This 7.4V high power battery pack was design by YFJ company which has max discharge current at 7.8Ah. our company has focused more on quality for High Power Battery Pack as :
1.Lithium batteries are light in weight, small in size, large in capacitance, high in energy and high in safety
2.12V Lithium Ion Battery core raw materials. The core itself has overcharge, overpressure, and overlet the flow of four safety protection. It fundamentally solves the hidden dangers of short circuit, leakage, explosion and other aspects of Lithium Cell Battery.
