Extend the battery life of your Spypoint FLEX cellular trail camera with the LIT-22 Rechargeable Lithium Battery Pack. Offered here in a 2-pack, the LIT-22 eliminates the need to replace disposable alkaline batteries. The 7.4V, 5.4Ah battery easily slides in once the standard battery tray has been removed. You can alternate between the battery tray and LIT-22 on visits, or get a pair of LIT-22s and keep the camera powered with a rechargeable option year-round.
