The Doublepow ICR18500 is a rechargeable lithium-ion battery designed for flashlights, power tools, RC toys, and EDC devices, featuring a nominal voltage of 3.7V and a capacity of 1500mAh. Built with ICR cells, it delivers high-current output with low internal resistance, supports fast charging, and provides stable high-current output for loads—economical, durable, and suitable for a wide range of medium-power devices.
This product is available in two configurations to suit different device connection needs. The Button Top features a protruding terminal, fitting spring-loaded devices for more reliable contact. The Flat Top has a standard flat terminal, suitable for spot-welding assembly or compact battery compartments. Both versions use the standard 18×50mm size and weigh about 39g.
