Vicar,

That's a good question, but they don't make a combination unit.

To answer your question about spotting problems: That's what the tester is for. From time to time you will do a spot check on your flight batteries to see how they look. On a transmitter battery it is pretty easy to tell when you have a problem as the voltage will read low after charging. On my Futabas, the voltage reads around 11v after charging and will stay near that until I start to use it. I recently had a transmitter battery that only read 9v after charging. I put it on the tester and it showed that the capacity was only at 200 ma (should have been 500). I cycled it a few times and got it back up to 500 +.

Hope this answers your question.
