Looking for some recommendations about upgrading my escooter either my motor and battery. I have an used Isinwheel GT2. Since a few days ago it's been overheating everytime I take a ride for more than 5Km. Yesterday opened my GT2 to check if everything was ok but I found my battery pack it's inflated, that's why I'm thinking In change the battery.

In the other hand my motor seems to be dying because now it's rising over 110°C and protecting. I'm thinking adding a bigger one so my questions are:

Can I add a 1500W~200W to a controller that previously had a 800W motor installed?

My controller it's a 21A controller

How can I know if my controller can handle more than 48v?, let's say 60v.
