I am under the impression 6V golf cart batteries will tolerate more of a discharge before sustaining damage, or am I smoking bad weed ?
Remember the panel does not care a wit what you have.
Only what the VOLTAGE is.

50% of capacity is still the limit before recharging.
Below that you will damage space ship batteries.
How far below will determine how much damage you do.

With those 6 Volt golf cart batteries in series, it will just take longer to get to 50% capacity.

You're not smoking bad weed. The term deep cycle is a little confusing. The "deep" part of deep cycle is better understood in comparison with a starting battery. A starting battery, like in your car, provides a lot of current for a very short period (seconds) and may never get below 10-20% discharged until the alternator begins to recharge it. It can do this thousands of times.

Deep cycle batteries provide a steady and relatively low current but over a much longer period before needing t be charged. They can do this hundreds of times. Discharges deeper than 10-20% are the norm, but we still cannot go too low too often or we shorten the life of the battery.

Keep to 50% and above and the batteries will give you years of service

Exactly. My T145 batteries have 260ah, which will give me 4-5 days dry camping until we are at 50% without us being too stingy. This is good, I think.

Gentlemen, thank you.

I now 'get' the deep in deep cycle.

I have 220AH now, thanks to a pair of Costco GC2 - $80 each. Very happy.

Reviews I found were pretty good and the price was right.

I'll baby them as much as I can and report back on performances.

Regards,
