If I were using two, I'd hook them in parallel, and charge them both when I returned, rather than running one down, and then switching to the other battery. A battery should be charged as soon as possible when it is run down. Bad things start to happen when a battery is at a state of discharge. In parallel, the first battery does not reach such a state of discharge. By starting with one and running it down then switching, you'll soon end up with two unequal batteries.

If you want the most run time, connect them in parallel, you will get as much as 20% more run time over running one battery at the time. If you want that safety cushion and know it's time to head back to the ramp, run one at the time. When the first is run down, you will know it's best to start heading home with the other.
The heavier the load on a battery, the fewer the Amp hours they will give. A 105 amp hour battery may only give 75 amp hours of use under a heavy load (TM running on or near max). If there are two batteries in parallel, the load is cut in half so the two 105 Ah batteries will equal 210 Ah and that same load that was on one battery will provide about 180 Ah of use. That's 15 more Ah per battery than if running one at the time. Keeping the TM speed at about mid speed or lower will give you max run time.

I also got new batteries every other year.
