Share: What's Your Battery Pack?

Since the Flex list of Maestro battery packs is short and contains some that no longer are available, I thought we should build a current community list of what people are using in their Maestro, and if they are still available for ordering.

If you are willing to share with the community, please post a reply as follows:

1.  Battery pack model and capacity in mAh:  
2.  Link (URL) for ordering:
3.  Fits inside Maestro (Yes/No):
4.  Auto Starting (no button push needed to turn it on)?:
5.  Run time in hours that you are getting on your Maestro:

This should result in a more usable list for people purchasing a Maestro (like me), since
the advertised capacity is often "alternative fact" in this market :-)

Thanks for sharing.
Cheers,

Neal

    Polanfo Mobile Power Model Q5 (12000mAh) is one of my batteries (no longer available?).  However for 3x the price ($59) they sell their newest and best version, the M20000 Power Bank Ultra Slim External Battery for $59.  Here is a link on Amazon

    https://www.amazon.com/External-Battery-Portable-Charger-More%EF%BC%88Black/dp/B01641KC3I/ref=sr_1_2...


    I also have a GETIHU Power Bank Model PB-02 (13000mAh) which is .15" too wide (3.00" is max width) but I can still hold it in place with the Velcro straps (I cannot put on the battery door) .  It works fine and is less money ($19.99)

    Neal,

    After reviewing the batteries available that seemed to fit inside the Maestro and the associated run time, I took a different approach. I focused on finding an external battery that could plug into the Maestro power connector. I want to use the Ethernet cable connection which is not available using an internal battery (Wi-Fi only).

    1. MAXOAK 50000mAh 5/12/20v Portable External Battery Bank

    2. https://www.amazon.com/s/ref=nb_sb_ss_i_1_6/136-1384624-9689657?url=search-alias%3Daps&field-key...
    3.Does NOT fit inside Maestro=no
    4. NOT Auto starting (has power button)
    5. Run time with Maestro using 1G Ethernet connection 10+ hours
    6. Size = 8.1" x 5.3" x 1.3"
    7. Weight = 2.77 lbs

    The battery has a 12v output and the supplied cable plugs directly into the maestro with no adapters.

    Best Regards,

    Brian/W8WD

    I was lucky enough to find the Polanfo 2000M packs on Amazon back when we were alpha testing the Maestro. I ordered two and reported my findings to Flex and it went on the list of "recommended" packs. Unfortunately it is no longer carried on Amazon or anywhere else I can find.

    Like David, I also have two of the Polanfo 2000M, but just recently purchased two of the Quslly  20000mAh batteries here:  https://www.amazon.com/gp/product/B0792Y6XTP/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1  They fit in the Maestro, auto start, do not know run time.  I use some of these for other purposes-take them to the beach incase the phone or Bluetooth speaker batteries die.  I am going to take the Maestro to the beach tomorrow for field day.

    Nice find, and a nice price.

    I bookmarked the link.

    I can not take the credit for this as someone posted that battery find a few weeks ago.

    Yes, David this is a good find.  I ordered a blue one, it arrives Sunday.  With a 20000mAh rating it should last even longer than my other batteries.

    So I know the Maestro likes 2.5A so the 2.1A from this battery pack isn't an issue?

    Guys Do a run time test when you get that battery. Many vendors lie about specs, and that battery is not twice as large as the 10,000 mah.

    I purchased 16 18650 Lithium Ion batteries and paralleled 4 sets of 4 batteries in series.  Fully charged it is 3.7 volts X 4 batteries = 14.8 volts which is under the 15 volt spec.  Paralleling four packs of four gives me 12 amp hours which lasts a very long time (haven't ever run it long enough to deplete it).

    The whole thing fits in a small travel pouch dimensions 4.5" X 7.5" X 2.5".

    Mike:   I can't see clearly if you are using BMS (Battery Management System) boards in there to keep your cells balanced.   Very important for maintaining cell balance to avoid eventual fire.
