DRo Posted January 12, 2022 Share Posted January 12, 2022 Hi I've just picked up a 2nd hand car, with a Hobbywing 880 dual brushed esc. (and brushed motor). I don't have a programming card for it yet (I've just ordered one) so at the moment have no way of telling whether it is currently set to lipo or nimh mode. Am I going to damage anything if I run it with the wrong type of battery for a few days until the card arrives, and if not, is one way around less risky than the other? ie. lipo battery in nimh mode, or nimh battery in lipo mode? If I just get a loss of performance or something then that's fine as it's only short term - I just don't want to damage the esc or kill a battery. Thanks!

walkbythesea Posted January 12, 2022 Share Posted January 12, 2022 You can destroy a lipo battery in nimh mode because a lipo needs the safety of a low voltage cutoff, a nimh will safely discharge to a lower voltage than a lipo and still recover. You can use a low voltage lipo alarm instead on any ESC without an LVC, they just plug into the balance cable and beep like hell when the voltage is getting down to your preset alarm point.

walkbythesea Posted January 12, 2022 Share Posted January 12, 2022 Running in lipo mode with a nimh won’t do any harm but you won’t get full runtime as nimh will usually operate for a while even below the usual lipo voltage cutoff point. 1 Quote Link to comment Share on other sites More sharing options...
DRo Posted January 12, 2022 Author Share Posted January 12, 2022 Great thanks! I have some lipo alarms so might try that route. Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted January 12, 2022 Share Posted January 12, 2022 Can you not program it without the card? Usually means consulting the manual and counting LED flashes.... Quote Link to comment Share on other sites More sharing options...
DRo Posted January 12, 2022 Author Share Posted January 12, 2022 No there doesn't seem to be any way to do it. I've seen videos of people doing that but they seem to always have a button to hold down to get into that mode, but I don't seem to have anything like that. Never mind, hopefully the card will arrive in a few days, until then I'll just keep a close eye on my cell voltages and not run it too hard. Thanks.
