true voltage of nicad cells is 1.25 volts which gives 3.75 volts,these days everyone is calling nicads nominal voltage of 1.2 volts.that is why on a fully charged pack you see voltages over 5 volts.
So you're saying it's OK to fly with only 0.15 volts above cutoff? Think about the possible meter errors before answering that one.
