Lithium Ion Cylindrical Battery 3.7V - 18650 Cell (2600mAh)

This lithium ion battery contains a 2600mAh and a protection circuit that provides over-voltage, under-voltage and over-current protection. Yet, it is slim and easy to fit into many project cases.

This cell can provide 2C of peak current (4400mA). Note that these batteries are not designed to sustain such high loads, we suggest keeping any constant current draw under about 0.5C (1 Amp)

The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 2.5V. However, even with this protection it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 0.5C (1 Amp) or less.
