Since VESC 6.4 is out, not a single one is burnt. Thats because of all the safety updates. But that does not mean that it have to work. The VESC cuts power when getting too hot, or too high amps, or too high ERPM, or, or, or…
So I don’t think someone can answer this question without knowing what your system needs. Look at the SeaKing, lot of people are using them but at some setups they fail, at some they work.
Well, Trampa solders XT90 to theirs because they think for skateboards 50A cont is quite much and XT90 is for 90A so they have a bit more safety. But basicly you can use any connector and I would suggest 10AWG or 8AWG.
Since VESC6 the software allows much more modular hardware. So there are already Mini-Versions of the VESC (for 40V and 20A) and also really big ones with IGBTs (600V 600A) and there are quite a lot people working on versions with multible Fets for high current and/or high voltage.
So people wont be limited to 50V and only one direct fet, but e.g. 150V and 150A (post #8)
The batteries are 12S, so they are rated for 44,4V, but fully charged they got 50,4V. The VESC6 is rated for 3S-12S so that should be fine.
makes it much easier to debug too. The VESC gives you Phase and Battery currents. You can see how many amps are drawn from the battery and together with the remaining cell voltage you can calculate the remaining capacity…
