Vesc is one of the best available controller on the market, Small size / High power / Advanced features. If you want to mod you scoot then this is good start, but on the market we got couple different versions so let me tell a little bit about them.
Vesc 4.12 Anitque , but still work
Vesc 4.2 Great start
Perfect for low power but advanced projects, Like Ebikes / Esk8, Escoots etc..
Max safe voltage is 36/42v so 10s battery & not more than 50A /1500W . Risky but should work with 12s so 43/50,4V & not more than 35A / 1500W.
Vesc 6.6 Insane power and features for the price
Max safe voltage is 12 so 43/50,4V & not more than 100A / 5000W ( I tested it with peak 300A 6KW per motor and was working quite nice 🚀 ) . Risky but should work with 13s so 46,8/54,6V & not more than 80A / 3000W.
