Product Description

This 26650 battery is the larger version of the well known 18650 battery.

This version packs much more energy storage than the standard 18650. But the 26650 battery is larger in diameter and length than the 18650.

These are, just like the 18650, 3.7V DC output per battery.

They will NOT fit into 18650 battery holders and require their own size holder.

But its the perfect way to give your project the power it needs.

You can still use 18650 chargers to charge these. So any 18650 charger that they will fit in, it will charge in.


This is a great example of a charger that you can integrate into your project and charge single cells with:

18650 Lithium Ion Battery Charger w/MICRO-USB Power Input


MARKED BATTERY CAPACITY NOTICE: These are NOT nice Samsung/SDI, Japanese cells. They are made in China. They almost always lie about the rated capacity on the battery. The label they stick on should NEVER be trusted. As a general rule, no matter what the text on the side of the battery claims, they are usually around 2800 mAh per battery or LESS! Maybe a little more, maybe less, we have no way of testing. But for the price, they are pretty useful battery cells. If you are working on a budget and need power for your project, you can't really do better than the these cells. If you want higher quality batteries, with genuine ratings printed on them, you can contact us and we can get some genuine Samsung or Japanese 26650's for you. But they will be MUCH, much more expensive per single cell.


SAFETY NOTICE FOR ALL Lithium Batteries:

For either Li-ion or Li-po batteries. You should ALWAYS charge safely. Never charge at a higher rate than you are supposed to. Never discharge at a higher rate than you are supposed to. Never leave un-attended when charging or discharging. Never puncture or crush the batteries. Never over charge or over-volt the batteries. When you buy a lithium style battery from Vetco, it is assumed that you know what you are doing. Vetco can neither educate you or accept any liability for the use or improper use of any style of lithium battery.
