Will do! Still in research mode and figuring out which controller with which connections will be ideal so as to modify the switch battery case/holder the least.
Once I lockdown the specific parts, then the long waiting game of shipping from china begins.
Thanks [mention=7554]Davy[/mention], that was helpful as I'm looking to replace the lushun controller with a KT controller, add a small display and power my front and rear lights.
