Razor MX650 newbie

 Hello ESP! 

I recently purchased a used MX 650 that I'd like to upgrade.  I currently have a generic throttle I previously purchased that has a volt meter (See attached picture).  I have 4 12v 12ah batteries, looking to power the bike via the pretty standard 36 to 48v conversion. 

I'm now ready to purchase the rest.  After spending a lot of time reading through the forums, I think I'd like to go with the 1500w brushless motor, a 48v controller, 48v charger and looks like I will also need to upgrade the chain, and rear sprocket.  Lastly, I think I'll need the correct and best options for wiring the batteries together.

Do you think the 1500w motor is the way to go for a substantial increase in speed and torque or do you have another recommendation?

I'm not planning on going to lipo batteries, sticking with the standard razor type lead acid batteries for now.

Thanks so much in advance for your help!

Thank you!
