This is the ratings of a single GP27 battery. So take it as you will. Two T105s like everyone try to tout as the best will have what once you have them hooked to give you the required 12VDC? Compared to two 12VDC batteries at the above rating. Comparing the cost, again, the T105s 30 dollars for what ammounts to one 12 volt battery, vs about 225 dollars for two 12 volt batteries.
It always come down to homework. Now if the OP were installing 4 golf cart batteries and did a fair ammount of boondocking I would be first in line to say go for it. But he is installing two golf carts, and that simply does not make sense dollar wise.
