My wife's Elvie Stride got some milk inside and suddenly stopped working. I was able to take it apart and disconnected the battery. After cleaning the milk off and letting everything dry, it charged properly and started working again.
This isn't a proper disassembly guide, but hopefully it gives you the courage to pop yours apart if it stops working!
-
-
Take off the rubber sleeve around the case.
-
The two halves of the clamshell are held together by about 9 plastic snaps - no screws or glue.
-
A handful of guitar picks and gentle prying on each side should be sufficient to pop it open.
-
-
-
Four T6 Torx screws hold a black piece of plastic into the front clamshell.
-
-
-
-
The battery is held in place by a small bit of adhesive. A spudger and light force is sufficient to remove it.
-
-
-
The PCB is held into the black plastic bracket with three T6 Torx screws. Remove these, and the device is almost completely disassembled!
-
The battery connector pops vertically out of the socket (not by sliding parallel to the PCB).

We can identify a few key components on the board:
-
Nordic Semi nRF52832 (Bluetooth chip)
-
Winbond 25Q32JV 32MB SPI Flash
-
TI BQ25601 battery charge controller
-
WCH WC340H USB-UART controller

my battery keeps disconnecting inside the hub, not sure how to fix it but that could be a common issue with them.
I didn't have a guitar pick on hand but was able to use an old gift card to open this up. Any credit card would work here.
what battery is used? is it a common size one can buy easily, with a standard connector?
It's a standard 18500 li-ion cell, nominally 2300mAh. I can't identify the connector but it looks similar to a Molex Pico-EZmate.
The connector is shrink-wrapped onto the battery, and could probably be removed and taped onto a new one.
The battery connector definitely comes away too easily from the board. If my wife's does it again, I'm thinking I'll see about using a dab of hot glue to see it down. It could damage it but only one way to find out. @angeladarby
Good luck
