monitoring and smart energy management.
