BtrPower 2 Pack 12 Volt LiFePO4 Battery 12V 140Ah Batteries Pack for Solar Deep Cycle RV System

Battery specification Normal Voltage:  12.8V Normal Capacity:  140Ah Charge Voltege:  14.4-14.6V Cut-off Voltage:  10V Maximum Continuous Discharge Current:  100A Peak discharge current:  200A (Duration: less than 5 seconds) Standard charge current:  10A Over Charging Protection Voltage:  14.6V Cycle Life:  > 2000 cycles at 100% Depth of Discharge (DoD),up to 5000 cycles at 80% DoD Discharge Temperature:   -20℃~60℃ Charge Temperature:  0~45℃ Dimensions:  330*170*220mm/13*6.7*8.7in Weight:  15.45kg/34lbs Features of lithium iron phosphate battery:   [Long service life] The cycle life reaches more than 2000 times, and the standard charge (5 hour rate) use can reach 2000 times. The performance-price ratio will be more than 4 times that of lead-acid batteries. [Safe to use] Lithium iron phosphate has undergone strict safety tests and will not explode even in the worst traffic accidents.  [High temperature resistance] The peak value of lithium iron phosphate electric heating can reach 350℃-500 ℃, while lithium manganese oxide and lithium cobalt oxide are only around 200 ℃. [Green and environmental protection] Green environmental protection, regardless of production, use and scrap, does not contain or produce any toxic and harmful heavy metal elements and substances. [Low natural discharge rate] The self-discharge rate is very low, which is one of the most outstanding advantages of the battery. Generally, it can be less than 1%/month, less than 1/20 of the Ni-MH battery.    Safety&protection advantage:   [Built in Automatic Battery Protection System Internal] The intelligent,electric Battery Management System(BMS) protects batteries from extrem temperatures,overcharging,and excessive discharge,provide short circuit protection,balance voltage each cell.   Package List: 1x 12v 140Ah LiFePO4 Battery Pack (Charge and discharge from the same wires) This pack doesn't include the charger
