  • Micro & Mini Air Pump Voltage Requirement clarification.

    Bob, Dave, Ghost of Rickover, whomever....

    A tad confused regarding the voltage requirements on both the Micro & Mini air pumps....

    Understand it's all about range, but I still don't want to "cook" anything.

    Starting with the Micro...
    • Rated Voltage DC 6V
    I take it it will run fine with a fully charged 2CS (8.4V eventually dropping to 6V) without a voltage drop diode?
    I thought I saw a resistor on one unit I had.

    The Mini...

    Online you state:
    • Rated Voltage DC3-7.2V
    The label in the photo list's 12V. I'm taking it will be fine in a 12V system (Nom 12.6V underway)

    Eddie wants to build!

    The small one will be happy all day at 8-volts or lower. Those used with 11.1-volt systems have a voltage dropping resister (not a diode). Those pumps used in SD's intended to employ 7.4-volt are used neat.

    The big ones are fine for 11.1-volt systems.

    No problem, Ed. Measure twice, cut once.
