Elvie Stride Disassembly

Introduction

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

To reassemble your device, follow these instructions in reverse order.

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?

Gregory Fung - Réponse

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
