Deka Duration DD460-12H 12V 460Ah LiFePO4 Heated Battery
Deka Duration DD460-12H — 12V 460Ah LiFePO4 Heated Monobloc Battery
The Deka Duration DD460-12H is a 12V 460Ah LiFePO4 Heated Monobloc Battery built on Lithium Iron Phosphate chemistry with a fully integrated Battery Management System (BMS) and built-in self-heating capability. Rated at 460Ah with 5.5kWh of usable energy, it is the highest-capacity heated monobloc in the Deka Duration lineup — engineered for the most demanding high-capacity applications in cold climates that require deep, repeated cycling — including large off-grid solar storage, heavy-duty RV and marine house loads, golf carts, and home backup power systems — all in a sealed, IP67-rated, fire-resistant package that charges reliably down to -4°F (-20°C).
