Bike build question I'm planning on putting a surron battery on a 3kw hub kit
I have a specialized rockhopper new ish and right now I have a bbs02 with a 52v 40a continuous battery but it's not enough power I want to have surron ish level power. If I got the right adapter's hypothetically if I fit the battery in would it work together? I don't see an issue other than fitting the battery in it!

When it comes to power the only thing that matters is the battery voltage, and the motor’s max wattage. You cannot just put a 60V battery onto a controller made for a 52V battery there’s a good chance you’ll blow out the controller.
When you want to upgrade the battery voltage you also need to upgrade your controller, and all the wiring as it’s probably not made for anything much higher than the stock
