TC3755 3.7v 5.5ah li ion polymer battery

3.7v 5.5ah li ion polymer battery

3.7v 5.5ah li ion polymer battery does not contain lead, cadmium and other toxic heavy metals, the material is relatively safe, which is convenient to provide you with batteries required for various equipment. Tycorun, the best lithium ion battery manufacturer, accepts customized battery specifications, so you don’t have to worry about finding a suitable li ion polymer battery. Li ion polymer battery is still far ahead in technology. The electric heating peak of 3.7v 5.5ah li ion polymer battery can reach 350℃-500℃, while lithium manganate batteries and lithium cobalt oxide batteries are only around 200℃, and the working temperature is wider. High-capacity, non-polluting li ion polymer battery is advocated by the government and enterprises.
