The first charger I bought was the Triton2. I used the 7Ah battery in the battery box for a year to charge my Rx - Tx in the field, run my fule pump. I Then put the 7Ah battery on the Wal-Wart over night. This worked , like I said for a year. One day, at home, I cycled my Rx battery with my Triton2 . My 7Ah battery discharged in about 3 hours, couldn't complete the cycle.

I bought a AC to 12V power supply and now all is good. I have seen some flyers use Motorcycle batteries in the field. One way or another you will need a 12V power source in the field. The auto/truck connection is a little clunky for me, so I still have the 7Ah battrey box as my source in the field.

I have all 1100Mah batteries in my Receivers because they came with the transmitters, but I think a 1500Mah receiver battery would be an improvement and save a field charge or two.
