With 7.68kWh energy storage and a jaw-dropping 3000A peak discharge current, this industrial-grade lithium starter battery is the real deal when it comes to powering up diesel generators, heavy trucks, marine engines, and more.
This battery isn’t just powerful—it’s smart, rugged, and built to last. Featuring intelligent BMS, real-time Bluetooth monitoring, and wide-temp performance, it’s your go-to solution for high-current lithium applications.
Powerful Energy in One Compact Unit
With 300Ah capacity and a 24V system, this battery delivers up to 7.68kWh of clean, reliable power in a single pack. It’s ideal for RVs, marine systems, off-grid generators, and any application that demands both high output and dependable storage.
Thanks to its deep cycle lithium technology, you’ll get thousands of reliable cycles without the bulk or maintenance of traditional lead-acid batteries. Whether you’re cranking a diesel engine or running critical systems, this battery is built to go the distance.
Peak Current, No Compromises
When it comes to cold starts or power-hungry equipment, this battery doesn’t hold back. It can deliver up to 3000A peak discharge current (≤5 seconds), making it the perfect cold cranking lithium battery for:
- Diesel generator starting
- Heavy-duty truck ignition
- Marine engines in cold weather
- Industrial machinery requiring high current surge
And thanks to ultra-low internal resistance, even in sub-zero temperatures, it delivers smooth, reliable power where others fall short.
Advanced Active Balancing for Maximum Efficiency
Unlike passive systems that waste energy as heat, our smart BMS with active balancing redistributes energy across individual cells, keeping everything running smoothly and efficiently. This means:
- 95%+ energy utilization
- Longer overall battery life
- Enhanced safety and consistency
- Perfect for mission-critical applications like military and rescue vehicles
Whether you’re powering up a diesel gen-set or keeping a mobile command center operational, this battery stays balanced and efficient—even under stress.
Built-In Smart BMS with Bluetooth Monitoring
The most critical part of this lithium battery is its built-in intelligent energy management system.The integrated Battery Management System (BMS) monitors:
- Individual cell voltage (±3mV precision)
- Charge/discharge current
- Temperature and status data in real-time
- SOC (State of Charge), SOH (State of Health)
The Bluetooth-enabled app lets you view all this info on your phone—anytime, anywhere. Need more? Optional RS485, CAN, LCD display, or GPS add-ons offer even deeper integration with your system.
All-Weather Performance
Designed to operate in extreme conditions, this LiFePO4 cold weather starting battery handles:
- -20°C to +50°C working range
- Optional self-heating function for sub-zero starts
- Zero thermal runaway or early degradation
From icy mornings in the mountains to scorching heat in the desert, this battery won’t flinch. It’s a reliable power source for vehicles and equipment operating in the world’s toughest environments.
Built Tough for Industrial Use
Crafted to meet industrial standards and certified under UN38.3, CE, UL, ISO9001, this battery is engineered for:
- Marine environments (IP67-rated casing)
- Vibration-heavy applications like construction vehicles
- Dust, moisture, and shock resistance
- Long-distance logistics and rugged terrain transport
Whether installed on a yacht or a bulldozer, this is a true industrial-grade lithium battery built to perform—and to last.
Long Cycle Life = Long-Term Savings
Say goodbye to constant replacements. This 24V 300Ah deep cycle battery is rated for over 2000 full charge/discharge cycles, lasting 5x longer than comparable lead-acid models. It’s:
- Maintenance-free
- No memory effect
- Stable voltage over time
Over the years, it saves time, money, and hassle—making it a smart investment for fleet owners and power users alike.
