Boondocking and 12V Systems

All,

On this, as well as several other RV forums I try to follow, there are numerous threads about issues with batteries and boondocking. I've written several responses and am getting tired of writing To that end I wanted to start collecting the information in a single location. I've had a more or less unused blog site for a while an decided to write it up there.

Factory RV 12V Installations and Boondocking

I have a lot more work to do, but wondered if some of you could take a peek at it and give some feedback?

Thanks all!

-Chak

This looks like the start of a very detailed version of DC for DUMMIES. I personally like it and will benefit many of us. Thanks for the work and I am looking forward to additional info. I currently use a Deep Cycle Marine battery and am considering adding a second battery into the system and was wondering if the Convertor/Charger will support charging 2 batteries. Run from the charger to the batteries is less then 6 foot. I just plan on piggy backing the second battery off of the first battery. I beleive this is OK as the batteries are identical in size, and age. Any advice or should I havethe fire department standing by? I plan on a fuse between the first and second battery of the same amperage of the fuse on the primary battery. Probably not necessary but would like the peace of mind in the event of a chaffed wire etc.

Hey Chak,

Nice write up, but the way I figure it 1.7% of 12 VDC equals 0.204 VDC, not just over 2 volts.

Thanks for catcihng my goof on this one. A decimal place makes a huge difference! I fixed that goof....

I'm finding it hard to articulate how minor changes in voltage at the batteries from the converter reflect into how much time it takes to charge the batteries. It is VERY significant. I'll get it

Thanks for catching my error!

It's a good write-up, Chak and I am glad SmokerBill set you straight on the percentage.

What you might consider adding is a simple diagram on series and parallel wiring of batteries (6V vs. 12) so folks understand. That would address Graybeard's question too.

No problem Chak! With my setup it seems like it takes an awful long time to get the batteries to a full charge state. I have 2 group 27 marine batts and a Honda EU2000i generator. I'd guess that the distance from batts to converter is about 20 feet on mine. I'm going to pull out my meter and measure the voltages at the converter outputs, and at the battery terminals next time it's charging to see what the measured voltage drop is.

Just a question...wouldn't this be seen by more people in the Boondocking section?

Yep - there are 2 parts too it. The 2 stage converter is a slow charger to begin with, then couple that with undersized/over length wire and you end up with a LONG charge time.
