First of all, 99% of the graphs below are from HKJ. These were done by him, I am simply placing them in this thread for easy reference.
All of the below batteries are ones bigger than 18650.
26650
These are the same diameter (approximately) as a C sized battery, and the same length as a 18650. For this reason they are often used in C maglite mods, along with in lights that want a longer runtime than a 18650.
This battery can supply extremely high currents but at the cost of capacity, it is rated for a 70 amp continuous discharge.

Keeppower 26650 4000 mah LiCo Protected
This battery can handle currents up to 7 amps, but there is variation in the batteries.

Trustfire 26650 5000 mah LiCo Protected
This battery is one of the few good fire brand batteries. It does well up to the 5 amp load, and it would be a good idea to keep the load under that level. There is a small variation in batteries.

This is one of the few batteries where the true capacity exceeds the marked capacity. It does well up until 10 amps, all while having over a 4000 mah capacity.

This cell also exceeds it's rated capacity, but is not as good as the ICR26650. It can handle loads up to 7 amps.

32600
This is the exact dimension of a D cell so is a higher voltage replacement for D cells.
Ultrafire BRC32600 4000 mah LiFePo4
This cell has a lower capacity then stated, but can handle loads up to 20 amps. Due to being a LiFePo4, it does this at a low voltage.

This battery has not been tested yet. One can guess that it can handle loads fairly well due to the large size, but we can't know for sure.
32650
These are slightly longer than a D cell, and higher voltage.
This battery has not had discharge curves done, but the capacity has been tested. It handled currents up to 13 amps.

There are no discharge curves, but at a 3 amp discharge it tested at 4697 mah to 3 volts. At a 1 amp discharge it tested at 5191 mah. This is fairly impressive.

26500
26500 batteries are the exact size of a C battery, but they are have a higher voltage.
This battery has not had any tests done on it, but if the specs are true is a very good battery.
