Product Details

Custom li- ion 25.6V 60Ah intelligent Lithium ion Rechargeable Battery Pack for Electric Vehicle

1.Excellent high and low temperature discharge performance .

2.Widely using temperature range, lower temperature lithium battery can be operated in -50°C~+60°C(specialized battery).

3.Excellent storage life and reliability. With low self-discharge, selft-discharge rate≤5% monthly.

4.Various combination,also can make special design for customers

5 The battery pack is safe and high temperature resistant. The cycle life is long.

6 The battery pack has a high cycle life, which conforms to the values of low carbon, energy saving and environmental protection.

7.The battery has a built-in BMS system with multiple protection functions. The protection system (PCM/BMS) is all equipped with the most advanced chips in Japan and the United States.

8 Core materials include LiMn2O4 (lithium manganate), li-ni-co-mn-o (ternary material) and LiFePO4 (lithium iron).

We can customize all kinds of lithium ion or li-polymer batteries by the requirements from customer as we have a independent R&D team and OEM/ODM is acceptable .
