Description

This kind of battery pack could be used on electric vehicles, ultra-light airplanes and other vehicles and devices. It could be used to discharge at 4C***0A continuous and 6C***0A max. the battery case has special function of water-proof, shock-proof and heat preservation. Solution Use our company�s high-rate steel case LiFePO4 cell 3.2V/*0Ah (*8/*2/**8S-Fe); be connected in 5P*4S to build the pack *2V/*0Ah. The total output is *6.8V/*0Ah, 3.*4KWh. Overall dimension of the single cell: T: *8.5*W: *2.5 * H: **8mm Weight of single cell: �0.5KG ***** parameter of the battery pack: 1). working voltage: *6.8V 2). Nominal capacity: *0Ah 3). Output power: 3.*4KWH 4). maximum output voltage: *2V 5). Minimum output voltage: *2V 6). Charging restrict voltage: *6V 7). Continuous discharging current: **0A 8). Instantaneous discharging current: **0A, *0S 9). Maximum charging current: **0A *0). Instantaneous charging current: **0A, *0S *1). Total weight of the battery pack (not including the case): *0KG 3. dimension(for reference): The dimension of the battery case can be designed according to the customers� real space for putting the battery. 4. BMS: Be built up by one general control module and two sub-control modules. General control module Sub-control module (Built in the battery case, not including the aluminium alloy casing) 1).
