DEKA Duration DD460-12H 12V Heated LiFePO4 Battery

DD460-12H Heated Monobloc LFP Battery

The Deka Duration DD460-12H is a drop in replacement for Group 8D VRLA batteries and delivers 460Ah of lithium iron phosphate energy storage at 12.8V nominal for 5.89 kWh of usable capacity per unit. Engineered for cold-climate off-grid solar, commercial energy storage, industrial backup power, and marine applications, this monobloc battery includes a built-in low-temperature heater that automatically activates when battery temperature drops below 32°F.

Rated for 6,000 cycles at 80% depth of discharge, the DD460-12H combines exceptional longevity with year-round reliability for demanding installations in all climates. The sealed ABS+PC fire-rated enclosure with IP67 rating provides dust and water resistance for outdoor environments, while included busbars simplify terminal connections for scalable parallel and series configurations.

Deka Duration DD460-12H Battery Features

• LiFePO4 Chemistry: 12.8V nominal lithium iron phosphate cells deliver 99% round-trip efficiency with 100% usable depth of discharge.
• Integrated BMS: Internal Battery Management System provides short circuit protection, over-discharge voltage cutoff, cell balancing, and smart communication.
• Scalable System Design: Supports up to 16 in parallel or 4 parallel by 4 series configurations. Includes busbars for combining terminal connections.
• Built-in Low-Temperature Heater: Automatically activates when cell temperature drops below 32°F (0°C), warming the battery to 50°F (10°C) before charging begins.
• Drop-in Replacement: Group 8D footprint with M8 bolt threaded insert terminals allows direct replacement of existing lead-acid batteries.
