What controller to buy

[Furry]

Hi all, this is my 1st post on this forum. I go by the name Furry, I was given that name in 1981. I have a 1973 to 1975 PPV (Personal Pedal Vehicle) I have added a 60 Volt 2500 Watt 11 inch hub motor up front ( It has 3 tires) and am using 52 Volt batteries to power it. Tring to make it work I used a 48 Volt 30 Amp controller to test it out before I buy a larger one. I know way to small. After 15 - 20 min the controller is extremely hot then shuts down till it totally cools down like the next day. I was told I need at least 80 Amp or more. I have been checking AliExpress and this is what I found: Do anyone have different controllers in mine or cheaper alternatives. So you know my PPV is a 2 person bike, that weights 106 lbs plus 2 X 200+ lbs (for people)

Whatever battery amperage you have decided is adequate, it doesn't matter all that much which controller you use to get there. I will note that the higher you go above 60 battery amps, the more expensive and niche the controllers get.
