WattCycle 12V 50Ah LiFePO4 Lithium Battery with Built-in 50A BMS,Max. 640Wh Energy Deep Cycle Battery,Ideal for Trolling Motor, RV, Wheelchair, Camper, Off Grid

• [1/6*Lightweight & Flexible Applications]WattCycle 12V 50Ah LiFePO4 battery has an extremely lightweight of 11.4lbs, 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,for outdoor activities like weeding, fishing, camping and trailer, and for some power systems such as wheelchairs.

• [100% Safe & Built-In 50A BMS]WattCycle LiFePO4 12V 50Ah batteries are made of A-grade LiFePO4 cells, featured as their high energy density, environmentally friendly, stable voltage performance, high safety level; built-in 50A BMS, which could support 50A max. continuous charge/discharge current, 640W max. load power, and can protect the battery from over-charge, over-discharge, over-current, and short circuits. And also built-in high-temp cut-off prevents charging over 122 °F (50 °C).

• [Similar Usable Energy but 5 Times Faster Charging]WattCycle 12V 50Ah LiFePO4 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 lithium battery can do. And it takes 10-20hrs to fully charge a 100Ah lead-acid battery while 1-2.5hrs of lithium battery.

• [8X Cycles Times & 3 Times Service Life]WattCycle12V 50Ah LiFePO4 battery has 6000+ deep cycles & a 10-year lifespan, while lead-acid battery only has 200-500 cycles & a 3-year lifespan. In terms of the lifetime, one pcs WattCycle 12V 50Ah LiFePO4 battery is equivalent about 3-8pcs 12V 100Ah lead-acid battery. An example for you: per-use of a WattCycle 12V 50Ah lithium battery costs $0.05($203/4000cycles≈$0.05). A 100Ah lead-acid battery costs about $0.42 to $1.05 for per-use ($211/200-500cycles≈$0.42 to $1.05).
