Have made some reasonably hi current discharge test, around 60A.
1)I can push those old Konions 4P to deliver 60A for max. 20 seconds before they fall under 3V/cell.
2)No temp raise over ambient on the tabs. Only significant temperature raise is during 1min after every discharge test, cells start heating up from the center of the can and after several consecutive discharge kicks, totaling 1.25Ah (edited)
(~1min.15 sec), max temperature registered was 46C at center of the cans.
3)Have 2 digital thermometer, but also only 2 hands, no way to measure temperature in 2 points and take pictures a same time
Now some pictures.
The transparent poly prop tape is a place holder for kapton tape. It will react to any thermal event in this testing setup to reveal hot spots.
Did the load, but plastic terminals start to melt instantly and I was at risk getting sun burn.
My first idea was to make acrylic boxes around packs, but heat shrink will increase temp exchange eliminating static air over the cells.
