I recently replaced one of the VESC’s (hobby king 4.12) as I blew one up, completely my fault. After this it has developed an issue where when accelerating the motors cut out, usually happens after a couple seconds of acceleration which is accompanied by flashing red lights on the VESC. I can get it to do the same thing when unloaded lying on its back but only if I floor it from a standstill.
The settings are exactly the same as I was using before, 45amp max 50amp absolute max with voltage cutoff starting at 36v and ending at 33v on a 10s lipo pack (2x turnigy graphine 5s lipos), VESC’s are not connected rather the receiver is split into both. The issues also seems to be more pronounced when the board is fully charged.
After reading some advice on here I tried straightening the receiver cable and moving it away from the VESC’s but didn’t make a difference. I ruled out that: it was a temperature issue as it starts happening immediately and doesn’t get worse with time, that it was an over amperage issue as its a dual motor config and happens on flat though is slightly worse on hills, that it’s a voltage sag issue as it seems to get better as the battery discharges not worse.
Any ideas much appreciated as I’m completely lost at this point, thanks
