The LIT-22 is the ideal accessory for the Spypoint FLEX, providing extended time between camera visits and ensuring your camera stays powered longer. This 7.4V, 5.4Ah rechargeable battery easily slides into the camera once the standard battery tray is removed, offering a more efficient power solution. You can alternate between the battery tray and LIT-22 during visits or keep a pair of LIT-22 batteries on hand to power your camera year-round. Compared to standard alkaline or lithium AA batteries, the LIT-22 offers significantly superior battery life and, over time, becomes a more affordable and sustainable option for maintaining consistent power to your camera.
