MTSVESC6.0 200A VESC6.0 Based Controller 12S Lipo

After having many failures with the original 4.12 60A VESC due to FOC caused DRV errors (I'm sure many can relate), I stumbled across this controller about 2 years ago. The price was hefty in comparison, but the performance it promised was unparalleled. Unfortunately, the claimed 200 amp of continuous current is very optimistic. I purchased a bluetooth module which allows me to connect the VESC to my phone, program, and monitor it. I found that its' readings are extremely accurate. I built an electric bike with a mid-drive motor setup, 50v Lipo graphene packs, and this controller. I did some testing with the setup, and found that on a day with about 70*F ambient temps, I could only pull about 100-120 amps continuous. Granted, this is much better than the previous controllers I have used, but it is not anywhere near the claimed 200 amps. When I tried to put this much current through the controller (full 200A), the motor would simply stall. I believe it is a limitation of the motor simply being overloaded and not the controllers' doing, but I thought I would mention it. I could only realistically output 180 amps; enough to get me to 30mph from a standstill in under 3 seconds! Bonkers fast for a deathtrap Ebike. But after about 10-15 seconds at this current, the temperature cutoff would quickly reduce my current to below 100 amps, and oscillate a few times before coming to a rest at 110 amps or so. I decided to take it upon myself to fix this overheating issue by removing the stock thermal pad which was on the backside of the MOSFETs, and thermal glued 6 individual copper pads (as if I did one slab, it would risk shorting the MOSFET's N-channels!). After this, I installed a new thermal pad, and also put huge heatsinks on the backside of the controller. These two mods allowed me to now pull upwards of 160 amps continuously; about 7-8 kilowatts! That's more like it. So unfortunately, if your build STRICTLY requires a continuous 200 amps, this controller (while otherwise quite a good buy) will not do it. Stock, I would guess 200 amps would only last for 8-12 seconds. The only other "gripe" I have with the controller is the micro USB port. After using that multiple times for programming with my computer, it BROKE off! I was stranded... until I bought the bluetooth module. Luckily, the Baud rate and firmware version that remained "bricked into" the controller talked to the new bluetooth module correctly. I was able to program it from then on with my phone (which I may say is a FANTASTIC buy, even though it is about $40-$50USD).
All in all, I do recommend this product. Just don't expect the level of performance it suggests, and be careful with the USB port! If you want to see it in action, check out my YouTube channel: Marcus Herold . I have 2 videos up as of now which are "Ebike vlogs" on my bike using this controller. "Riding with Nate!" is a much more comprehensive review because you can see much more details in the programming. I plan on uploading a video in the near future of the heatsink mods I made to it. Good luck with your projects!
