Re: emmo Monster scooter, how to install controller?

No one here has a clue either until you provide more info about the controller. Make, model, pictures of what wires it has, etc. They're not all the same. How should we know? Previous controller & what it's connections were would help too.

Re: Anyone Know How to find Missing Files on a Mac?

If the drive or partition is used by both Windows & Mac it's most likely FAT32 filesystem formatted which both Windows & Mac understand.

I'd connect it to a Windows PC & try using a file recovery program like PhotoRec on it. This program is also available for Mac.

Re: Series and parallel batteries......?

You'll need 9 12V 20Ah batteries connected in parallel and series to get 36V 60Ah.

Make 3 paralleled groups to get 3 12V 60Ah batteries and then connect those 3 in series.

Or make 3 series groups to get 36V 20Ah each and then connect those 3 in parallel to get 60AH.
