Ebay doesn't have the 18650 VT Konion 1100 cells at the moment. These are not to be confused with regular 18650 cells. I have a quantity of regular ones (2200mah).
Regular 18650 cells have a max. discharge rate of 5 amps and that's about all they will tolerate. I have put that to the test before.
These are something new that have a discharge rate of 25 amps per cell. I can see some advantages in a setup that doesn't exceed this since they do charge up to 4.2 volts per cell. They are also said to hold a pretty good voltage level under a load.
The A123 cells are great, but their voltage level sags when you load them.
Just something new here that I would really like to play with too.
I have a feeling they are in some type of tool battery pack.
