Using a voltage reduced to charge aux 12v battery

Sulli017

I'm getting ready to add a stereo and 12v auc plug to the cart powered by an auxiliary 12v. The problem is I don't want to have 2 chargers going on with 2 wires, 2 appliances and such. Is it possible to install a voltage reducer to my pack to charge the aux 12v while the main 48v pack is being charged? I realize this is a small draw but don't want to have any impact on drive time or add another charger to the mix.

Is this even possible?

Sure is possible but it is not practical nor is it going to be recommended as the output of the 48/12 is not well regulated and to properly charge a battery you need very well regulated voltage as well as amperage... The playing of a stereo is not going to adversely affect your range unless your planning on pumping up the volume with amps and subs etc.... Lets look at it this way are you currently having issues with the cart and its range? Are you traveling 15 to 20 miles or more per usage?

I'm a new owner so I have only taken a few trips, but I plan to use along 30-A in Florida which would require a heavy dose of ah. My thought was a couple 5" speakers so it would not be a ghetto blaster but I'm trying to keep in mind the lower you go on your pack the less life you get out of it.
With that said, if it saves me 2 miles that may in the long run get me several more cycles on the pack before needing replacement.
I get you comment regarding the regulation and I guess there's no easy way around that aspect without $1,000 investment is needless equipment.

The thing is a 48/12 would not save or cost you anything by way of true cycles, just listening to some tunes at normal volume and charging your phone etc will draw very little. Yes a battery only has just so many full cycles in it before performance by way of life is affected. BUT the best way to get the most battery life is to properly care for them and when not in motion plug the cart into its charger and keep them fully charged as much as practical... Better yet protect your battery investment with a smartcharger from DPI the Accusense charger keeps a 24/7 float charge going to your batteries... As an example my batteries are 2 years old, hold better than expected 100 % rated voltage even after several miles of use and have yet to need any water...

Perhaps I'm thinking a bit too cautiously...or over analyzing the options because it would be fun to put together. I'm keeping it in a 24/7 float right now so I guess I'll drop the extra connections and move on

Sure I understand... I regularly over do one project or another just cause I can or it would be fun etc.... Just keep in mind the old adage of KISS the more complex it is the more likely it is to screw up and usually at the worst possible time....

I have a Powerstream voltage reducer. It is very well regulated. The output voltage can be adjusted from 12 volts up to 13.8 volts. I would think it would keep a small 12 volt battery topped off. But you are still taking away from the main pack. But this would give you complete isolation of the 12 volts. Then again the Powerstream is fully isolated.

Love it, Mr Golf!
