There are a couple of chargers that have more features than the TritionII and Triton.

For example, any one that comes complete to work from DC and AC like that one you mention.

You ought to take a look at the Accu-Cycle Elite while you're looking at chargers. It will do two different batteries at once. And the readout screen shows them both. And it'll work all those batteries in your list (most today will). And it's only $20 more from Tower than the one you mention.

When I come home from flying, I plug my TX AND the airplane into the Accu-Cycle Elite and go to supper. After supper, both are at full charge and are on trickle charge. I can leave 'em or not. The readouts for the two batteries give me an excellent check of how those 2 batteries are doing. I remember how much I used the TX and how long I flew the plane and right away have an idea of how things are working inside those batteries. I've found two RX batteries in the last year that were in need of help. One was trashed, the other responded to cycling a couple of times. It still was put into a less expensive airplane.

It's not hard to find better chargers.
