Okay, So I May Have Got A Little Over The Top .

[/IMG] Hi all,

So, as I tend to do a lot of bike camping I find it hard to charge things on the go. Cameras IPhone iPad etc. So I decided to put an auxiliary battery in the top box on the bike and run a split charge system into it to charge the battery when riding. I wired my rear camera into this and two battery chargers for my drift cameras as well as 4 usb carrying ports. All this runs off the aux battery and also charges the aux battery when the bikes running and the aux battery is fully charged when I arrive at my camp for the night. I put it in the top box so I can leave things charging and locked away from prying eyes if Im not on site. So Far Ive managed to get 4 full days charging before the battery gets too low. What ya reckon?

Ok so Ive completely buggered posting the picture, hopefully its here...

Nice setup. Never enough power!

Looks sweet and sounds like it does the job. Now you need to come up with a way of mounting something like that inside the non-existent space under the pillion seat of a sport bike

Got there in the end, sounds a great idea. And the charging items can't drain the bike battery?

 

[Viscount]

nope. the aux battery is charging when the bikes running but as soon as the ignition is turned off its disconnected from the bike. So it can go completely flat and the bikes not affected

Cool idea and setup.

I'm no electrical engineer, but did you check to make sure your strator/magnet coil/rectifier is adequate to provide charging to two batteries while on the go/engine running? Some are not meant to have a high output and doing so would damage or fry the stuff I mentioned earlier. It pays to check your readings and make sure your bike's charging system is not being overloaded, damaged parts or electrical fire is a possibility.

Hi. Yep. The alternator chucks out just over 14v and very thing else is designed to support that voltage. It's all wired in with a prewired relay split charge electrical system I purchased especially for this purpose. There are also two electrical sockets on the system from standard which I don't use which helps . 14v is more than enough to charge both batteries I think and the system I put in has numerous fuses just in case. It all seems to be working fine but I will keep and eye on it as you never know.

And on the plus side I can still fit the tent in the top box

That's impressive actually. I guess it's how your regulator deals with it but I guess as long as the bikes getting 14volts and not struggling to get it, should be fine.

Well thought out

All depends on how much redundancy was built into the system in the first place. Maybe check the ref for heat when you have been charging both for a bit.

Very well done sir
