About This 【Light Weight & Group 31 Design】 Timeusb lithium battery 12V 140Ah has a high energy density of 64.23Wh/lb. It weighs just 27.9lbs, which is 1/2 the weight of a 12V 100Ah lead-acid battery at 55lbs. The Timeusb 12V 140Ah Group 31 LiFePO4 battery has the same size as the Timeusb 12V 100Ah Pro Group 31 LiFePO4 battery, but with an additional capacity of 40Ah, providing longer endurance. With its compact size of L13*W6.77*H8.43 inches and M8-5/16"(16mm) terminal bolts,it helps save more space. Please note that these 2-pack batteries come in 2 packages and may arrive on different days 【Upgraded BMS with Low Temp Cut Off & Advanced Grade A Cells】 Timeusb 12V 140Ah LiFePO4 battery is built-in 100A advanced BMS to protect it from over-charging, over-discharging, overcurrent, short circuit, high-temperature. Low Temp cut off function will automatically cut the battery off from charging when the cell temperature is lower than 32℉. The 12V 140Ah lithium battery adopts automotive-grade battery cells in an ideal battery cell structure allowing it to perform up to 15000 deep cycles. 【Max.1792Wh Energy Output & Max.4P4S Expansion】 Timeusb 12V 140Ah LiFePO4 lithium battery is UL/FCC/CE/ROHS certified and has a 100% reliable capacity. It can achieve 100% SOC and 100% DOD, built-in 100A BMS board supporting Max.100A charge/discharge current and Max.1280W load power. Using 16 lithium iron phosphate batteries to be connected to Max.4P4S to form a 51.2V 560Ah system can achieve Max.28.672kWh energy storage and Max.20.480kW load power. 【Widely Used】 Timeusb 12V 140Ah LiFePO4 battery is designed as an energy storage battery, it can be used in the following areas: Home energy storage systems, RVs, Campers, Trailers, up to 70lbs Trolling motors, e-Robots. However, this 12V 140Ah deep cycle battery can't be used to start any engines in vehicles, like Golf Carts and automobiles. 【Green Energy & Higher Safety】 The Timeusb 12V 140Ah lithium battery is 100% green energy, manufactured all materials that make up the battery is stable and harmless. It can be cycled up to 15000 times which are 3 times the number of AGM cycles, reducing battery replacement frequency and resource waste. LiFePO4 battery is more stable in chemical structure with lower risk of leaking and better temperature performance, which makes it safer than AGM battery.
