I haven't even pumped these yet, but I did put caps on a couple of Trojan T-105 batteries. In my case, the batteries are next to each other. First, the tubes are cut for a larger distance between the cells. No big deal, you just need to cut about 1/2 inch off each T-105 tubing. To make the connection between each battery, attach one end of the inlet tubing, then cut as needed to make the second set connection. Now for the BIG GET YA! If you don't buy an optional RV 2000 hand pump, you're going to be in a lot of pain trying to find a 1/4-inch quick-disconnect fitting. It comes with it's own quick connector and the only way to find a soul mate is to buy a pump, I've spent a lot of time trying to find a suitable alternative. Finally, compared to standard caps, you get an overall height of about 1/ 4 inches.
