3. Our battery cells catalog
CTS uses Lithium Iron Phosphate (LiFeP) batteries for electric vehicle conversions. The battery cells utilize the latest advancements in nanotechnology.
All of our battery packs(12v-400v,12ah-200ah) are made of those following lithium ion pouch cells. These cells are very safe in normal operation, DO NOT cause fires as the early Lithium Phospate batteries.
The selected batteries solve the Safety concerns of being in an Electric Vehicle (EV) / Electric Car Conversion Kit, every cell has a built-in safety device if punctured or damaged, will vent to the atmosphere making the cell much safer.
Compared to lead acid battery, it is 4 time lighter in weight , and 4 time longer in lifespan.
Compared to li ion battery, it is 2 time lighter in weight , and 2 time longer in lifespan.
Compared to lithium ion square battery, it is 0.5 time lighter in weight , but much safer when using.
