rocomendations for radio Dx2.0 lipo

[BrianG]

Any 3s lipo that will physically fit in the tray will work. The DX2.0 uses 8 AA batts, which have a voltage range between ~8.8v (1.1v/cell) up to 12v (1.5v/cell). 3s lipo is good from 9v (3.0v/cell) up to 12.6v (4.2v/cell) fresh off the charger. That extra 0.5v won't hurt it, but if you are worried, you can set your CC/CV threshold lower providing your charger supports it.

In any case, just watch the voltage meter on the radio to prevent discharging too low, and/or get an LVA (low voltage alarm).
