43.2V 40Ah 21700 Drone Battery Packs
CMB proudly designs and manufactures battery packs specially crafted and equipped for electric surfboards and eFoils. Learn more about our electric surfboard battery offerings below, and reach out to a CMB team member today to get started with your custom battery pack design.
The engineering team of CMB is devoted to designing drone batteries with long-lasting and reliable quality. With a high discharge current and weight limit of 21700 battery pack for drone, we’ll accurately calculate the internal resistance and temperature from the 43.2V 12Ah 21700 battery pack. We’ll consider the 21700 li-ion cells, nickel materials, wiring routes, and BMS solutions to reduce the internal resistance and temperature, which make the 12S 21700 drone batteries with optimal performance and long cycles.
