Is there a such thing as a voltage regulator for LiFe batteries?
Short answer (not reasons why you don't need one) is yes.
Had the situation where I forgot to take my two 4 cell NiMh battery packs to a jet fly-in.
The closest batteries available from trade vendors at the meet was 2 cell LiFe batteries & a friend bought
two for his helicopter which he lent me for the weekend.
Some of the older servos in my jet weren't happy with the higher voltage of the LiFe batteries so I bought two
Powerbox Digiswitches which have selectable battery types in the menu including LiFe.
Regulated output is 5.9 volts.
