12.8V 300Ah 3840Wh Deep cycle battery pack1, High cycle life and excellent performance over a wide operating temperature.
2, LiFeO4 batteries are the safest lithium battery type currently available on the market today.
3, Featured with advanced battery management systems (BMS)
Lithium iron phosphate batteries (LiFePO4 or LFP) offer lots of benefits compared to lead-acid batteries and other lithium batteries. Longer life span, no maintenance, extremely safe, lightweight, improved discharge and charge efficiency. Due to a long life span and zero maintenance, it's the best investment you can make over time.


300ah deep cycle battery features:

Lithium iron deep cycle batteries are manufactured using automotive grade lithium iron phosphate batteries, which offer superior quality due to higher energy density, more stable performance and more power.

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

100% safe, non-toxic and renewable energy

Our 300ah deep cycle battery has a capacity of up to 300Ah, low self-discharge rate, low capacity loss, and is 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.

With 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.
