2 12volt to 4 6volt Advice Wanted

I am going to switch from 2 12 volt to 4 5 volts. I have already cut the opening to be 12inches high.

What size jumpers do I need? 1/0 2/0 or 3/0 and how long should they be and where is a decent place to buy them?

Any tips you want share (pictures work too).......

Thanks LeeB

Don't know your coach, but look at the amperage of the fuse that protects that cable. That will tell you the maximum current it is designed to carry. Then measure the length of the cables from the batteries to your heavy current devices. You can find a table google search that tells you the gauge of wire needed.

Mine are rated at 400 amps, just as a reference point.


And I'm sure you just had a typo, it's four 6 volt batteries, not 5 volt.

The jumpers, between the 6 volt pairs, should be the same size as the original cables leading away from the batteries.

Always keep 12 volt cables as short as possible.

Here is a typical 4, 6 volt layout.

On my coach they are 2/0 sized cables. I found this place on the internet that looks good.

NAPPA auto parts will make custom battery cables. Measure post to post length for the battery to battery connections.

Hope this helps.

LeeB,
I've done exactly what you're thinking of. Long story short, we had (3) 12V so-called "Deep cycle / Marine" Interstate batteries for house batteries when we purchased the coach about 5.5 years ago. Well, those 12 Interstates were Junk. So, I changed all to, (4) 6V golf cart batteries from Costco. About $89.00 each.
As for wiring, I used the factory leads from the batteries to the coach components. As for inter-connectors between the 6 V units, I used 1GA cable. It's a very short run from battery to battery so, I was pretty sure 1GA would suffice.

Well, that setups been in there, running all the coaches appliances, TVs, microwaves, water pumps, furnaces, and a whole lot more for time stated, over 5.5 years and all has worked flawlessly. It was a simple changeover to do.
Scott

P.S. I tried and tried to link photos but, I use Photobucket and it's been getting worse and worse to use. Slower and slower. So, I'll try and link pics from another direction.

I depends on your load. The inverter and length of cable determines the size required. If you already have a factory inverter, the cables should be sized appropriately. Use the same size cable between the batteries.

On my previous 5th wheel, I went from 1 12V to 4 6V plus installed a 2000W inverter. Because of the inverter, I had to use 2/0 cables to/from the inverter and all the jumper cables. Otherwise, w/o the inverter, I could have used much smaller cables for just the house load.

Sams club for the batteries. Walmart has a good selection of connection wires.

I got the hydraulic crimper from Harbor Freight and made my own. If your interconnect wires are the same size as your original cables, can't go wrong.

You can go wrong. Most of these manufactures cheapen up where they can. You will be much happier with GC batteries as they are True deep cycle with more available power. I urge you to carefully layout your battery mounts and then use quality marine grade cables, properly crimped terminal lugs. Use 2/0 cable for these interconnections. Then you can upgrade as much as you want. You only get to build this once. I purchased my cables from; Custom Battery Cable Assembly Custom Made Genuinedealz.com and use Duracell GC from Batteries plus Bulbs. Same as Sam's club with no membership fee. Don't forget fuses.

The Genuinedealz, Inc. web site is nice. Thanks for the tip!
