Shenzhen Blumoti Energy Co., Ltd. is a leading Chinese manufacturer and supplier of 18650 battery 3.7v 3000mah. If you are looking to source durable, bulk 18650 battery 3.7v 3000mah from China, feel free to contact our factory for details. Custom orders are welcome.
18650 is one of the cylindrical cell formats and is a liquid lithium-ion battery. A 3000mAh 18650 cell falls within the high-capacity range, with the maximum capacity for 18650 cells being 3500mAh.
3000mAh cells are available in both high-capacity and high-drain versions. The high-capacity version is designed for low-current discharge and longer runtime, while the high-drain version supports a maximum discharge rate of 5C, or 15A, making it suitable for power tools. It offers a good balance between runtime and power output.

Applications for 3000mah 18650 battery
3000mAh 18650 batteries are mainly available in two types: high-capacity cells(1-3C) and 5C high-drain cells.
These cells feature high capacity and long runtime, making them ideal for low-current devices that require extended operating time.
Common applications include power banks, standard flashlights, camping lanterns, laptop battery packs, small fans, Bluetooth speakers, radios, small energy storage systems, and backup power supplies.
3000mAh equals 3Ah, so a 5C discharge rate supports approximately 15A discharge current.
These cells offer strong discharge capability and are suitable for high-current, high-power devices.
Common applications include power tools, electric bicycles, electric scooters, drones, RC aircraft, RC cars, cordless vacuum cleaners, air pumps, high-output flashlights, and searchlights.
Customize the capacity, voltage, discharge rate, BMS, connectors, and more to fit your needs.
Sample service available; bulk orders supported.
Reliable after-sales follow-up, and a one-year warranty.
OEM/ODM services available.
Yes. All of our cells are true-capacity cells with no inflated ratings, and they are CCC certified.
It depends on the current requirements of the device. Higher-power chainsaws and floor scrubbers generally require 10C high-drain cells. We offer a suitable model on our website: 2500mAh, with continuous 10C discharge, equal to 25A.
