What are +/- of replacing original 12V Interstates?

IMO, there are pluses to either, and no minuses.

Only variable is ahr capacity. Which will better meet your needs?. Plus to AGM is no maintenance.

[dznf0g]

There are some other physical factors. Available physical dimensions vs. Space constraints. Inside vs. Outside placements. Maximizing Ah capacity, given those considerations. Necessary charger/controller changes?

Because the 6 volt (golf cart) batteries are taller you can get more amp hours in a smaller footprint.

Both are notable battery types that would be a great upgrade. Both a highly durable, long life, deeper discharge capabilities over standard batts.

AGM
Pros
- no need to water
- higher charge and discharge rates (to run higher wattage inverters)
Cons
- cost
- if abused or accidentally damaged with deep discharge in storage, cost to replace

6V FLA
Pros
- Cost
- Easy to source
Cons
- Have to water couple times a year

[dznf0g]

Weight vs. Ah capacity gives AGMs a nod over flooded.....if that is a concern.

Thanks all for your responses. If I go with 6V, I'll need to modify the battery box, right?

Vinnie's North Bay used to have a drop in adapter to expand the battery box. You might want to check with him.

First of all If you are considering 6V batteries (more amp hrs.) I can highly recommend Lifeline AGM deep cycle batteries. Mine have been in service since 2013 and still strong.
