    I'd first measure the battery voltage. I don't have your charger, so I don't know if it has a monitor function.
    A battery checker or one of the pocket DVMs should suffice.

    Actually that's not quite true. The chemical "mix" can vary, such that a lipo mild mix might result in 4.1v or so, and a "hot mix" around 4.35v.

    It's possible that the servos are generating very short term spikes that are tripping the voltage checker.
    You may be able to add capacitors to the servo leads, which should help reduce the spikes.
