In light of IFMAR and other organizations allowing high voltage (3.8v 1s/7.6v 2s nominal) lipo batteries with the stipulation that the current charge termination voltage remain the same (4.20v 1s/8.40v 2s maximum), ROAR will follow suit allowing HV lipos at 3.8v nominal per cell starting January 1, 2017.
Cells with a nominal voltage of 3.8V may be used as from 2017 provided that a majority of manufacturers has them available). The maximum charging cut-off voltage remains at 4.20V. per cell
