Thanks so much!! You guys are great!
It is normal to get a spark when making the final battery pack wiring harness connection. We drew a wiring diagram specifically for your Razor EcoSmart electric scooter which can be viewed on this page: https://electricscooterparts.freshdesk.com/support/discussions/topics/1000088621

I know...there are about 100 discussions about this, but I am likely the most electrically challenged person on this site.
My daughter will be getting an razor mx650, 17mph+- for Christmas and handing her razor dune buggy down to my son.
I need the 24v dune buggy to go close to the speed of the mx650, BUT, I also need it to have a long run time and good torque.
I am considering dumping the old 4 year old batteries and installing 3 new 12V batteries.
I would like it to fit under the same cover. Any suggestions on batteries that will fit that are cheap (maybe a 3 pack of the 12V 15ah batteries for the mx650)?
Also, I know I need a new charger, which 36V charger will charge 12V batteries with the same plug-in that used on the dune buggy and work with 3 batteries up to...say 15ah?
Do I need as high as 15ah? Will the 8ah be OK, or would 10 or 12 be better?
Last thing. I seriously need an idiot proof diagram of the wiring instructions to add the 3rd battery to the current set up.
