On lead acid batteries when they are discharged below 11 volts too many times they lose capacity. It happened to me before, even the high performance agm's can only handle a couple of discharges to 0 percent and they lose capacity.
When you charge them they are able to reach 14.4 volts quickly but won't last long when you put a load on them.
The goal zero 500 should work good for you, the newer goal zeros are suppose to able to take more amps during charging to charge more quickly. They are solid performers just a little expensive. The 500 model should be a 50ah unit which is comparable to a 100ah lead acid. And the goal zeros you can take them down to 0 percent (about 9 volts with a 3s li-ion lithium) with no problem at least 300 cycles, if you discharge halfway they will last even longer. Unlike lead acid, you can charge them at your convenience.
