Yup - been using that before we knew they would destroy the early ignitions due to over-voltage (not)

Right now, it's hard to beat a straight LiFe setup, providing servos are up to the 6.6v. Believe it or not, some not-so-name-brand but high quality servos really HATE 6.6 v. That was interesting to learn...
