Selling a new Lithium-iron phosphate battery (LiFEPO4). The batteries are assembled and sorted on high-precision factory equipment with a minimum error in both capacity and internal resistance. This ensures a long service life without imbalance between cells. Capacity 20Ah voltage 48v. The battery comes with the BMS board ready-made. Lithium iron phosphate batteries are more frost-resistant, have a greater number of charge-discharge cycles, support faster charging, and have a more stable voltage compared to conventional lithium-ion and lithium-polymer batteries. High current output, the ability to quickly charge (up to 2 hours) are the big advantages of this type of lithium battery. Cells themselves in a rigid aluminum case. Additional housing not included. Nominal voltage 48V maximum voltage (charge): 58.4V minimum voltage: 38.4V Maximum discharge current: 120A Rated discharge current: 30A Maximum charge current: 10A Nominal charge current: 4A Service life 2200 cycles (before losing% 20 capacity) or 10-15 years Dimensions: 216 * 140 * 135mm (or your sizes to order) weight: 6.2kg There is a possibility of individual production, according to your parameters (dimensions, capacity and voltage) It is possible to manufacture batteries for electric vehicles, for solar stations, wind generators and .td 3 year warranty !!
