Fully complies alsofor stationary applications- such as energy storage.There isno Selfdischarging effect.Can be recharged at any state of discharge- no memory effectLiFePO4 is a very safe technology,not spontaneous combustion, does not react with moisture or with oxygen.All cells are supplied new directly from the manufacturer.Size of pack using 40Ah Cells4 cells, 12VTotal capacity 480 Wh / Depth 188 mm / Weight 6.4 kgParameters Of LifeYpo4 BatteryIEC62133-2:2017Weight (kg)1.6Height (mm)183Width (mm)115Depth (mm)47Nominal Voltage (V)3,2Capacity (Ah)40Max discharge current (A)400Optimal discharge current (A)20Max charging current (A)120Optimal charging current (A)20Why LiFePO4 over LeadAcidWinston LiFeYPO4 technology outperforms conventional AGM,SLA in several aspects.They work longer(lifetime, cycle-life), our 10 years experience shown avarage lifespan of 5000 cycles (depending on the discharge rates, minimum 2000, maximum observed 8000).More poweful, with available continious discharge rate at 3C (3 times its capacity), LiFeYPO4 provide more energy than AGM,SLA.No acids, unlike AGM,SLA the LiFePO4 does not contain life threathening substances.Non explosive, Li-Pol (Polymer) and other batteries frequently used in consumer electronic (Phones, Tablets) are extremely dangerous when physically damaged or misused. You can actually pierce LiFePO4 with metal and not cause fire or explosion. Shortcut it for long periods with the same (little to none) effect.Our Serivceswinston Batteryis high power lithium iron phosphate(LiFePO4) batteries.We are the official partner of Thunder Sky Winston lithium battery cells for sales and technical support.Warranty is 24 MonthWith over eight years friendly cooperation,we had many safety delivery method for options ,All the fresh cells direct from factory with best servicesLi-ion batteries are classified as Dangerous Goods for transport according to the UN Model regulation for the Transport of Dangerous Goods.They are classified under CLASS 9 Dangerous Goods due to their dual hazard properties associated with their chemical and electrical contentUN 3480 : Lithium-Ion BatteriesWe ship lithium ion battery by a 20 feet Dangerous Goods container by sea from Shenzhen to USA every month.For more information of Thunder Sky Winston LiFePO4 Battery Cells. pls feel free to contact DeligreenFactory Overview
