12.8V 300Ah 3840Wh Deep cycle battery pack

300ah Deep cycle batteries are commonly used in RV and marine solar systems. There are different types of deep cycle batteries, plug-in deep cycle battery alternatives for recreational vehicles, off-grid solar applications, boats, trolling motors, etc., suitable for maximizing energy storage and power requirements

With overcharge, overdischarge, overcurrent and short-circuit protection and high self-discharge rate.

100% safe, non-toxic and renewable energy. 

Our lithium iron deep cycle batteries has a capacity of up to 300Ah, low self-discharge rate, low capacity loss, and 40% stronger than lead-acid batteries of the same size (lead-acid batteries have a depth of discharge of about 60%).

Efficient charging and easy installation

Suitable for off-grid solar system and outdoor home backup power, RV, camping, sailing and other applications.

Large capacity, you don't have to worry about not being able to charge the battery on cloudy days because the battery's extra long life will give you reliable power or longer, more enjoyable trips.

Smaller size, LiFePO4 batteries are smaller and 1/3 the weight of lead-acid batteries of the same capacity, making them easy for you to disassemble and place.

Compared to the 200-500 cycles and 3-year life of lead-acid batteries, our rechargeable batteries provide more than 4,000 cycles (10 times longer) and a 10-year life. This is 2000-3000 cycles longer than other LiFePO4 batteries on the market.
