smganger Report post Posted July 1, 2020 I have recently purchased a 1994 Seven Seas By Cobra RV. As I have spent some time getting familiar with the systems, I have discovered that I can not find the cabin battery(s). At all. I know I have one somewhere and it should be easy(?) to get to. An assumption that I am making is that the battery would be in an outdoor environment, and will not be located within the living space. I have opened all I have disconnected the chassis battery as a last resort (hard to tell what some people will do for a quick fix). Thoughts? Share this post Link to post Share on other sites
kaypsmith Report post Posted July 1, 2020 In a class C, the house batteries are sometimes under the hood, not sure about your brand MH, but worth looking there for them. Welcome to the forum and maybe somebody with more knowledge about Cobra will come along soon. Share this post Link to post Share on other sites
wildebill308 Report post Posted July 1, 2020 Welcome to the forum. Is it a Ford Chassis? Look Behind the drivers door in the house part is a drawer holding a very large D8 house battery, Maybe. The start battery is on the driverside. Sometimes they used the passenger side for a house/deep cycle Battery. Good luck and let us know. Bill Share this post Link to post Share on other sites

smganger Report post Posted July 1, 2020 Thank you for the replies. I am on a Chevy G30 van chassis. Driver's side holds the chassis battery. Passenger side has A/C components crammed there. There is nothing located at the steps. There is nothing located next to the generator. Lastly, I have accounted (I believe) for all of the compartments outside the house to the inside as well as looking at the underside of the chassis to see if there is an additional space not accounted for. I am stumped. Share this post Link to post Share on other sites

hermanmullins Report post Posted July 1, 2020 May sound dumb on my part but have you checked under the bed? Some Design Engineers are sadist. Herman Share this post Link to post Share on other sites
smganger Report post Posted July 1, 2020 I have opened everything I can on the inside. It there is a space that I can not get to on the inside, there is a corresponding storage space, furnace, h/w heater, refrigerator, propane tank, generator, rear wheel wells I have located said battery. It was indeed, Herman, located under the bed. I had to reexamine the space utilization there, and move the wood platform the bed sat on (It is two piece plywood hinged in the middle for access) that I thought was screwed down on the back side. This also explained the a hole in the back of the house (which went to the battery box to vent gases from the battery). Thank you all for your help and suggestions.

wildebill308 Report post Posted July 1, 2020 Glad you found it. I have never seen the batteries under the bead. How maney? I have usually found water tanks under the bead. Bill Share this post Link to post Share on other sites

Herman A little off subject, but since the OP has now located the battery location! The first time that I or many in out neighborhood had seen a VW beetle, I was driving a bread truck back then, (early 60's) one customer had just purchased a new one. She proudly told me how amazing that little car was, including that it did not need or have a battery. I told her that was insane, there had to be one somewhere. Nope she replied, her husband had checked all over and there was not one. A year later, she met me at the door to inform that the battery had been located since the car was burned to the ground, the battery was under the rear seat and another couple rode to church in the rear seat, hit a bump, the battery shorted, and now you know the rest of the story.

jleamont Report post Posted July 1, 2020 Wow, under the bed is a new one! Our C had the water tank and pump under the bed. Believe me there was no flushing the toilet in the middle of the night without full hookups Share this post Link to post Share on other sites
smganger Report post Posted July 2, 2020 Just one battery. There was a fresh water tank, water pump, h/w heater, and an outside storage cubby, as well as the battery under the bed. The cubby and the tank formed a blind corner, a perfect place to hide store a battery. Share this post Link to post Share on other sites
dickandlois Report post Posted July 2, 2020 Now that you have found it, I will see if one of the OEM 30 Series van manuals have an electrical circuit that might cover it. Quiet common for them to come with a 2 battery setup. Rich. Share this post Link to post Share on other sites
manholt Report post Posted July 2, 2020 (edited) Is that a 12 volt battery or a 12v commercial? Edited July 2, 2020 by manholt Share this post Link to post Share on other sites

The cubby and the tank formed a blind corner, a perfect place to hide store a battery. Any chance you can squeeze in (2) 6 volt batteries? Most 12V batteries are larger than a 6 volt (physical size). Just thinking outside the box, you might need more amp hours that (2) 6 volt batteries will provide. It really depends on your camping plans. Share this post Link to post Share on other sites
wildebill308 Report post Posted July 2, 2020 This might be the perfect spot to use a Li battery, no outgassing, fast recharge, more usable capacity. The only negative is the cost. Bill Share this post Link to post Share on other sites
manholt Report post Posted July 2, 2020 Yea, $900 to $1,100! BIG Negative! Plus side is that cost is going down. Share this post Link to post Share on other sites
smganger Report post Posted July 2, 2020 I will be relocating the battery(ies) to a storage compartment next to the existing battery location. I want Li batteries since we do a lot of boondocking, but the cost is really prohibitive.I will hook up an amp meter to the battery for the first few trips to see what kind for draw I will be dealing with and a adjust my battery purchases accordingly I will probable start with (2) 6 volter, getting me some decent ah (adding to that if needed), add solar for recharging, then add li battery as the last piece of the puzzle. Li batteries will probably be 3 years out or so. Share this post Link to post Share on other sites
