My Lance has (2) 100w panels and a 30a controller. It has a single battery compartment and after sitting covered since fall, the battery is dead of course after I pulled out t out to get ready for summer. I'm either going to replace with a single AGM or some tell me to go with two 6v golf cart batts? I have 2 AGM's in my travel trailer with 400w on the roof and it does great but the Lance is more compact with one battery compartment. So two 6v or 1 AGM?

So the 'single' battery compartment will hold 2 batteries? I would not choose to go flooded battery over AGM. Agm's are just too nice and maintenance free.

Have you determined your daily energy use? Get batts of at least four times your daily use. Generally 200 solar watts can recharge a 200 amp battery bank. I use 50 to 65 amps per day and have 300 solar watts recharging T125s at 240. Usually full by noon. Works great.

Remember that AGM's can be laid on their side, or at an angle with zero adverse effect. You can also remove the slide tray to create more room or add a torqlift hidden power battery box on the truck frame under the bed. I was able to stuff two group 31 AGM's into my Lance 1055 to go along with my 200 watts of solar

Battery box on the Lance is a single. Pretty much answered my own question. I'll go with a large AGM for now. Maybe add another to a storage area later if needed. I've got a Honda 2000 to make it work as needed.

What's the best battery setup for 200w solar? | Good Sam Community

Best performance? Lithium, AGM, True deep cycle such as GC2 or scrubber, everything else. (in that order)

Price? Just reverse the list.

This is the most concise answer yet!!

I think that's a good call.

Does cost factor in?

If you need to lay the battery on it's side, AGM makes a lot of sense but they are expensive if you aren't worried about them being laid on their side.

Lithium is good if you need to cut weight but they are even more expensive than AGM and require some special care.

The best battery setup is AGMs of the largest size that will fit in the battery compartment

If you only have room for 1 large battery, go with the largest Lifeline AGM battery that fits.
