Yes thats right don't rely on youtube but it's gives examples of what happens when it goes wrong.
I don't know why trakpower are saying a pack will not swell did you speak to the receptionist or something.
A pack will swell if put under to much load experienced it myself. I do agree with you about the smoke and fire virtually nil chance.
Some lithium battery's have protection circuits built into them to prevent To much current being drawn/overcharge/over discharge.
The Lipo's we are using have no such circuit in them.
The best example of pulling to much current from a lipo is to create a dead short which is the most extreme example of pulling to much current. I can almost guarantee that any lipo will either puff or melt the solder from the top of the cells and then it is ready for the bin.
I know the example was a system pulling 100A with the battery rated at a constant current of 87.5 which the system would probably run for a while but the battery life will be reduced. It may not puff but the battery is being used outside of it's safe rating so there is the possibility of damage.
The information you are getting is incorrect.
I don't know what question you put to trakpower. Try asking them if you took one of there battery's and pull more current than it's rated at what would happen. I think the advice you would get back would be not to do it.
If it was done once then the battery would likely suffer nil effects as long as it wasn't massively stressed but if it was put into a system that was pulling above it's specification constantly or on a regular basis then you will likely damage the battery.
