ICOtec C4 Power House Rechargeable Lithium Battery & Charger.
This is a must have accessory for the Outlaw and Night Stalker
The C4 Power House was designed exclusively for the ICOtec Outlaw & Night Stalker Electronic Game Callers.
*Battery consumption rate will vary based on; the volume, if constant play mode is used and if used in extremely low temperatures.
On this pack, C4 is ICOtec's product name, not a battery size. It isn't a C cell or any standard size; it's a 14.8 volt, 3700 mAh rechargeable lithium pack with its own charger, built to fit the Outlaw and Night Stalker callers.
It powers ICOtec's Outlaw and Night Stalker electronic game callers. One charge runs a call for approximately 30 to 40 hours, though high volume, constant play and cold weather shorten that. The charger comes in the box, so you can top it off between hunts.
