Amberwolf: I am using Opus BT-C3400 to discharge them at 1A and for more discharging power I use iCharger 206B, so current and capacity measures comes from these chargers.
Hillhater: Assuming my inside temperature is 25C and your chart data, by the end of the discharge cycle I would get 55C which is very hot to touch, 60C is about where your fingers start to burn and you cant keep them on. So data seems to be in line with what I am getting. Discharging at 3A they do get hot, but never to the point where I cant keep my fingers on, feels hot but not burning.
I have some good Samsung 18650-26C that I have also tested and temperatures do feel the same. So maybe Tesla chemistry is not for high discharge rates, but is kind of slower discharge rate cells with good cooling system?
The whole reason I bought Tesla module was to eliminate heat, but it turns out they heat up as well. I am using Samsung cells for my pack and discharge them at 3A per cell, which is about 1.2C, pack is usually warm but never uncomfortable to touch and I'm in Florida so It's 28 - 30C outside. I'm starting to think that I worry too much about them being warm or slightly hot. It's just the way it should be.
