But how many days? 3? Assuming 3, do you suppose 3 trickle chargers would be cheaper than a 45 watt panel and converter? Just a thought. --- On Fri, 1/21/11, Justin Wilt <sunbugone@xxxxxxxxx> wrote: From: Justin Wilt <sunbugone@xxxxxxxxx> Subject: [tcb] Re: Question About Dual Battery Set-Up And Solar Panels To: tcb@xxxxxxxxxxxxx Date: Friday, January 21, 2011, 5:08 PM If you park the bus for a long period of time (in the sun) a trickle charger will help keep the batteries charged. But you are talking about output in Milliamps, this will take days to charge a depleted battery On Fri, Jan 21, 2011 at 4:04 PM, kelly dosch <kellydosch@xxxxxxxxx> wrote: Man what shows are you going to? I wouldn't mind a free solar panel! And I was actually just wondering if just a little trickle charger panel would help much. They're so cheap I might just try one. Thanks again for your time.

They can be used as a trickle charges. If you are looking for a second battery, go to a battery rebuilder’s shop and buy a rebuilt one for $50-$60.

I need to get a deep cycle RV battery for my Westfalia Campmobile. I'm seeing about a gazillion types with vastly varying prices. ($120-$600!) Is it really all that complicated or can I just get the cheap Sears Marine/RV battery? ($120) Also, I have noticed a lot of Westies with solar panels. Why? If they have a campsite with electrical hook-up the battery can charge itself. If not, the alternator will charge it during a short drive. I don't get it. Why would anybody want to drop $400 for a solar panel? (Tell me it isn't just to be "green".) Thanks for your time,... )< (- (_ (_ `( -- Justin Wilt Technician Post Oak Motorcars Rolls Royce Motorcars Houston Bentley Houston 1530 West Loop South Houston TX 77095 USA +1-713-850-1530 +1-713-539-4419
