Hi,
Just wanted to post my experience using a christies charger. I have a 78 series, with 1 starting battery and 3x50 amp excide orbital deep cycle batteries. The deep cycles are wired to a 175 amp anderson plug which is located under the back of the vehicle. I have the 3 hp 80 amp model charger, the 55amp model was just to noisey.I have changed the connection on the charger so it just plugs straight in to the female anderson plug.
The charger is louder than say a 10i honda, but still reasonably quite. I run two fridges + a few other gadgets. The charger provides enough power for our needs each day with a run time of aprox 1.5 hours.
This is great, not just for us but if we have camping neighbours. No endless noise of a generator running all day!.
We are really happy with it!.
If anyone would like any info give me a bell.

Sounds great Lynon.

We are quite lacking generators optimized for 12v charging , and heres a real marketing opportunity there.

Had any issues with overcharging - mind you I use same battery are they are the most tolerant of any sort.

Do you monitor them at all volts/amps etc

Robin,
The Christies is simply a 55W or 80W Bosch alternator mounted on a Honda motor. The internal regulator regulates voltage, same as in your car, but I think Christies also gives you the option of boosting the regulated voltage to 14.7. So it can recharge a bank of 12volt batteries in quick time.

Hi Robin
No need to monitor amp/voltage, it does it all, there is a led display which gives you this info. The machine adjusts the charging rate automaticly, so you can just leave it to run until it runs out of fuel if you want. It won't over charge. Not much good for wet cell batteries as they won't take a quick charge, it will still work but will take forever. Best suited to AGM's or Gell cells. It cost 1350

Mike,
Its not just the charger (80amp alternator) - there's a Honda motor attached!

I appreciate that. But this thing's only purpose in life is to charge a battery.

Same price as 120W of solar panels, and recharges 10 times faster.

Depends on how you're setup. I'd like one - everything I use runs off 12 volts. It uses the same fuel as my stove, so it would suit me. And you'd only be making noise for 1 hour a day.
