i've got a RC boat that runs 3 motors through 1 esc (25amp)
now it was running 16cells but ran out of puff after about 5mins
so i tried a 12v 7amp gel battery
much better
but now the esc keeps over heating?
any ideas
thanks

Do you have your ESC where it can get no air flow over it? You may need to ensure air can flow into your hull. If this is OK, let us know.

no its quite a big boat (graupner giant racer) and its got lots of room and air going in and out
i've put a 50amp water cooled on and its going really well but i don't think it should need an esc so big
