You should send it back and ask for a new sample, because the advertisement was misleading. I did this with my YEP 120A HV as well, which is also advertised to have temperature protection (which obviously does not work), so at least i got some of my money back. The RC industry earns a lot of money with false advertisement, making their stuff not rigid enough to withstand the specified use. Most of the RC ESC do not have correct working:
Battery current limit
Motor phase current limit
and come with underdimensioned cables.
If you ask how long it can withstand the specified current the answer usually is: Until your battery is drained. If i tell them i use 32Ah and will do this for 20 minutes or longer they do not answer anymore.
The ESC cooling today consists of some thermal pads (which are always 200% better than the standard) which have absolute bad properties in any means to connect the housing of the FET to some cooling plate or water cooling. First point is the housing of the FET, the thermal resistance is usually not specified by the manufacturer and they do not want to tell how bad it is. Next point is the thermal pad which consists of some silicone rubber and needs to be really squeezed down to very thin layer. Often this is not possible due to the bad tolerances of the cheap or even manual soldering process. The mechanics inside such cheap controllers does not allow to put high pressure on the thermal pads.
The missing ability to measure the phase current leads to frequent overload of the ESC and the leads which are always underdimensioned. As powerloss is proportional to current squared (the motor phase current, not the battery current), the situation is out of control quickly, if the ESC is underdimensioned. This missing phase current limit is also likely to destroy your motor if the ESC is overdimensioned.
Is there a solution?
Maybe. If you dimension your motors load in such way, the motor cannot produce too much torque e.g. by a reduced diameter of the prop… uups, that reduces efficiency of the overall system. Yes, with a missing phase current limit, you will have to overdimension your motor and ESC to drive the chosen prop. For model planes, cars and boats this is never a big problem: They have no payload. So the acceleration to the maximum velocity is only lasting a second or less, and afterwards the ESC and motor are overdimensioned. By adding humans as payload we multiply the weight of our drives, and while going uphill with a RC car, you can always speculate that the model will get out of sight and the car has to go down again, so the powerlosses are moderate over time. Same is true for planes: Either your model climbs so high you cannot see it anymore, or your battery is empty. If you are sitting in this electric car going up 500 meters in height within 10 minutes, everything will get overloaded if you do not limit the phase current. So all electric vehicle controllers as a minimum protection will feature phase current limit, thermal shut down with a sensor near to the FETs and so on. If such a EV controller is rated for lets say 6kW, it really means it can take it for long period, and if it is overloaded, it will cut back without getting instable. If a Seaking 130A is rated for something it does not mean anything. It cannot control the changing situation by any means, it will just put out the dutycycle you provide by your remote, aka the voltage.
This is why i use the VESC, but i must admit, it is not powerful enough and will reduce the power too early for my needs. Also here, it is a matter of cooling, at least the power reduction based on the temperature sensor somehow works without destroying anything.
Also other EV controllers could work for our needs very well, but they need the same cooling effort.
