3.2V 40Ah Rechargeable LiFePO4 Lithium Battery Module / Pack

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.

How to use:

Connect several such module batteries in series to reach the voltage you want. For example, if you want a 36V 30Ah battery pack, just cascade 12 pcs 3.2V 30ah module batteries is OK.

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:
