Ionic GenBox 1.3B Expansion

About the Product Extend Your Backup Power The GenBox 1.3B expansion battery module extends your GenBox 1200S runtime from approximately 6 hours to 12, 18, or 24 hours. Stack up to 3 modules for multi-day backup power without generator recharging. Why Add Expansion Modules? You experience outages longer than 6 hours One module doubles your runtime to approximately 12 hours—enough to ride out most storm-related outages overnight. You need multi-day protection With 2-3 modules, you have 18-24 hours of continuous runtime—nearly a full day of refrigerator protection without recharging. You’re powering critical medical equipment Extended runtime provides peace of mind for medical devices that cannot tolerate interruption. You want to minimize generator runtime Run longer on battery between recharging sessions—potentially only needing your generator once every 1-2 days. How It Works All modules function as one unified system: Batteries charge and discharge together automatically Base unit manages all charging and protection LCD display shows total system capacity System auto-recognizes new modules when added Installation: Stack module, install side brackets, connect parallel port, power on. Takes 5-10 minutes per module.
