Hello

[TheOldPresbyope]

I'd be interested in your batter setup. 

Well, that depends. Cricket, rounders, North American baseball, Finnish pesäpallo, ...? Requirements vary  

I assumed Dan meant a moOde system taking power from his car's electrical system. I would think the principal requirement there is noise conditioning since there's plenty of juice (my nominally 12 V car battery is rated ca. 50 amp-hours and the alternator is rated at 50 A/120 A).

In any case, yeah, dish some details.

Regards,
Kent

PS - actually, our car is new enough to have an auxiliary USB socket. The first time my partner plugged in her iPhone to charge, we were startled to hear a track from her phone start playing through the car's "entertainment system"---what we oldsters still call the radio. That's an obvious path to exploit if I wanted a moOde player in the car.
