Net result is you can do better, but it can be done. The power board people are dependent on managing lightweight controllers, bikers are not.

The one link is about modifying a throttle with a servo tester, the controller says it has a bec. But those things blow up.

No. You will need to hack something together using a potentiometer-based solution using an RC "servo-tester", which delivers a TDM (time-division-multiplexed) signal to the RC ESC.
Ebike throttles cant even be used as an organ donor for a poteniometer for serv0-tester because they are hall-sensor based.
Some older proprietary scooter throttles are simple potenciometers....maybe you can find one of those?
....and yes, BECs can blow up with higher cell-counts. Linear 5V BECs are really only good for 5-cells or less....otherwise risk problems. Maybe disconnect one of legs of BEC 5v regulator to avoid problems?

Thanks I decided to go for a 50amp ebike controller to keep it simple as someone i know got one of the vesc controller and it blew after 5 minutes of use and supplier refused a refund . I got a bafang geared hub motor overvolted to 48v with 30amp controller and got speed of 38mph and 20 mph up a steep hill just wanted more torque for wheelies now got a 24" rim and with the 50amp controller hope it will wheelie easy

‘Wheelie easy’ is a matter of geometry.
There is a limit to the power you can feed those small geared hubs, before they start stripping gears and damage clutch.

Work on the balance of the bike. Buy a laid back seat post, DM stem... shifting your cockpit 2 inches to the rear will make your bike much easier to wheelie.
Make it fool-proof, and I will make a better fool.
