Epoch 48V 100Ah Server Rack LiFePO4 Battery (Self-Heating, Victron-Ready)

The Epoch 48V 100Ah Server Rack battery is a 3U rack-mount LiFePO4 module built for energy-storage and backup systems — the kind of stackable 48V bank that pairs with Victron, Sol-Ark, Solis, Growatt, and other inverters over closed-loop communication. It adds integrated self-heating so the bank can charge safely in cold spaces, and scales to large capacities by simply adding modules in parallel.

It speaks CAN and RS485, so a Victron GX device can manage charging and report state of charge across the whole stack.

Key Features

• 3U rack-mount form factor — standard server-rack sizing for clean, stackable installations.
• Self-heating — warms the cells for safe charging down to −10°C (14°F).
• Closed-loop communication — CAN and RS485 for managed charging with Victron GX and other major inverter brands.
• Massively expandable — up to 32 modules in parallel, plug & play.
• Smart BMS — over-charge, over-discharge, over-current, short-circuit, and temperature protection.
• 6,000+ cycle life, maintenance-free.
