This guy I know. . . (ahem. . ) . . . was trying to save some time removing the connector from a fully charged NiCd SCR pack . . . . so he clipped both red and black wires simultaneously . . . . with metal tipped dykes. . . . . he quickly learned what "low internal resistance" means. . . .

Remember folks, it's not the Volts that kill ya, it's the Amps. . . .

BTW - I have used the two parallel packs plugged directly (no diodes or other junk) into different channels on the receiver and it works GREAT. In addition to redundancy, the parallel packs give your servos twice the Amps to work with - especially important when using multiple digital servos.
