LiFePO4 battery pack 72V/50Ah

 

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-200A continuous and 6C-300A max. the battery case has special function of water-proof, shock-proof and heat preservation.

 

 

 Solution A

1.       solution:

Use our companys soft package LiFePO4 cell 3.2V/50Ah (13/240/240-Fe); be connected in 24S to build the pack 72V/50Ah. The total output is 76.8V/50Ah, 3.84KWh.

Overall dimension of the single cell: T: 13 *W: 240 * H: 240mm

Weight of single cell: ≤1.6KG

Solution B

1.       solution:

Use our companys high-rate steel case LiFePO4 cell 3.2V/10Ah (28/82/118S-Fe); be connected in 5P24S to build the pack 72V/50Ah. The total output is 76.8V/50Ah, 3.84KWh.

Overall dimension of the single cell: T: 28.5*W: 82.5 * H: 118mm

Weight of single cell: ≤0.5KG
