Yes, you can purchase an optional battery pack on our site to power the BlumSafe’s winders with 4 “D” cell batteries (not included). This battery pack with alkaline batteries will last approximately 4 months for a three winder installation before the batteries need to be changed (longer with lithium batteries). Accordingly, we strongly urge that you not use the battery pack option with more than three winders operating at any one time. Please consider the possibility that in the future you may add more winders to your BlumSafe -- most customers who start with fewer than 12 winder in their BlumSafe add more winders later -- and sometimes an additional BlumSafe, so plan ahead!
