IceCap Battery Backup v3.0 for Aquarium Pumps

When it comes to a power failure, it™s not a matter of if, but when. Fish and corals can perish in as little as 4 hours without water flow. The IceCap Battery Battery Backup Version 3.0 will keep your flow pump running uninterrupted in the event of a power loss for ~35 hours*. You can connect two pumps to the battery backup and run them simultaneously for ~17 hours after the power goes out. To double your backup run time, you can even connect two battery backups together for further protection.
