Would this setup work well…[Late model Gem kit with controller, harness, and 8k motor $1800](https://community.electricforum.com/t/late-model-gem-kit-with-controller-harness-and-8k-motor-1800/26752)  
For the 12v components, couldnt I run a seperate battery like grant did?  
Or is it better to have a 5kw motor?
