This was post 18,659 from March 25, 2024.
I have some other posts before and after page 1253 on 3/25/24 that pertains to the battery.
———————
Be sure to get this specific battery (KBT) from Amazon, it has the correct battery management and voltage and works in the Poly.
I bought a 4 pack of this KBT battery for $36.99 and can confirm that my Poly is working since March 25.
I even upgraded my Mojo to a Mojo2.
A single KBT battery is $12.99. The batteries are available with Amazon Prime - free one day shipping.
The only issue is that the battery percentage never gets to 100 % after a full charge - it usually stops at 80 %.
I have a two hour commute and the Poly battery drops about 5-6 % per hour.

My primary use is the SD card and Rigelian, which is $3.49 per year. Rigelian works great and has the ability to read the cover art using a filename that you can choose.
I use Hotspot Mode (no gateway) with a iPhone 14 Pro Max running iOS 17.4.1.
I can listen to music and use the iPhone browser at the same time.
1. Turn on Poly
2. Use GoFigure to enable Hotspot mode. (It takes 30-60 second for your 2.4 GHz network to become available).
3. Connect to Poly’s WiFi on iPhone.
iOS WiFi settings for internet browsing with Poly. SSID will be Poly-#########
a. Auto Join on
b. Auto Login off
c. Enable low data mode
d. Disable Private WiFi Address
e. Disable “Limit IP Address Tracking”
f. Configure IP - Manual
— IP address - 192.168.1.111
— Subnet Mask - 255.255.255.0
— Router (Gateway) - Leave Blank
g. Configure DNS Manual - 8.8.8.8, 8.8.4.4
h. Configure Proxy - Off
4. Open Rigelian.
Once my commute is completed - I use GoFigure to disable HotSpot mode.
After disabling the Poly’s Hotspot you can also place the Poly into Airplane/Bluetooth mode to further save the battery.
I usually charge my MojoPoly when not in use - the Mojo2 will illuminate purple when it’s fully charged.
These are my Poly battery replacement notes - use at your own risk.

Start - 25 March 2024
Cut old battery wire right at the base to save the connector and as much wire as possible. You will splice the old connector onto the new battery.
Take out SD card.
Poly has four screws on back - the Poly case slides up and out on a slight angle -
the Bluetooth cover has a ridge on it, be careful not to damage.
Poly - opened.
Do not remove the two screws that hold in the PCB board - the optic bar will fall out and it’s a PITA to get back in place.
Note the white battery connector - use a spudger tool to gently pry from board -
it lifts up from the side opposite the wires. It will snap back in place.
Splice the new battery into the old connector.
The original battery is held in place with double sided tape, you will be able to remove it and re-use the tape on your replacement battery.
Both the new and original battery will read between 3.7 V and 3.9 V on a multimeter. If the replacement battery is 4 V or higher, do not use.
I used tape instead of solder as I expect to do this again and there isn’t much of the original connector’s wire to spare.
To re-assemble - the optic bar lines up with the bottom hole on the Bluetooth window.
Carefully slide the Poly back into place
- the back has a thread that lines up with case. Also ensure that the Bluetooth window’s ridge is lined up correctly.
Final working system - 3/25/24.
Fully charged Mojo2Poly - 5/6/2024.
Mojo2Poly in Desktop mode - 5/6/24.
