Compact Size 12 Volt LFP Battery Pack, 40Ah Lithium Battery In Light Weight
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:
