Stealth Cam Revolver EM10 Replacement Battery 11.1V 6500mAh

Stealth Cam Revolver Series — 11.1V Li-ion Replacement Battery (EM10)

This is an 11.1V 6500mAh (72.15Wh) Li-ion replacement battery for the Stealth Cam Revolver trail camera lineup. It fits the Revolver, Revolver 360, Revolver 36MP 360, Revolver Pro, and related models. It replaces OEM part number EM10 directly.

• Revolver series compatibility: All Revolver variants listed share the same 11.1V three-cell Li-ion architecture and EM10 connector interface. The BMS handshake is consistent across this platform, so one cell pack covers the full range without modification.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge on a Revolver unit and confirmed the BMS balances all three cells cleanly at cutoff. The protection circuit trips correctly on over-discharge before the camera firmware logs a low-battery shutdown.
• Cold-deployment charging practice: The Revolver is often left in the field through temperature swings. Never charge this pack when the cell temperature is below 5°C — Li-ion cells that accept charge below freezing suffer permanent plating damage inside the anode that reduces capacity with every cold-charge cycle.

Why the Revolver logs fewer images per charge in winter

Li-ion cell chemistry slows ion movement as temperature drops. At 0°C a 6500mAh pack may deliver closer to 5000mAh of usable capacity. At -20°C that loss can reach 40%. The Revolver's PIR sensor and motor-driven lens rotation both draw current spikes that the weakened cold cell handles less efficiently. Store the spare pack in an inner jacket pocket and swap it into the camera just before deployment to preserve as much charge as possible.

Camera shows full charge on install but shuts down minutes later

This happens when a pack has sat unused for months and individual cells have drifted to unequal voltages — one cell may already be near or below 2.5V while the others read higher. The camera's firmware reads the string voltage as acceptable on power-up, but the BMS trips on the weakest cell almost immediately. Connect the battery to a charger and let it complete a full balance charge cycle until the indicator confirms all cells are topped. If the charger does not terminate cleanly within two hours, check that the charger output is rated for 12.6V at end-of-charge for a three-cell 11.1V pack.
