I am going to start of this post by addressing those who are contemplating on getting Enertion’s VESCs… DO NOT BUY THEM.
Let me explain:
I ordered two enertion vesc back in December and got them in February. Plugged one of them to my laptop and did a motor detection, got it running and ready to plug it to my board. Finally the next day I got my board ready and connected all the components. Got the board running for about 45 min. I was riding at a relatively low speed (around 15km/h) considering it was my first time on a Esk8. All of a sudden my bord stops aggressively and i go flying. Came back home with some bruises but nothing too serious. Messaged Onloop and posted on this forum about what happened. I got told to check for possible errors on the bldc tool and i did so. I then discovered i had a Drv chip failure. Asked onloop if i can get a refund but unfortunately he said no as it wasnt covered under their guarantee and claimed that it could of been the users fault and not theirs. As a newbie I thought he might be right and i might of accidentally did something wrong. I naively did nothing afterwards.
Now onto the second Vesc from December. Did the same procedure (pluged it to Bldc and did motor detection) with extra care. Plugged it to my board and lasted me for about a week. Keep in mind that that VESC well protected with no possibility of shorts happening. And again the same god damn drv failure.
NOW… what brings me to write this post.
Even with these two vesc failure i decided to buy another two vesc from enertion as i wasnt entirely sure if these failures were caused by the manufacturer or the user. So went ahead and order two vesc in May and guess what… got them 4 months later in August. Thats fine, i dont mind waiting but every single time enertion kept pushing the shipping date… WTF.
Anyway got them finally. Plugged one vesc to the bldc tool and couldnt get the motor to spin right. I later realized (with peoples help on this forum) that i had the wrong bldc version. So i then downgraded the bldc tool and got my vesc to work fine. Plugged it to my board and everything was fine. I decided to put some heatsinks on three of the mosfets just for precaution. Rode the board for exactly 8 days with medium use. Everything was fine until tonight when i decided to go for a night ride. Pluged everything, went outside and rode the board for a minute until i started to notice that the board was jerking. At first i thought it was my transmitter that was causing that due to signal interruption but a few seconds later the board wouldnt move even with the transmitter and receiver signal very strong. Got home, inspected everything only to see three red blinking light. At that point i knew for sure it was an drv failure.
Now before anyone asks me about my set up for all of the VESCs, i was using 10 cells 5000mah batteries (2 turnigy nanothech), a 6374 sk3 149kv motor and a hobbyking gt2b transmitter.
Now i am not in anyway trying to bash or insult onloop as i am fully aware of his contribution in this community. His ESK8 Hardware seem to be of good quality even though i have never bought a motor mount or a pulley but see good reviews on them.
HOWEVER i am going to say that enertions customer service is the absolute worst customer service i have ever come across and their vescs are extremely bad quality. I had to wait 4 months and pay over 450$ that i will never get back on a product that fails every single time. And i dont mind if he is in his garage trying to get his company to grow but do not tell your customers that you will ship their product on date x but end up shipping it 4 months later. Now i get it that you might run into some complication along the way but you are fully aware of those complications and instead of giving a shipping date, at least give your customers a heads up by saying that they might not get the product by x date.
And people…Keep in mind that I have never given a bad review on anything i ever bought. Its fair to say that i have been patient with enertion by not blaming them about the first two vesc failures but instead made sure that i wasnt the cause of the problem first before writing anything negative about their product.
I am sure some people who bought enertion vescs can agree with my statements.
I am trying to save people’s time and money here. And i am speaking from experience.
