Extend the battery life of the SPYPOINT FLEX with the LIT-22 rechargeable lithium battery. Simply remove the FLEX battery tray, and install the LIT-22 instead to extend the time between camera visits. For use with the SPYPOINT FLEX only. THE LIT-22 is the perfect accessory for the SPYPOINT FLEX if you want to get even more time between camera visits. The 7.4V, 5.4Ah battery slides in easily once the standard battery tray has been removed. 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.
