Maestro rechargeable battery packs

Mark Griffin
Mark Griffin Member ✭✭

I am considering a Flexradio Maestro. I realize you can power it by A/C. But I also know that you can install a battery pack in the back of the unit. Does anyone have any recommendations on a battery pack that will fit in the Maestro? Not sure if it can be charged while in the Maestro or not. But I don't have any problems with taking it out of the unit to charge it.

    Also Flex recommends charging the pack out of the Maestro. This is for safety reasons.

    Not all battery packs are created equal with charging requirements and is one reason no internal charging was available. Also as I mentioned, safety. Think hoverboards and the fires started by charging those.

    and last, when charging LiPo battery packs, do not leave them unattended just a precaution

    Has anyone ever heard of a Maestro fire? :)

    I normally operate via ext 12v supply and only install my mogix when full portability is required. It's about battery management more than safety.

    It would be nice if Maestro had "full service" battery support. (Internal charger & battery charge indicator, switchable mains/battery operation, etc.) Some day...

    All LiPO can catch fire, one thing to watch with the Maestro is that when the Battery begins to swell it will push on the back of the screen and cause black spots on the screen.

    New Maestros have not been available from Flex for roughly a year. Did you locate a used one? “A” or “B” model?

    I am thinking about ordering a new one. Online it says 4th quarter 2022. I assume there in a long waiting list.

    I suggest waiting until you receive the updated Maestro from Flex before buying a battery. It may have different requirements.

    I just placed my order. Time to just wait and see how long it will take.
