I am going to do this for my air/fuel guage. I have an Innovate XD-16 guage and was wondering if it would be ok to power the guage itself off the sled and the LC-1 (O2 sensor) off the battery? Also was wondering how I can wire it so battery is not powering O2 sensor all the time only- when sled is running? Quote below is courtesy of MountainHorse
Adding A Battery To The Rmk's For Gps Etc
--------------------------------------------------------------------------------
Quite a few people have asked me about adding a battery to the system for powering up GPS units etc...
A 12volt R/C car ni-cad pack works great for this... Though any 12volt rechargeable battery will do.
You could also use this to power up the MFD (Multi Function Display... the gauge pack). (unplug the headlights first or put a switch on the ground wire for the HL's)
$20 at Tower Hobbies for a good quality battery pack.

Get a couple of the charging plugs too.. One to splice into your sled... the other to charge the pack with a 1 amp or less trickle charger..

Don't use the "scotch" crimp on wire splices... those end up ruining your wire harness.
DON'T USE THESE... THEY SUCK BIG TIME AND WILL RUIN WIRE HARNESSES
I will only cut, solder and shrink-tube splice... it's a MUCH better way to do things if you dont want them to fail.
This also comes in handy if you run your sled out of fuel and need to prime the pump.
Do not use the setup below to run anything that has a high current draw to it (like HID lights etc) the accessory plug does not have a high current capacity!!
Put a diode on the charging wire... It wont feedback into the system BUT, you will need to run another wire directly to the GPS unit between the diode and the battery pack.
You want to pull the positive (+) charge regulated-voltage from the Red/white wire which is powered up AFTER the engine is running... You dont want your battery charging to be a drain on the system before the engine fires... that would mess with the ability to start.
In the photo below, you will see the leftmost connector, looks like a 2 conductor trailer-wire plug.... use this as your charging connector. [This is the one under the crook of the guys thumb in the pic] It has a red/white and a brown wire in it. You can buy a mate for this plug at any NAPA store in the elecrical isle for a couple of bucks.
Pic of a 2007 Dragon ... The 2005/2006 900 and 700's have the same plug in the harness around the PTO footwell... Just make sure it has the red/white wire and the Brown wire and you'll be good
The diode, 4 to a pack, $2.50
