Hi guys., Just wanted to announce the battery extenders for BOTH the IR Hunter MKII's and IR Patrol are now available through TNVC. They are $74.95 and will be on the web site in a few days. If you would like to order, simply email sales at tnvc dot com and we'll get you fixed up.
The chart below represents the new IR Patrol battery consumption test results for both single and with the extension. The specific battery used for testing was the Energizer Lithium CR123's. As I mentioned before, since we are about to release our new TNVC Mini-DVR, Rifle/Helmet pouch, cables, and wanted to incorporate a external battery pack...IR Defense has informed us they will not support or warranty units that may be damaged by using any external battery packs etc. for use on both the IR Hunters and IR Patrol systems. With that said, the use of the battery extender is currently the only way to increase battery life without voiding any warranties.
