My boards been out of action for the last couple weeks while I was waiting on some extra batteries to arrive and get my repaired VESC back from @chaka. I’ve had the board back together for a day now and for the most part it’s been running perfectly.
However when I went to ride up a fairly long and steep hill tonight I got about half way up and I slowly began to lose power until it got to the point where the board was barely moving. I got off for a couple seconds then got back on and started riding again and it seemed to have full power back but about another 10 - 20m up the hill and the same thing started happening. This basically happened another 3 or 4 times till I got to the top of the hill.
I’ve ridden up this hill many times in the past without any issues and the battery was still at 65% at the top of the hill so it shouldn’t have anything to do with low voltage cutoff kicking in. Since the board was running last (when I didn’t have any issues with this hill) I’ve upgraded the battery from a 10s3p to 10s4p pack, replaced my enertion remote with a GT2B and had my VESC repaired. While @chaka had my VESC he flashed it with 2.18 firmware (from the original 2.16) and it’s now running in BLDC mode (was running in FOC before the repair). Other than that, I’m using the same firmware settings as before.
