Red face External/extra battery to power stereo

Has anyone installed an extra battery to power Boss MC500 to avoid stator issues?

Your referring to a battery that would not be connected to the charging system right?
Don't see why you couldn't.

It could be hooked up switched also, so you can switch from one to the other for charging....

You could but you would have limited power without a way to keep the additional battery charged.

and always remember, "Ride until you rot!"

but having to face the fact that this is a lifetime routine
going forward. Five operations done and it still continues.

Wolfie, I guessed they missed the switched dual batt system. I had one on my truck ( homemade of course) I used for hunting/camping

I realize that would be a drawback.
I wonder how much juice this radio of his uses anyway?

hmmm that is an awesome idea. Might have to investigate that. Building a sissy bar for camping and have a 2 liter fuel bottle I was going to mount back there, might do a battery too!

I know that a lotta RVs have aux batteries....and there is an automatic switching system....I had one on my tourney bass boat...switched between charging the engine starting battery, to charging the trolling motor battery...that could be something to look into....the way the bass boats do it....Im sure its compact.....I think I had something the size of a solenoid unit on my Skeeter....

And ya, a normal stereo wont draw much and say, a TP stator with a higher upped R/R could handle it (MOSFET)....Unless ya have the Joshua Light Show eminating from yer bike....a TP coupled with a higher amp MOSFET should handle it....
Or ya can add a Chevy alternator belt driven off the stator side, as was just shown here recently.....(I still crap my pants every time I look at them pics, lol)....fookin genius though....

And Tommy...Vulcan2000...call me when ya get a chance....its time to ride brother....

switch your running and blinker lights to LED's and you will be very surprised at how much extra Juice you will have. check my sig.

Now, not knowing the current draw of your stero setup, it may still be overtaxing the system with a stock stator and Regulator.

Some details would help, but you can find a good balance between current draw and having to bleed extra current through the R/R by making some adjustments in your system's power consumption.

EDIT: It is possible to set up a secondary battery and throw a switch so you can charge it at highway speeds, but you need to make a few calculations on what your system is doing and what (if any) excess power you have available at higher RPM's.

Specs show RMS @ 300watts... I do need to switch to LEDs, though the stories of having to replace the stator are making me consider adding an extra rechargeable battery...
