The Cool-Lux SmartPower Battery Belt and Packs use high-quality, high-reliability Lead-Calcium Electrolyte (LCE) cells and are much more forgiving. They'll hold up to poor charging habits, deep-discharge operations and can be stored with minimal maintenance. They're leakproof, recover to a full charge and they will never suffer from memory loss.
SmartPower Belts and Packs are virtually indestructible and constructed with rugged, lightweight 1,000-denier nylon. Each is precisely cut and stitched with durable, condensed, heavy-duty thread to assure a smooth, tight surface with the cells firmly encased. Soft, high-density foam padding provides comfort while shooting. This portable and easy to wear 12-volt, 12Ah battery belt has an LED power gauge to monitor voltage.
