Sorry to say that since Lipo Battery cannot be shipped through DHL/FedEx/EMS, so this product is discontinued now.
This high discharge LiPo is a great way to power any R/C, robotic, or portable project. This is an excellent choice for anything that requires a small battery with a lot of punch. The voltage is low enough not to tax your regulating circuits, and the discharge rate is high enough to accommodate a lot of electronics and motors.
We customized it by using an Arduino Compatible Power Jack to make easier to be integrated into any Arduino Project. It is also the best selection for Arduino power robots.
The battery has two cells and outputs 7.4V storing 2500mAh of charge.
