Lithium titanate battery

1)Quick Details

LTO 48V20Ah E-Bike Battery

2)Features

We adopted LTO 18650-1500 steel shell and 18650-1300 pin battery.
The lithium titanate battery has the ability to charge and discharge at minus 50℃ to above 60℃, which means that no matter in the north or south, in winter or in summer, the vehicle will not be affected by the battery "shock" and work.
Lithium titanate battery can be charged and discharged quickly, which not only greatly reduces the charging time, but also has little effect on the cycle life and strong thermal stability. There is no need to replace the battery frequently, the cost of operation and maintenance is lower.

3)Application

This is a project about E- bikes.Supply to the northwest of China, where the weather is very cold and the temperature is very low.LFP can’t satisfy the condition.
