24V 40AH LiFePO4 Lithium Battery Module For Electric Vehicle
Quick Detail:
1. Soft-pack LiFePO4 cells inside
2. Compact in size and light in weight
3. BMS manages to each cell for high reliability
4. Extra long cycle life - 5 times life of Lead Acid and 2 times of NiMH
5. Extremely safe: No explosion, no fire under collision, over charged or short circuit
Description:
Compared with the same capacity lead-acid battery, LiFePO4 battery is 1/3 smaller in size, 2/3 lighter in weight, 5 times longer in cycle life, more economic and eco-friendly.
LiFePO4 battery replacing Lead acid battery is an inevitable trend.
Compared with same capacity Li-NixCoyMnz battery, LiFePO4 battery is 2.5 times longer in cycle life, also most the same in weight & size.
Basic knowledge:
Lithium ion battery, classified by the anode material, can be divided into li-MH,Li-Co2, Li-NixCoyMnz, and Li-FePO4, etc.
Classified by the battery shell, can be divided into plastic shell, stell/iron shell and aluminum shell.
All these lithium ion batteries have their own advantages. The technical data of their comparative performances is as follows:
