Charging more than one ATV battery at the same time.
 
I have several ATV's which I use mostly during summer/autumn. I store the atv's during the winter. Every spring I go through the "buy new batteries" ritual. I keep one of my machines in the garage and use it to plow snow during the winter. I keep the "plow ATV" plugged in and use a battery tender to keep its battery charged. I have had great success keeping this battery. I would like to remove the batteries from my other machines and keep them charged as well but I don't want to have to buy a battery tender for each. Can I "daisy chain" these batteries together (4 of them) and use one battery tender to keep them all charged during the winter?

A tender is likely cheaper than new batteries every time. Just get more tenders. Otherwise get a charger designed to handle maintaining multiple 'banks' of batteries. These are likely more expensive than individual units would be.

Battery tenders come in all sizes. So, maybe yes, maybe no.

A model number of the tender would have helped.

Or just rotate the tender to each battery every couple weeks

Yeah, but a charger with some brains, that can control each battery individually, is often a better choice. Using an isolator is definitely better than NOT using one, but not really 'enough'.

I can only tell that I have 2 deep cycle batteries connected to single solar panel charger and they been sitting there fine for 2 years by now. GAte opener. So it's fine to connect several.

I can tell you the batteries are only going to last as long as they last, no matter what you do. I have two ATVs, I have left the batteries in them over the winter in the cold. I have taken them out and kept them in the basement. I have left a battery tender on them. So far the best result has been, to once a month charge them. I only have one charger, so charge them one at a time. I seem to get two years out of the batteries. I use the calander on my phone or desk top to remind me.

You can try connecting all lthe batteries in parallel. It will sorta work. The problem is that, if you are using a "smart" charger, once the first battery is fully charged, the charger will go into maintenance mode and slow way down. A dumb charger will keep going and charge them all. It will also overcharge them all. Better to use a multi-bay charger. I have a Genius G4 at work that seems to work pretty well. It ain't cheap, but it's probably less than 4 batteries and less than a similar Battery Tender. The cords are long enough that you could leave a couple of the batteries in the bikes.

I had a dual battery charger on my boat. I bought one that would charge three batteries but never got around to installing it. Finally sold the boat and then the charger.

So, a three bank charger that puts out about 5 amps each and charges batteries individually. Is that what you are looking for? Seems to me you could mount it and run the leads as necessary.

You don't even need 5 Amps each for little ATV batteries. 1-2 Amps is plenty.
