Nothing wrong with bullet connectors.Actually its more efficient than deans or any other connector as far as electrics are concerned(much lower resistance). You just have to make sure you plug the polarity in right with bullets! Would be a better setup IMHO. I run 6s boats in parallel and the bullets are the only way to go with boats.Ive seen too many de-soldered connectors in the boat scene. However, the boats pull massive amps!! These motors we use in 1/8th buggy-truggy setups are very similar as far as motor size in boats of 32inch in length.
