Battery Backup Accessory
The VorTech Battery Backup will power one pump for up to 30 hours or two pumps for 15 hours each. Alternatively, multiple battery backups can plugged in to each other to provide even more run time during a power outage. There is no other product that detects an outage and provides as much insurance for so little money.
