The 6EX manual recommends landing as soon as possible if the voltage is below 8.9 Volts and land immediately if below 8.5 Volts.

A 3S Lipo is possible in the 6ex and many people use them successfully however there is a risk that too high voltage from a fully charged 3S battery (12.6 Volts) may damage the radio.
