Power Panel

Chaos?
You should see my field box.
Actually your set up is pretty much what I want to achieve.
The battery I found on the Bay is:   7.01" (L) * 1.38" (W) * 2.5" (H)
Weight: 3 LB.  $18.00 shipped.
Actually smaller than I had imagined, so it should fit well.
I'll make sure I bring a tape measure with me when I go to the big box store.
Thanks very much for your help.

I have heard of a few guys using a 3s lipo battery in replacement of teh larger heavier battery.

I use a 5 amp SLA lead battery. Kind of heavy. When the starter is on, the needle for the plug drops a lot when the battery is discharged a bit. I need to charge it about once a month. I have a 3 cell LiPo 2200 mah battery on a starter motor now that I have not used yet. It would be lighter but I am not a fan of the nicad glow igniters. I really like the power panels with the needle best. (except the one that doesn't work) A LiFe battery would need about 4 cells and a balancer. Some of the A123 batteries are 2500 mah. Probably good enough.

Thanks a lot for checking in guys.
Aspeed;
I found a 12 volt 5 mah battery on the Amazon site.
Dimensions: 3.54 inches x 2.76 inches x 4.21 inches.
Weight: 3.9 pounds.
Think I'll wait for  the panel to arrive from the seller. Then I'll take the dimensions to the store and scope out a suitable field box.
Probably will go with the 12 volt battery. Go with what you know.
Please let us know how your Lipo set up works out for you.

The lipo is ok for the starter. It works fine for my smaller motors up to .55, I don't use anything bigger. I have not used it for the panel. I think it may be better for taking the hard discharge over the lead acid really. Most are over 10C. Many guys (and a few girls) are using the cheap Harbor Freight or Dewalt 18V battery packs for the starters. I doubt the panels would like it. I was so tired of dead 1.2v ignition batteries that I went to the panel. I have a few of them. I recently found that the Hobbico panel was not working well. It is the older one. Not the power panel II. The needle was up in the green zone but it was a bit tired I guess. I really like the needle to indicate when the plug is good. A few times I fired off a prime ad the plug blew. It saved a lot of time crouched over on the ground.

Thanks Aspeed.
It is the Hobbico Power Panel II that I have coming.
If I remember correctly It was a motorcycle type battery that I used to use, starting up my old OS. Never a problem. Was hooked to a Sullivan starter.
I don't remember the size battery. 20+ years ago. Big mistake ever leaving the hobby.  
Need to find where that old Sullivan is buried in the shed.
The only engines I have now are two four strokes under .52 and a few Cox engines.

I need to work on my pitbox a bit. The plane-holding uprights get in the way of putting it in the trunk. The plans are floating around here someplace. I think Roddie may have posted them, or sent me a copy of his drawings.
Or they are over on RCG.
In any event, I built one end of one side to hold the panel. The battery is in the middle on one end. CL lines on spools go between the battery and the opposite end. The starter hangs on one end where it is easy to put away.
I wish I left enough wire between the battery and the panel so I could change the battery without removing the panel leads, or without charging through the panel.
Eventually I hope to power a stooge with a 12v feed and a trunk release solenoid from the battery.
I use a 12 vilt security/emergency light battery to power it.

Wow, Nice field box Jim.
Wish I could spend the time to build my own.
But, got too much on my build plate at this time.
I think that the pre-made boxes as offered by the local Lowes is what I need at the present.

Jim is that a licura flask in there Nice looking box , I have a battery out of a Honda SP mower i am wanting to try in mine( very small ) my old panel that gave up    
My new power >>

I've been switching toolboxes lately.  Got a stacking one that I thought would be good because of the wheels.  It was too heavy to carry any distance with the older one.  Used it last year, but the panel was on the bottom and it wold tip over, so went back to my old one and put wheels on it with a suitcase handle and wheels. It's the clear one with the removable starter box. No pic of the wheels yet. You can see the starter with the LiPo. I normally use the corded one.  Some others that I had over the years but don't use any more. Got a few others since but no pics.  Sometimes you buy a plane and they come with a toolbox.  The blue Hobbico panel works OK, but the plugs don't light up enough, so I changed it to the black one from the double box.  It's OK now.  I need the liquor flask accessory for the ultimate.

Got some car and boat ones too, that I don't use any more. I just got some new road cars though, so I might use one again.

Lost my old field box in the move. So now I don't have to post a picture.
Rattiest thing that you ever might see.

The flask holds six ounces of fuel. More than enough for a single outing with the Mossie on the original tanks. I just built new, bigger tanks, so I may need a bigger flask! Really.
