I agree with Livinloud, a larger selection of high quality batteries would be nice.
Besides the previously mentioned panasonics, maybe some brands such as King Kong, AW, Sanyo, KeepPower, Efest etc.; basically anything that isn't an "_____fire" brand.
Here is a link to one of them:
King Kong 26650 4000 mAh - ICR26650 Button Top Battery

I agree in principle, but would say stick to the core manufacturers of cells themselves like Panasonic, Sanyo, Samsung, Sony, and don't worry about rebranders like efest, keeppower, etc.

Maybe a dumb Q, but why bother with these, when you can have 3400 mAh 18650s ?

Seems like a 26650 ought to do a whole lot better than 4,000 mAh on account of having over 2x the volume of an 18650.

Another vote for the Mitsubishi 1.8W 638nm diode :)

They do...

5200mah 26650 battery

However, King Kong 4000mah 26650's have much lower voltage sag under high loads
compared to NCRB18650's or the higher capacity 5200 mah 26650's.

That's the main attraction. Sometimes people care much less about runtime and more about maximum performance.

I would like to see a supplier of these batteries besides fleabay. They work great in single cell high output builds. I dissected one and they don't appear to be re-branded cells and they test to whats stated on them.
Shenzhen IMREN Technology Co.,Ltd.,Battery£¬Battery Charger£¬USB Cable£¬Li-On Battery

Of course I don't need any right at the present. I have about twenty of them. But when I run out it would be nice. :)
