High Capacity Lithium ion Battery 18650 and 26650 and 21700 Battery
To provide a larger size and higher capacity cylindrical lithium-ion batteries, we have made the best 18650, 26650 and 21700 batteries.
The size of a 26650 battery and 21700 battery is a larger diameter and longer length, because of their size, they are able to deliver much power to a small flashlight.
Moreover, the nominal voltage of the 26650 lithium-ion protection battery is 3.6 volts, and the maximum capacity can be 5200 mA/h (5.2 A/h), which is very suitable for high-consumption devices that require sudden peak currents.
At the same time, we can asseble this battery in Series and Paralles to meet your different needs. And the protection circuit can be built-in for safety control include over-charging, over-discharge, short-circuit, and temperature control.
The additional connector made by JST, Molex & Hirose is also available with a custom length of wires. https://www.li-polymer-battery.com/li-polymer-battery-connectors/
