power wheels too much power? Answered

so here da ting. i got a little 6v power wheels quad at a yard sale for dirt cheap. i figured hey why not ill work on it a little and make it nice. long story short, i ended up with two 18v harbor freight batteries hanging on each back fender like military ammo cans and it looks awesome but now its a little too scary to let my son ride it. i would like to put a voltage regulator on it to turn it up or down depending on how well he can ride it and how safe i feel he can be. most of the ones i have found can barely handle 2 amps. where can i get a regulator to handle the load continuously.

p.s. this is the last part i have to figure out before i can make a full instructable.

You can also take a rated speed controller like for a scooter and modify with with a resistor.
The handle is usually mothing more than a fancy potentiometer, adding the right resistor in series will limit the output - if in doubt with a key override ;)
But I fail to see how 6V motors will survive on 18 or even 36V....

Run the 2 batteries in parallel - This will halve the speed and double the range.
