The Dakota Lithium 12V 100Ah Deep Cycle Heated LiFePO4 Battery delivers 1,280Wh of reliable house power with built-in Even-Heat technology for all-season performance. At 27.55 lbs—60% lighter than equivalent lead-acid—it fits BCI Group 24 compartments and handles trolling motors, RVs, solar storage, and marine systems with 100A continuous discharge and up to 5,000 cycle lifespan.

Even-Heat is Dakota Lithium’s internal heating system that activates automatically when the battery detects charging below 0°C (32°F). It warms the cells to 5°C before allowing charge current to flow, preventing lithium plating damage that ruins unheated batteries in cold weather. You can fish or camp through winter without worrying about charge damage.
No. Standard lead-acid chargers output 14.8-15.5V with equalization stages that damage LiFePO4 cells. Use a LiFePO4-specific charger set to 14.4V. The Dakota Lithium 10A and 20A chargers are purpose-built for these batteries.
At 27.55 lbs vs ~65 lbs for equivalent AGM, it’s 60% lighter. The 5,000 cycle rating means ~10x longer life than lead-acid’s 300-500 cycles. You get 100% usable capacity vs lead-acid’s 50% recommended depth of discharge—so this 100Ah battery gives you more usable energy than a 200Ah lead-acid.
No. This is a deep cycle only battery with no CCA rating. For dual-purpose (deep cycle + engine starting), look at the DL+ line—the DL+ 12V 60Ah and DL+ 12V 135Ah both offer 1000 CCA cranking power alongside deep cycle capability.
Up to 4 in series (48V) or 4 in parallel (400Ah at 12V). For mixed series-parallel banks, follow Dakota Lithium’s wiring guidelines and use batteries of the same age and state of charge.
Backed by Dakota Lithium’s industry-leading 11-year manufacturer warranty—the longest in the LiFePO4 market. Certified to UL1642 (cell safety), IEC62133 (portable battery safety), UN 38.3 (transport safety), and manufactured in ISO 9001:2015 facilities.
