Clear Spot Voyager LIP-1650A Replacement Battery 3.7V 1700mAh

Clear Spot Voyager / IMW-C910W — 3.7V Li-Polymer Replacement Battery (LIP-1650A)

This is a 3.7V, 1700mAh Li-Polymer battery for the Clear Spot Voyager mobile hotspot. It fits the IMW-C910W, IFM-910CW, and IFM-930CW units. The LIP-1650A format matches the original cell dimensions at 55.50 × 47.30 × 5.10mm, so it seats flush and connects without modification.

• IMW-C910W / IFM-910CW / IFM-930CW platform: These three models share the same 3.7V battery bay, connector pinout, and BMS handshake protocol. One cell fits all three without adapter changes or firmware flags.
• Bench tested on actual hardware: We ran this cell on the IMW-C910W under a simulated five-device load with the cellular radio active. The BMS held voltage above the 3.2V cutoff threshold through full discharge cycles without triggering a false low-battery shutdown.
• Ventilation during extended hotspot sessions: Keep the unit on a hard, open surface when streaming for long periods. The cellular radio runs at peak output power when connected devices are far away, and trapped heat accelerates cell degradation faster than normal charge cycling does.

Hotspot disconnecting users mid-session on a new battery

The Spot Voyager draws power from two radios simultaneously — the cellular modem and the 2.4GHz WiFi chip. At maximum client connections, combined current draw spikes sharply. If the cell's internal resistance is even slightly elevated, voltage sags below the modem's operating floor and the unit drops the session to protect itself. A new LIP-1650A cell with low internal resistance keeps voltage stable through those draw spikes. Check that the battery contacts are clean and fully seated, as a partial connection raises effective resistance at the source.

Spot Voyager won't power on after sitting unused

Li-Polymer cells self-discharge at roughly 2–3% per month at room temperature. After several months in storage, the Voyager's battery can drop below the 3.0V minimum boot threshold the BMS requires to release current to the board. The device shows nothing on power-on — no LED, no startup screen. Connect the unit to a USB charger and leave it for 20–30 minutes before attempting to power on; the BMS needs to confirm cell voltage is above 3.0V before it will allow the startup sequence to proceed.
