LiTime 12V 50Ah Lithium LiFePO4 Battery 50A BMS, 10 Years Lifetime 4000+ Cycles Output Power 640W, Perfect for Boat Marine Camping Riding Mower (2 Packs)

【Similar Usable Energy but 5 Times Faster Charging】LiTime 12V 50Ah LiFePO4 lithium battery has 640Wh energy (12.8V×50Ah×100%DOD=640Wh ), which is close to the real energy of 12V 100Ah lead-acid battery (12V×100Ah×60%DOD=720Wh), as the depth of discharge (DOD) of lead-acid is about 60%. It means 12V 100Ah lead-acid battery can run an 80W load nonstop for 9hrs while 8hrs as our 12V 50Ah battery can. And it takes 10-20hrs to fully charge a 100Ah lead-acid battery while 1-2.5hrs of our battery. How efficient! 【Top Protection & 8 Times Lifespan】LiTime 12V 50Ah LiFePO4 battery is made of automotive grade LiFePO4 cells, which has higher energy density, more stable performance & built-in BMS. Compared with the 200-500 cycles and 3-year lifespan of lead-acid battery, LiTime battery has more than 4000 deep cycles and a 10-year lifespan, which means that the lifetime of one of our 12V 50Ah LiFePO4 battery is equivalent to the total lifetime of 3-8pcs 12V 100Ah lead-acid batteries. What a huge difference! 【4 Times the Value for Money】LiTime 12V 50Ah LiFePO4 battery ensures you 5-year warranty while the best-selling lead-acid battery is only 1 year. In terms of lifetime use, the value of our 50Ah battery is almost 4 times than 12V 100Ah lead-acid battery. For example, the cost per use of our battery is $0.069（$219.99/5-year warranty/640Wh=$0.069), but $0.294 of a 12V 100Ah lead-acid battery ($211.57/1-year warranty/720Wh=$0.294). Data shows that buying our battery is the best investment for your money. 【1/6*Lightweight & More Flexible Applications】LiTime 12V 50Ah LiFePO4 battery has an extremely lightweight of 11.57lbs, only 1/6 of a 12V 100Ah lead acid battery (about 60lbs), and a 10-year-old child may be easy to tow or move. Meanwhile, LiTime battery has various connections in parallel (max. capacity of 200Ah) and series (Higher voltage of 24V, 36V, 48V), it’s ideal for home back up system such as security devices, lights, solar and outdoor activities like boat, camping, trailer, etc. 【For Trolling Motor】LiTime 12V 50Ah battery is suitable for energy storage rather than start-up and supports a max. discharge current of 1C. Recommended: 12V 50Ah battery for 20~30lbs thrust trolling motor. (For recommendation on other models of trolling motors or starter batteries coming later this year, please feel free to contact LiTime.)
