Stealth Cam FieldMax Features The Stealth Cam FieldMax Lithium Rechargeable Battery Cartridge is built around a 12-volt 5 000 mAh lithium-ion cell giving compatible cellular trail cameras extended runtime without constantly swapping batteries. It is designed to work with Stealth Cam s Flashback Deceptor MAX and Fusion MAX cellular trail cameras serving as an alternative rechargeable internal power supply. This power source keeps cameras running longer in heavily wooded areas where sunlight is scarce and solar charging options are limited. Easily withstanding extreme temperature swings and adverse weather conditions the cartridge is built for year-round deployment in the field. Each cartridge recharges through the included USB charging cable eliminating the recurring cost and hassle of disposable AA batteries and reducing the number of trips needed to service a camera. This listing includes a 2-pack giving hunters a spare cartridge to swap in while the other charges keeping a camera running with minimal downtime. The rechargeable design is especially useful for cameras placed in remote or hard-to-reach locations where frequent visits are impractical. For trail camera owners who want fewer battery changes and more consistent power in the field the Stealth Cam FieldMax Battery Cartridge is a practical upgrade.
