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 |

You may need to ensure air can flow into your hull. If this is OK, let us know. Roger -------------------- |

Roger 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 |
