Check the listing for details. 12V LiFePO4 battery 140Ah lithium Battery for RV Deep Cycle Solar Marine System. Color: Black, Condition: New. Listed at 226.99 USD. 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 Precautions: It is recommended to charge up the battery to 80% if you are going to store it for a period; Make sure the battery will be charged at least once every 3 months to ensure the best performance and cycle life; The battery should be stored in a dry environment, keep away from fire and heat sources; Avoid direct connection of positive and negative poles.
