GoPro Remote ARMTE-001 battery Replacement

GoPro Hero3/Hero4 family WiFi remote control

Tools needed. Small hex screwdriver, 1.5mm Hex driver, spudgers, soldering iron and solder

Remove the back case from the ARMTE-001 using the 1.5mm Hex driver.

REMEMBER THAT BATTERIES CAN CATCH FIRE IF NOT PROPERLY HANDLED. BE GENTLE when prying up the old battery. DO NOT PIERCE IT.

Using a spudger carefully pry either side of the battery from the circuitboard, until it comes off.

BE CAREFUL NOT TO PIERCE the old battery (I know I’m saying it again!)

Once the battery is off, there are three small screws holding the circuit board in place. Top left, Top right and bottom right in the first photo.

Remove the three screws, then with a spudger gently pry up the circuit board from the hole where the cables go in.

At the bottom left there is a small plastic clip you have to lift the board away from this.

Underneath the board, is a ribbon cable to the display. Don't disturb this, you don't need to disconnect it as the board will swing up and out. See the last photo.

Unsolder the three connections. Noting which colour wire goes to which pin.

The replacement battery will have a small cover over the red (+) terminal.

Solder the black (-) connection first, then the white/yellow, then remove the cover from the red (+) cable being careful not to short it anywhere on the board and solder it last. Check your connections.

Now it is time to re-assemble.

Slide the board back into the case, being careful not to damage the ribbon cable to the display. There is a plastic clip at the bottom left of the first picture, you must ensure the board goes under this, then the board will lie flat in the case.

Replace the three screws

Check the board is level in the case, and that it is not resting on the plastic clip at the bottom left.

Place the battery on the top, and check the cover fits without the seal in place. You can tuck the wires alongside the battery.

Using a small piece of flat double sided tape stick the battery to the board. I placed the battery as far as I could to the top of the case, and to the right of the white line on the left by the QR code

NOTE that the battery MUST NOT cross the white line beside the QR code or the case will not close.

Replace the seal into the case. It only fits one way around as the cutouts are different sizes, be careful to ensure it is level, not twisted and even.

Replace the cover carefully, checking it is even and not resting on anything

Finally with the 1.5mm hex driver, replace the screws. Tighten then top left then bottom right, the top right and finally bottom left. Don't overtighten.
