LiPo battery peak current burst C rating

[EnEE]

Hi,
as I know the burst C rating usually refers to the max current allowed for 10 seconds.

if I need higher current for 1 second, I can do it?
The heat is the problem here?

Um, why do you ask? Whatcha' makin'?

because lipo battery sometimes explodes...
motors require high current for the first seconds, so I want to know what's cause the battery to explode (and why drones usually use lipo)

Try this a basic start

It is aimed at hobbyists, but based on what you asked you really should consider reading it. It explcitly explains explosion/fire causes.

I read this article. This is a good example for my question. If the truck need steady current of 65A and 100A for the first 3-4 seconds,
I know that for the first second it draw about 150A.
Can I use battery with Max burst current of 100A?
