protection board:

 

Compared with SLA battery,lifepo4 battery has many advantages:

1Long cycle life:up to 2000 times

1. Green: Non-Toxic, comfort to RoHS.

2. Long cycle life: > 2000 cycles, while Sealed Lead Acid batteries only 750 cycles and NiMh batteries only 500 cycles)

3. Safety

The safest battery in the world till now, which does not burn with 30V charge voltage and it does not explore when you puncture the battery. UL and CE approved.

4. Light weight and smaller dimension

The dimension is smallest and the weight is lightest when compare with other battery. 1/3 weight of SLA, 65% weight of NIMH.

5. Great capacity and more powerful, rechargeable battery

High discharge current, 1C continuous, 3C pulse for normal cells and 20 C for special design

We can install many single cells in series and in parallel and it can fully discharge

6. Good thermal stability: - 40°C to 70°C

7. Back fast charge, good consistence, no memory effect, can equip battery charger.

Can be recharged anytime, no reduction of the capacity

7. Widely application, customize solutions, mass production, OEM/ODM/buyer label provided, factory passed TS 16949, ISO 9001:2008.
