i just noticed... are those two batteries? im guessing in parallel? is that just to have more run time? and also just to use up some space left over?
OR, is that running at 24V? many motors can take quite a bit of current abuse without burning... of my whole robotics career..(short, but..) ive only burned two drill motors... and that was during my first OCCRA season. and wheelchair motors, which were supposed to be run at 12V, were fine running at 24V.. for an entire battery charge cycle..well of course they got quite hot, but still they are fine. and ever played with those small motors rated 3V? the ones that come in the small handheld batterypowered fans... well, those, you can run them at 9V for quite a while. i dont think there's more rpm with the 9V than with a 7.2V though. didnt have a way to test it, so just a thought. perhaps sumthing to do with heat and efficiency... soooo, if you run the chips at 24V, how long will they last? anyone tried this before? i dont have any to spare so cant test it myself... id like to know how long itll last with some resistance. not a freespin...
