Hi this was my first build and I am writing to find out why my VESC died only after 3 rides?
I built my 1st skateboard after months or doing my homework and putting off building everything I had purchased.
- I built my own 12S6P battery pack using Samsung 25R cells.
- I used two sensorless motors (Turnigy Aerodrive SK3 - 6374-192KV)
- My VESC was Flipsky Dual FSESC4.20 100A
After building my board and configuring using the VESC Tool, the first problem I noticed was stalling. The motors would both spin fine with no load, but once I got onto my board, the motors would both shake then stall and trip the VESC.
I discovered my cut-off voltage was too low and also the current setting going to the motors. Once I adjusted the setting things got better, but still the VESC would fault and I still experienced stalling, what I’ve come to know as cogging.
I am not sure what is at fault? The Flipsky VESC or the dual sensorless motors.
I wrote to Flipsky several times, but this girl Helen would only reply to the email and never put me in touch with one of their engineers. I was told by Flipsky that my sensorless motors were not the problem so I provided them with my setting but they never told me what was wrong.
When I wrote Flipsky that my VESC popped and died they replied that they would give me a 10% discount code, not replace their VESC.
I have wrote back to Flipsky asking to speak to their engineer to explain to me what exactly cause their VESC to die and I provided them the VESC settings, they stop responding. It is the weekend, but I don’t expect Flipsky to stand behind their product or give me a straight answer, nor replace the VESC.
I posted on this forum to get help and learn a few things since Flipsky never provided help: Not enough power to move me
Long story short my VESC popped after 3 rides, following the advice I got. At the time I was at home trying to start and stop the board with me on it and tweeking my VESC settings. This is the last known setting I had before my VESC died:
I now have to buy a new dual VESC and I don’t know what to do?
Should I replace my motors also to have a hall sensor? was this the reason my VESC died and kept stalling. Flipsky told me my motors were fine.
Should I buy another Flipsky VESC? are they reliable? I searched this forum and some say they are not good with false specs or inferior components.
Someone who made a youtube video told me Flipsky does not make their own products and just re-brands them and I could buy the same for 1/3 the cost off a Chinese site.
I don’t know what to believe and afraid to see my money go up in smoke again. So I am asking someone with years of experience or having made multiple boards to help me decide what to buy or upgrade.
I love this sport and I am super bummed out this happen to me.
