Few more things, keep battery leads as short as possible. Motor leads can be extended in a pinch in preference. (ESC's don't like long battery leads.) Wire gauge needs to be sufficient to carry the expected current for the expected distance. Make sure ESC and batts get good airflow for cooling. |

Little bit more soldering and also dug the servos out. The tester still works fine even after the short and butchering it. I really hope it cools down a bit tomorrow because the last few days have been hell, and I haven't really felt up to doing any serious work in the heat. Airflow for the ESC I had considered but I was thinking about putting the batteries in a wooden box. Didn't really think too much about them heating up... Maybe i'll make a wooden box with holes in it! |

So when the batteries finally shut off could it not switch to another bank of batteries? And couldn't a arduino handle all that and more? |
| vtsteam:
Tom it could be handled with a battery switch, or even simpler still, if cells were the same type and capacity, paralleling them for longer duration. Simon, I get the same way when it's too hot. Small workshop jobs start to seem too complicated to attempt. |

Well it took two seconds for the tyre on the little contact roller to stretch and split. I think I might have to glue the next one down, but even then it'll probably have a short life. But hey it seems to work. The motor turned, but i'd forgotten to insulate the three connectors between the motor and the speed controller and got a bit of arcing there. It was after that that I noticed the tyre was wrecked. I'm not sure if glue would even work though. Might have to machine thicker rubber rollers or something. |
