About this replacement
Stealth Cam Deceptor Max / FieldMax Series — 11.1V Li-ion Replacement Battery (STC-RLCMAX)
This is an 11.1V 3400mAh Li-ion battery for Stealth Cam trail cameras including the Deceptor Max, FieldMax, Flashback, and Fusion Max. It replaces OEM part STC-RLCMAX directly. Use it in remote field locations where the original pack has drained during extended wildlife monitoring sessions.
- Multi-model fit across the Deceptor and FieldMax platform: The Deceptor Max, FieldMax, Flashback, and Fusion Max all run the same 11.1V three-cell architecture with a shared connector and BMS handshake — that is why one pack covers this group of cameras.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the STC-RLCMAX platform. The BMS responded correctly to cell voltage thresholds, and the camera recognised the pack without firmware prompts.
- Cold-field pre-warm tip: Li-ion cells lose 15–25% capacity at 0°C and up to 40% at –20°C. Before heading to the stand in freezing temperatures, keep this battery in an inner jacket pocket. Swap it into the camera just before mounting — a cold battery left inside an unheated housing overnight will start the day significantly under capacity.
Why the Deceptor Max misses triggers after a cold night in the field
The Deceptor Max draws a short burst of power each time its PIR sensor fires and the image processor spins up. In cold conditions, internal cell resistance rises, and that burst causes a sharper voltage sag than the same draw at room temperature. If the sag drops close to the BMS low-voltage cutoff, the camera may stall mid-trigger or skip captures entirely — without showing a low-battery indicator. The fix is starting the day with a warm, fully charged pack and swapping batteries before the temperature drops below –10°C.
Camera shows full charge then shuts off after a few captures
This is classic shallow-cycle capacity fade on a Li-ion pack that has been repeatedly topped off without full discharge cycles. The fuel gauge reads the surface charge on the cells, not true capacity — so the indicator lies. The BMS then hits its real low-voltage floor within a handful of trigger events and cuts power. Condition the new pack with two full charge-and-discharge cycles before field deployment, and check resting cell voltage sits above 11.0V before mounting the camera.
