IceCap Backup Battery v3

IceCap Battery Backup Version 3.0 for Aquarium DC Pumps (IC-BTBK3)

The IceCap Battery Backup Version 3.0 (SKU: IC-BTBK3) is an authentic, emergency power-reserve module distributed by CoralVue to insulate sensitive marine reef and freshwater aquariums from catastrophic power outages. In a closed aquatic ecosystem, a sudden loss of water circulation is an immediate, high-stakes emergency. Without continuous surface agitation and internal cross-flow, dissolved oxygen levels can plummet to toxic, lethal thresholds in as little as 4 hours—long before ambient water temperature drops become an issue. The IC-BTBK3 acts as your tank's dedicated insurance policy, stepping in the exact millisecond municipal power drops out to keep critical water-moving powerheads humming uninterrupted.

What truly separates the IceCap Version 3.0 from competing single-brand backups is its open compatibility profile. Rather than restricting you to a single manufacturer line, this unit ships with an array of standardized connecting cables and adapters. This makes it fully compatible with major variable-speed wavemakers like the Maxspect Gyre series, IceCap Gyre setups, and Reef Octopus Octo Pulse lines. Internally, the v3.0 utilizes a robust 2.5Ah cell capacity balance designed to safely feed the demanding voltage rails of modern DC wavemakers. Packing massive power into a highly compact, aesthetic housing, it provides the peace of mind needed to withstand seasonal rolling blackouts, localized transformer blowouts, or severe weather events without risking a total system crash.

Key Features

• Protects Complex Livestock Investment: Preserves expensive, slow-growing coral colonies and high-end fish species by maintaining the vital gas exchange loop when the main grid fails.

• User-Serviceable Fast-Blow Fuse: Outfitted with an integrated, easily accessible 250V 10A fast-blow safety fuse to protect both the battery cells and connected pump controllers from sudden external electrical surges.

• Zero Sump Flood Risk: By focusing emergency power strictly on internal display tank flow pumps rather than your main return pump, it ensures the sump won't overflow or break siphon loops during an outage.

• (Note: This emergency power package includes the standalone v3.0 battery backup chassis, the dedicated 27V DC wall charger adapter brick, dual connection installation cables, and multi-pump adapter tips. It is NOT natively compatible with EcoTech Marine, AI Nero, Tunze, or Reef Octopus VarioS return pumps).
