OEM rechargeable lithium battery pack 11.1V with high quality for electric power system
1. Li ion battery pack cell was in High safety since we use the samsung cells
2. Low internal resistance for Li ion cell, Low self-discharge rate for this Low Temperature Lithium Battery
3. It has More than 500 times cycle life (long life)
4. this Lithium battery has small self-discharge, room temerature for a fully charged Li-ion storage kept in a self-discharge rate about 10%
We can make customed all kinds of lithium ion or li-polymer batteries by the requirements from customer as we have a strong R&D team.
11.1V 5Ah rechargeable li ion battery pack with with low temperature cells for power tools
