SIGMA NIPACK NIMH FLAT BATTERY

This battery from Sigma Sport prolongs the burn time of the average light set.  It weighs in at only 350 g and has a universal fastening system so it'll fit just about anywhere.  Its high energy output raises the burn time of the Mirage EVO to 4 hours, Vario to 10 hours, and the SILED to a whopping 140 hours.  It requires an additional Nipack charger because this battery will not work with Lead Acid battery chargers.  The automatic quick-charge unit has a charge indicator and has overcharge protection, temperature protection, and a current regulator.
