Hi woolley,
The standard electrical system on my MK 2 is pretty good. It is well regulated and the cylinder shaped thing behind the headlight is a capacitor that also smooths the DC output. Theres no reason not to run a GPS direct from the bikes DC system, the MK2 puts out between 13.8 and 14.8v, depending on revs. Any of the automotive GPS and Garmins will happily run on that.
If you are fitting a battery, Id suggest definitely sourcing a 'dryfit' lead acid type. these are sealed for life, can be mounted any which way up you like and no acid to leak out. Id not recommend fitting much bigger than a 6Ah capacity, as when its flat, a bigger battery may overload the system by trying to draw too much from the stator. Id also not advise running the lights and trying to charge a flat battery up..same problem. You can get batteries in Maplins. Also get an inline fuse holder and rate the fuse at 5amps. That should protect the bikes system from an overload by the battery 'asking' for too much.
There are also 'Cyclon' type batteries available. These are a bit pricier, but are very robust and will survive long periods of no charge without suffering. They are also not too fussy how they are charged.
Dont go for Ni-MH or Ni-cd types. These types have quite specific charging requirements involving fixed current limits and variable voltage charging that the CRM system just wont provide.
If its a 'back up battery in case' type of fit, you could just fit a standard car cigar lighter socket somewhere (boat chandlery shops offer 'marine' grade sockets that are much more robust than Halfords or Maplin special), and have a lead so you could just plug the battery in for an hour while running, then unplug it and tuck it back in your bag.
Hope this helps

Yes i fitted a battery to my crm i got a dry cell battery and fitted it to the bike made a box up that fits under the seat behind the air box and wierd it up to main earth lead on bike and to recticfer so when bike is running it will charge up battery and will run of either battery or the main bike electrics i got my battery from a company called MDS batteries they advertise on the web and it only cost me a tenner .

Hi KK,

Just been reading your post with great interest. I have brought a sat nav but the battery only lasts around 4 - 5 hours so it’s not long enough for a full days trail riding. I started looking at batteries and different sizes and where I could mount it on the bike. After playing with a very neat 12v 1.2 AH I decided that the battery would have to be a lot bigger and thus heavier. I've been out riding all day and decided that I was going to try running the sat nav directly of the bikes electrics and see how I got on.
So, after a quick look I found your post and it looks like I'm on the right track!
My only question is where to wire into? I have a cigar type socket so I just need to pick up a 12v feed and an earth.
Any help would be useful.
Thanks,
