Features
【Half Lightweight And Twice Capacity】 LiFePO4 battery weighs only 6.3kg, only half weight and providing twice capacity in the same size as lead-acid batteries, you can easy to move and install. And our LiFePO4 battery is 100% usable capacity compared with lead-acid battery only provide 60%~70% capacity.
【BUILT-IN BMS & Fast Charging】Lithium battery builds in BMS, which can prevent the LifePO4 battery from the most common issue causing of battery failure, such as overcharge, over-discharge, over-current and short circuit. battery fast charging time when charging by 12.8V 50Ah LiFePO4 battery charger, saving time in charging compared with lead-acid battery which needs 10 hours charging time to around 70% capacity.
【Save your money】 lifepo4 battery provides 2000+ deep cycle times, , which is far beyond than lead acid battery with 300-500 cycle times . Although lifepo4 battery is a little more expensive than lead-acid batteries, the lithium battery has longer lifespan and cycle times, the average cost of use is lower. Therefore, lithium battery help you to save more money.
【Eco-Friendly Energy 】 Our LiFePO4 batteries are widely used for solar system, RV trip and outdoors activities, you could enjoy self-reliant colorful life when using the battery in solar source.
【3-Year Warranty 】We do our best to provide the safest battery and the most professional service to every customer.
