LiTime 12V 50Ah LiFePO4 Lithium Battery, Build-in 50A BMS, 640Wh Energy

* Similar Usable Energy but 5 Times Faster Charging: The LiTime 12V 50Ah LiFePO4 battery offers 640Wh of energy, making it comparable to the real energy output of a 12V 100Ah lead-acid battery (which provides 720Wh at 60% depth of discharge). This powerful lithium battery enables nonstop running of an 80W load for 8 hours, just as a 12V 100Ah lead-acid battery would. However, the lithium battery can be fully charged in just 1-2.5 hours, whereas a 100Ah lead-acid battery requires 10-20 hours for a full charge. * Top Protection & 8 Times Lifespan: The LiTime LiFePO4 battery is composed of automotive grade LiFePO4 cells, which offer a higher energy density and more reliable performance. Unlike lead-acid batteries that typically last for 200-500 cycles and have a lifespan of around 3 years, LiTime lithium battery can endure more than 4000 deep cycles and has a lifespan of 10 years.  * 4 Times the Value for Money: LiTime LiFePO4 battery ensures you a 5-year warranty while the best-selling lead-acid battery is only 1 year. In terms of lifetime, the value of our 50Ah lithium iron phosphate battery is almost 4 times than 12V 100Ah lead-acid battery. For example, the cost per use of our LiFePO4 battery is $0.069, but $0.294 for a 12V 100Ah lead-acid battery . Data shows that buying our lithium battery is the best investment for your money. * 1/6*Lightweight & Flexible Applications: LiTime 12V 50Ah LiFePO4 battery has an extremely lightweight of 11.57lbs, only 1/6 of a 12V 100Ah lead acid battery, and may be easily moved by a 10-year-old child. Meanwhile, our lithium battery supports 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 weeding, fishing, camping, trailer, etc. * Fast Delivery & Outstanding Service: LiTime commits to providing you with satisfactory service. Fast delivery because the battery will be shipped from our  local warehouse in NSW.  (Generally, the delivery will take less than 5 days, a few distant cities will take 1-2 weeks.) Professional technical support, humanized return policy & customer service as we provide easy-to-understand operation manuals & online services with quick feedback within 24hrs. If you have any questions, please feel free to contact us, we will do our best to support you. * For Trolling Motor: This 12V 50Ah LiFePO4 battery is suitable for energy storage rather than start-up and supports a max. discharge current of 1C. Recommended: 12V 50Ah LiFePO4 battery for 20~30lbs thrust trolling motor. (For recommendations on other models of trolling motors or starter batteries coming later this year, please feel free to contact LiTime.)
