GoPro Wi-Fi Remote YD362937P Replacement Battery 3.7V 350mAh

GoPro Wi-Fi Remote — 3.7V Li-Polymer Replacement Battery (YD362937P)

This 3.7V, 350mAh lithium-polymer battery replaces the OEM cell inside the GoPro Wi-Fi Remote (ARMTE-001). It fits the remote used with HERO3 and HERO4 series cameras to trigger recording and control playback wirelessly. Swap it when the remote stops holding charge or powers off unexpectedly during a shoot.

• ARMTE-001 and HERO3/HERO4 remote compatibility: These remotes share the same battery bay, connector polarity, and 3.7V cell spec across the Wi-Fi Remote lineup. One part number covers all of them because the power circuit and physical footprint are identical.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the ARMTE-001 remote. The protection circuit triggered correctly at low-voltage cutoff, and the remote paired and responded to camera commands throughout testing.
• Connector orientation on reinstall: The flex connector on this remote sits flush against the PCB with a locking tab. Press it straight down until it clicks — angling it sideways cracks the connector housing and causes intermittent power loss that looks like a dead battery.

Why the Wi-Fi Remote loses pairing range before the battery looks dead

The remote's wireless transmitter needs a stable voltage rail to push a clean signal. As the lithium-polymer cell ages, internal resistance rises and voltage sags under the transmitter's draw — even if the remote still powers on. Below roughly 3.5V under load, the signal becomes weak enough that the camera drops commands at distances that previously worked fine. Replacing the cell restores the voltage headroom the transmitter needs to operate at full output.

Remote shows solid LED on charge but reads flat immediately after

This happens when the cell has dropped below the battery management circuit's recovery threshold — typically under 2.5V — due to sitting discharged for an extended period. The charger sees the LED trigger voltage but the cell can't hold energy once disconnected. Some cells recover with a slow trickle charge held at 2.8–3.0V for 20–30 minutes before a full charge cycle is attempted. If the cell returns to flat within seconds of removing from the charger, the cell is unrecoverable and must be replaced.
