Does anyone know if it's possible to hook up a second battery to an S40?
How about an inverter? (Someone gave a 400 watt inverter and I have no idea what to do with it).

Yes, you can add a battery, connect it in parallel. YOu'll then have more current capacity. What youd effectively be doing is, strapping a battery & inverter to the bike, so you can use the bike as a charging station for a 400 watt ac power supply. You need ac often when youre on it? Id separate the batteries if I was using the inverter, so I wouldnt risk draining the battery I need to start the bike. A simple switch would be fine, The charge system isnt gonna shove so much current thrui it as to burn a switch up, Dont get a mini switch,, get one thatll handle the output of the charge system,, it isnt that much, I wouldnt mount that to the bike, Id build a box for the battery & ionverter & hook a pigtail; to the battery on the bike, so I could plug it in.

 
      so you can hook up your battery charger ??

Brilliant idea!! Charge one battery off of another! How'd I never thought of that...

I thought I would make some saddle bags out of ammo cans and put the extra battery and inverter in one using a watertight thru the wall conduit connector to run the wires. I'd put he switch in there too.
Why?
I don't know---but I'll think of something.
Right now, I'm working on a backpack rack that hooks up to my sissy bar.
Maybe  a long trip---I could put my TV
in the other ammo can.

If you must watch TV, just use your Droid.

Seriously, a 400 watt inverter on this bike is too big.  
 -- These things have an efficiency of something like 80% or so.  
 -- A 400w inverter will surge momentarily to around 800w when a load is hooked up.  
 -- 800w with an efficiency of 80% equates to 1000 watts.
 -- 1000 watts at 12 volts is over 80 amps.  Ask the gurus here what an 80 amp load, even a temporary load, will do the charging system on a Savage.
 -- At a steady 400w output, that would be a steady 40 amp load at 12v.  (way too much for a Savage charging system)

Use the 400w inverter in your car.  Forget about it for the bike.  If you really need 110v on the bike, use a tiny inverter or bring a loooooooooooong extension cord.

I like this approach!! I'm with you to the end! But inverter... let me know how and what for it worked out, I might hook one up too
