I just finished my first build (first dabble in any such project really) and it’s almost great - i’ve just been encountering a few glitches and such that need ironing out.
the big one right now is, i think, vesc related - i’ll include the info i think might be relevant at the end here. i haven’t got much data to work off (only done a couple of rides), but so far: i’ve started my ride off fine. board is working perfectly. then for whatever reason i have to do a big brake (long hill for example).
after a few seconds of braking they fully cut out and nothing responds for couple of seconds. then i get some weird shit occurring. there will be latency both for acceleration, braking and even releasing the throttle (about half a second of latency for all actions). brakes will start and then after a couple of seconds cut out, even light braking. unloaded the board will respond fine, instantaneously. this only happens when i’m actually still on the board.
12s 38120 Headway cells Vanda VESC with Ackmaniacs BLDC tool Turnigy SK3, 192kv, 6374 motor VESC SETTINGS: Motor min: -30A Motor max: 70A Battery max: 50A (i hope this is safe, cos i see conflicting information and very little of it for the 4.12 vanda vesc, but that’s what their website says is fine for continuous) Battery min (regen): -30A (i had this at -20 and thought maybe the vesc can’t handle the difference when braking hard, but it occurs the exact same on both settings) I’m currently on Current mode (brakes and reverse set up and working fine), but it also occurred with current mode brakes no reverse.
anyone have any thoughts on what the issue is?
