Seems like a waste of money to prove: "If you build it, they will come".

Simple solution > If your chassis batteries and your house batteries are in the same compartment like my last two motor homes were/are, just run a wire from one hot on the house to a hot on the chassis. Not to jump start anything, just to have power from the Battery Tender to both banks.

Hi Mike Canter,
For those without skill it is an easy way to charge all the batteries at once. The Quad Link is just a pass through device. One would connect the Quad Link to the chassis and the house batteries just like one would connect the charger itself. Therefore, a single 12 VDC charger will work just fine.

If you are not in agreement, there is no sense continuing the debate. We can agree to disagree.

Hi Dunner,
There are coach owners who, for a variety of reasons, can/do not want to get technically involved with running wires or making home made solutions. Buying one's way out of a problem is a valid answer for those taking that solution. RVing is a great way of life and every solution should be honored for the purpose and target market it serves.

Gary, one of us are not reading that correctly. To me the Quad link hooks up separately to each house battery then charges each battery at Max amount then switches to another battery in the bank. Each battery is a 6 volt battery so if you charge one at a time you need a six volt charger. Now you could hook it up to the WHOLE house battery bank and to the WHOLE chassis battery bank and treat them as two 12 volt batteries and have it switch back and forth between those two banks then you would need a 12 v charger.

Gary, If some consider installing a BatteryMinder as "technical", they can have a qualified technician install it and all they would have to do is plug it in. Is that too technical?

A BatteryMinder® "Charger-Maintainer-Desulfator-Conditioner" is far from a "home made solution". I consider a BM a better option than a Battery Tender®(Sorry Mike).

I find it offensive that you refer to my idea as a "home made solution".

Maybe he meant your idea is better. In the food industry, home made is best

I have two battery minders and love them. I use them on all of my batteries from the motor home to the Garden Tractor and Pick-up while they are in storage. I like the fact that they de-sulfate the battery while they are charging. I would like to get three more for all of my batteries so I do not have to keep moving them around all of the time. I do have other smart chargers that rotate with the battery minders so all of the batteries are keep at their peak voltage. As for the trickle charge I bought an Intellitec B.I.R.D. 2 for my batteries as it will charge both battery banks no matter what bank is being charged. I liked the bi-directional aspect of that piece of equipment. It was not hard for me to install. Good luck in your choices.

I have 2 - 1 amp - 12112 BatteryMinders for my truck and sandrail and a 12248 for the MH. I've had the 12112s since 2003 and recently bought the 12248. I really like it with the 2, 4, 8 amp choice and the Gel, Flooded and AGM option, plus it is for up to 6 batteries.

I also have three other smart chargers.... someplace.

I just checked Battery Tender and couldn't find anywhere that they desulfate batteries.

Dunner, just looked up that Batteryminder and it sure looks better than the Battery Tender on the specs plus the desulfation mode is better and will refresh the batteries.

Not sure Mike, but I think the Tender came out first, but they never advanced their technology to the desulfate mode. I need to put my scope on a BM and see what happens when they go into the desulfate mode. Suppose to pulse a high frequency something or other when it does.

The big Batteryminder says it can charge six batteries in a bank also. So for sure it can do four. That Model 12248 looks like the Bee's knees and only $108 through Amazon.

I use the two bank Battery Tender. One side for the chassis 12v AGM battery and other sie for 2 12v AGM coach batteries. I also use a two bank for my two motorcycles, one with AGM battery and one with wet cell battery. They have been in use two years and work perfect. I bought them on Ebay.

I buy all mine from Battery Mart and paid $109 for the 12248, with free shipping. It also comes with a temperature probe. It says not to extend it, so I put mine between the slump block wall and the siding, on the west side, where it is mounted in my garage. I have an "umbilical" cord that plugs into my MH.

When I went to get my new tires, the installer asked: "What is that". I forgot to unplug it and was trailing 10' of cable. Gotta put that on my camping check list.
