Need new batteries? Going from 12V to 18V or 6V to 12V? Wiring Questions?

Greetings,

I have upgraded my sons Dynacraft 12v ride on to 18v, and replaced the stock motors with Titan 775’s. The stock electrical setup is an in-line fuse connected to the positive battery lead rated at 25amps, and a thermal glass fuse rated at 30 amps on the negative lead coming from the battery. I replaced both with Bussman auto-resetting circuit breakers rated at 40amps.

My concern is that the breakers have a 12v rating. Will this create a problem given that they are connected to an 18v power source?

As a quick addendum:

I looked for circuit breakers rated for a higher voltage, but could only find fuses. Does voltage matter, or is amperage the only thing to be concerned with? If I need a breaker rated for higher voltage, could someone link one?
Thanks,
CMR

Most don't worry so much about the voltage rating on the replacement, usually the amperage is what causes a trip due to the load. More of a "load" on the batteries, the higher the current load which builds up heat causing the breaker to kick out. I've seen thermisters used also on cheaper rides, I take'em out and run heavier wiring and just use an inline fuse.
