Lithium Polymer Battery Cell Selection

There are many different types of lithium polymer batteries in the market. No one type works for all applications. For example, robotics need a high discharging output; power tools need high discharge C rate; energy storage systems need high power density; starter batteries need to be operable in freezing temperatures; and batteries with daily charging/discharging usage that need a long cycle life.

We have been in the lithium polymer battery application industry for numerous years. We are familiar with the battery supplier chain and emphasize on quality. We will offer you the most suitable lithium polymer battery cells based on performance, price and reliability.

Smart Battery Management System (BMS)

Our unique battery management system separates us from other competitors. Most of our competitors have to rely on 3rd parties to complete their battery management system design.

Using lithium polymer batteries safely and smartly has become a top concern today. Our Smart BMS offers safety features like temperature protections that will not allow unexpected battery abuse by charging in high temperatures or discharging in low temperatures. These extreme conditions are the main cause of hover-board battery fires in late 2015.
