Powerful Lithium Storage for Off-Grid, RV, and Golf Cart Life

This 24V 300Ah lithium battery kit (two 12V 300Ah units) is perfect for RV owners, off-grid builders, solar setups, and golf cart users who need long-lasting, safe, and lightweight energy storage. Designed with upgraded LiFePO4 cells and a built-in 200A BMS, it provides up to 10,000 cycles—delivering reliable, high-capacity power wherever you need it.

What’s Included

Here’s what’s included with this product:

• 2 × 12V 300Ah LiFePO4 Batteries (24V system when combined)
• Each unit includes built-in 200A BMS
• High-efficiency Grade A LiFePO4 cells
• Customer support with 5-year warranty

Key Benefits

What makes this product a great choice:

• Delivers 6.14kWh of usable energy (3.84kWh per battery)
• Each battery weighs just 56 lbs—⅓ the weight of a comparable lead-acid unit
• Lasts up to 10,000 cycles with proper usage
• Built-in 200A BMS offers full protection against overcharge, temp, and short-circuit
• Expandable in up to 6S or 6P configurations for higher power or voltage
• Compact footprint fits RV bays, golf carts, campers, and solar banks

Our Verdict

If you're switching to lithium for long-term power reliability, the E-LekTech 24V 300Ah battery kit makes the transition easy. Each 12V unit is compact and light, yet packed with efficient, automotive-grade LiFePO4 cells. The result? Serious off-grid energy in a form that’s easy to handle and install.

Whether you're powering an RV, cabin, golf cart, or solar array, this kit covers multiple needs. The 200A BMS in each battery adds protection where it matters, shielding against voltage spikes, extreme temperatures, and current overload. That kind of safety is essential for mobile and stationary power alike.

We like how easy it is to scale the system. You can connect up to six batteries in series or parallel, allowing you to build larger capacity banks over time without replacing your entire system. That makes it ideal for long-term projects where flexibility and growth matter.

The 10,000-cycle lifespan also makes it a long-haul investment. That’s a potential decade of power, with minimal maintenance and no sulfation issues like you’d get from lead-acid. It’s greener, safer, and much lighter—saving weight and space in mobile setups.
