your car will use all the batteries including yours so therefore your car will loose power

you should never hook up a battery charger yo your battery while it is still connected to the car

i really don't see a problem with doing that....as long as you have everything wired properly.....i don't see how it could cause a problem, you're just constantly feeding 12 volts to the battery. Just make sure everything is fused, just in case.....

its not the volts that will mess things up its the high AMPS that battery charger puts out.. fine dont listen to us, but dont say I didnt warn you...

buy an extra battery for the show

 

ok well i guess the battery charger is out of the question. So the best thing to do is buy an extra battery. Anyone else have some suggestions, how to run my electronics and notharm my car or start my car?

So why do most show cars have battery chargers hooked up to their batteries? Most shows provide electricty to participants for a fee. So if keeping your car battery charged with a battery charger, why do many of the elite cars have those? What's another alternate way then instead of buying another battery?

 

yea what he said?
