The Dakota Lithium DL+ 12V 135Ah is a dual-purpose Lithium Iron Phosphate (LiFePO4) battery designed to start engines and run deep-cycle electronics from a single unit. It fits a standard Group 24 battery case and is a direct drop-in replacement for most Group 24 and Group 34 lead-acid or AGM batteries.
Three things separate this battery from a standard AGM or lead-acid replacement:
-
Built-in cold-weather charging. An internal heating element automatically warms the cells before charging when temperatures drop below 32°F, allowing safe charging down to -4°F per manufacturer specifications. Standard lithium batteries cannot be safely charged below freezing.
-
Long cycle life. Rated by the manufacturer for up to 5,000 charge cycles to 80% capacity under recommended conditions compared to approximately 300–500 cycles for a typical AGM battery of the same size.
-
Dual-purpose engine start and deep cycle. Provides 1,000 CCA for cranking gasoline engines and 135Ah of sustained capacity for running electronics, trolling motors, and accessories without needing two separate batteries.
At 27.2 lbs, it is approximately 65% lighter than a comparable lead-acid battery, per manufacturer data. Includes an active Battery Management System (BMS) that handles cell balancing, overcharge protection, over-discharge protection, and short-circuit protection automatically.
Backed by an 11-year pro-rated manufacturer defect warranty. Meets ABYC marine standards and Mercury Outboard Motors lithium starter battery requirements. Certifications include UL1642, IEC62133, and UN 38.3.
Performance figures are based on manufacturer testing under recommended operating conditions. Real-world results vary depending on application, depth of discharge, temperature, and charging practices. Verify compatibility with your engine or charging system before purchase.
