I like to put a piece of red electrical tape around the + socket on my batteries just as a sanity check.
You really are not eliminating the intermediate connector, instead you are locating the connector in a pair of holes on the battery. It is possible to use cheap/bad/worn out bullets have major issues with resistance and heating things up.
Watched a guy the other day melt the plastic on two batteries around the inboard 4mm posts. He had a loose fit and it would heat up as the connector would arc.
