Charging a battery for the trailer

So I have this nice "new" 2003 Motor Trike GL1800 conversion. And I have a Bunkhouse camper trailer. AND I have sleep apnea and a Respironics System One CPAP.

See where this is going?

I want to put a deep cycle marine battery in the trailer to run the CPAP at night, and take it out and stick it in the trike trunk during the day to charge while the camper sits at the campground IF it's a primitive site (no electrical hookup). This appears to be a good unit to hold the battery and transfer it easily.



Charging it from shore power (110vac) is easy; I've got chargers I can use. But how to charge it safely from the bike? Do I need some kind of isolator to keep it from running down the trike's battery of damaging the trike's electrical system?

Any assistance would be appreciated.

I would think it should have some sort of Isolator to limit the charge going to the battery, wouldn't want to over load the bikes alternator.

I think there are solar powered 12v battery chargers that will attach with just alligator clips for daytime charging. How well they will work on a deep cycle battery I'm not sure, they take longer to charge.

For what it's worth I use a dental device for my sleep apnea. Professionally designed by a dental surgeon to a mold of my teeth and made incredibly well but there are way less expensive alternatives out there today compared to when I got mine.

To do what you want you need a "dual battery isolater." It is a set of heavy duty diodes and a heat sink that will allow your bike to charge both batteries but not allow one battery to drag down the other one.

Thank you, NREMTP. That's what I was looking for.

Sorry, Budoka, but I know that unless I get a BIG solar panel it's not going to do it, and a dental device won't cut it for my sleep apnea either. And neither question was what I'd asked.
