Foxpro Banshee 11.1V 5200mAh Replacement Battery

Foxpro Banshee / CS24 Series — 11.1V Li-ion Replacement Battery (LITH/CHG,PN34318)

This is an 11.1V, 5200mAh Li-ion battery for the Foxpro Banshee and CS24 series electronic predator callers. It slots into the battery compartment and powers the onboard speaker and sound playback system. Confirmed fit includes the Banshee, CS24, CS24B, and CS24C, plus additional CS-series models sharing the same form factor.

• CS24-series platform fit: The Banshee, CS24, CS24B, and CS24C all run the same 11.1V three-cell Li-ion pack with a matched connector and BMS handshake. A voltage mismatch here causes the caller to refuse power-on entirely, so cell count and nominal voltage must match exactly — this pack does.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the Banshee platform. The BMS held cell balance across all three cells, and the protection circuit tripped cleanly at the low-voltage threshold without locking out the device on reconnect.
• Pre-hunt warm-up routine: Li-ion cells lose 15–25% capacity at 0°C and up to 40% at −20°C. Keep this battery in an inner jacket pocket on the walk to your stand and install it just before calling. A cold battery pulled straight from a truck cab in January will underdeliver from the first cycle.

Why the Banshee shuts down mid-session in cold weather

At sub-zero temperatures, internal cell resistance rises sharply. The BMS reads the resulting voltage sag as a low-battery condition and trips the protection circuit — even if the pack still holds a usable charge at room temperature. This is not a fault with the battery or the caller. Warming the pack to above 10°C before use keeps cell resistance low enough that the BMS stays out of the way through a full calling session.

Caller won't power on after sitting in cold storage all off-season

Li-ion cells self-discharge slowly over months. If the pack drops below roughly 9V total — around 3V per cell — the Banshee's BMS may refuse to boot the device as a deep-discharge protection measure. Put the battery on charge immediately; most chargers apply a low-current recovery current at this voltage before switching to full charge. If the charger shows a fault light and won't engage, the pack has fallen below the recovery threshold, typically under 2.5V per cell, and will need replacement.
