The motor i have no clue as i didn't take anything apart all i see is Maximum current 22+


First I wanna know what max battery can i buy without upgrading anything with it being the way it is now. could that battery be used or maybe a 30Ah or higher? only difference i see is the: Cell Combination: 13S8P the one installed on the scooter now is 13S4P is there a difference between those two?

Robot or human?

Second what could be the max battery and max motor with a digital speedometer and anything else needed besides those two items could i install on this scooter in the future. In a way kind of like scanning your computer to find out the max parts you can use that's what I'm looking for!

I'm looking for longer use(more miles per full charge) and maybe little more speed/power if this is at all possible!

Thanks to anyone and all that could help me on this! Please don't give me wrong parts that will explode or something as i might have a young child ride around for fun but this is mostly for my transportation use!
