The Epoch Batteries 12V 300Ah (3.84kWh) Pro Series was engineered for exactly those moments not the easy ones. This is a professionally spec'd, dual-purpose LiFePO4 powerhouse purpose-built for homeowners building serious backup systems, RVers who refuse to compromise, off-grid dwellers who live beyond utility lines, and mobile operators who measure downtime in dollars.\u003c\/p\u003e\n\u003cp\u003eWith 3.84 kilowatt-hours of clean, usable energy in a Group 8D form factor, built-in internal heating for sub-zero charging capability, native Victron CANBUS communication, IP67 waterproof and dust-proof construction, and 6,000+ cycle life backed by an 11-year manufacturer's warranty, the Epoch 12V 300Ah Pro Series doesn't just promise performance it delivers it, season after season, system after system.\u003c\/p\u003e\n\u003cp\u003eAt Outbound Power, power isn't a hobby it's what we do. We've helped homeowners build grid-independent backup systems, guided RVers through full battery bank upgrades, and helped off-grid builders design storage arrays that carry real loads through real seasons. We know these products because we know the applications they serve.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEpoch Batteries 12V 300Ah (3.84kWh) Pro Series Features\u003c\/h3\u003e\n\u003ch4\u003eThis Battery Keeps Charging Even in Freezing Cold Weather\u003c\/h4\u003e\n\u003cp\u003eBuilt-in internal heating lets this battery charge safely down to -4°F (-20°C). Most lithium batteries fail in winter.
