The IceCap Battery Backup v3.0 keeps a flow pump running during a power outage — fish and corals can start dying in as little as 4 hours without water movement, and this switches on immediately when power drops to bridge that gap. Voltage: 12V, compatible with most 12-24V pumps (Maxspect, IceCap, Reef Octopus, and similar brands) Capacity: runs 1-2 flow pumps simultaneously for hours after a power loss Expandable: connect two battery backups together to double runtime on a single pump Includes: power supply, pump adapters, user guide Mount: compact form factor, wall or stand mountable Power outages happen for more reasons than storms — scheduled utility maintenance, accidents damaging lines, or a tripped breaker can all cut power with no warning. A battery backup on your circulation pump is one of the cheapest insurance policies against losing livestock to an outage.Compatible with: most 12-24V aquarium pumps.
