Whew! I finally wrapped up my battery update. With the help of my 7 year old journeyman fabricator Zack (my son) the project went very smoothly... It'struly amazing the places his little hands and arms can squeeze into [emoticon]
Here are some pic's;

[image]
This is the configuration of the batteries. They are supported by a piece of 1/2" Finnish birch plywood.

[image]
The battery support platform is now in place in the basement. On the left is the fresh H2O tank, straight ahead is the front wall of the camper. The stiles are 2x2 clear Doug' fir. Everything is screwed and glued (w/Titebond III). Battery cables are 2/0 throughout.

[image]
This shows the vertical support (on left) in place. It ties together the camper floor (above) and the basement bottom.


[image]
This is the complete "battery box". The tie-down eyes are screwed into T-nuts that are in the support board.

[image]
The batteries were a very tight fit going through the basement access panel.

[image]
This is battery #1 installed. You can see the temp sensors for the inverter/charger (on neg' battery post) and solar charge controller (hot-melt glued to side of battery case)

[image]
I had to relocate the water pump since it was previously mounted in the location where this battery (#2) currently sits. In this pic' you can also see the hose that provides furnace heat to the basement.

Last night I re-programmed my charger according to the 3-stage profile that's outlined in Odyssey's tech' manual and flipped the 'charge' switch... The ammeter indicated a 90A bulk charge rate! When I left for work this am it was still in the absorption stage (14.7V). The last task left to do tonite is to install the new camper-to-truck connectors and run the 4ga cables from the truck bed to the passenger side starter battery (also an Odyssey).

Just in case you missed it, here's a link to Part 1.
Looks like we'll be ready for the annual X-mas Eve camping trip after all. [emoticon]
Happy Holidays!
-Mark

That's excellent,well done. That's perfect that your charger is programmable to your batteries specific charging rates. You'll actually get a complete 100% charge when you leave your house and your batt's will stay healthier. 90amp bulk charge,wow! What is your total amp hours between the three now?

Mark,
I love your attention to detail. No short cuts here.
Why does building a "ship-in-a-bottle" come to mind.
I would put lock nuts on those wing-nuts. My battery hold down wing nuts came loose and all hell broke loose in their wake.
You are now ready to hang strings of those colorful seasonal lights around the awning and burn them for nights on end.
Nice job, Mark.
regards, as always, jefe

Thanks Jefe !! As Hunter S. Thompson said: "Anything worth doing is worth doing right". Yup, it's a ship-in-a-bottle-fit for sure... but everything is completely removable and serviceable. I can even access all the the fuses and positive terminals without removing any of the batteries. As crazy as this sounds this setup is easier to service than my two 6V Trojans were (and they needed frequent watering).
Those wing nuts were temporary while I was test-assembling all the pieces, there are Nyloc's on there now. [emoticon]

According to Odyssey's 20-hour spec', it's a total of 300 Amp hours.
