Product Description

Dakota Lithium DL+ 12V 135Ah Lithium Battery

The Dakota Lithium DL+ 12V 135Ah is designed for maximum versatility and power. It delivers 135 amp hours of deep-cycle performance, 1,000 CCA of engine-starting capability, and built-in even-heat technology for reliable operation in extreme cold. Whether you’re starting a vehicle, powering high-demand audio systems, running trolling motors, supporting golf carts, or energizing electronics, this battery is made to do it all. Engineered to perform in harsh conditions, it can charge and operate in temperatures as low as -20°F. With support for alternator charging, it replenishes up to 5× faster than conventional batteries—fully charging in about an hour when paired with a 135A charger or alternator.

Designed with exceptional energy density, it delivers five times the power of traditional batteries and fits into a Group 24 case that is 25% smaller than a standard 100Ah lithium model. Built on Lithium Iron Phosphate (LiFePO4) chemistry, it provides long-lasting power, half the weight of lead acid, and up to five times the lifespan. As a dual-purpose battery, it supplies strong starting power along with consistent deep-cycle performance, making it ideal for engines, audio systems, machinery, golf carts, marine setups, and other high-draw applications. It includes a terminal adapter kit for easy compatibility with automotive and marine connections, and it can be linked in series for 24V, 36V, or 48V systems. Backed by an 11-year warranty.

Ideal Uses for the Dakota Lithium DL+ 12V 135Ah

  • Car and truck engine starting

  • Deep-cycle power systems

  • Trolling motors

  • Truck and overland builds

  • RV and camper battery upgrades

  • High-performance car audio

  • Golf carts and lightweight EVs

  • 24V / 36V / 48V series banks

  • Industrial equipment

  • LiFePO4 replacement for SLA 12V batteries

  • Fish finders, flashers, and marine electronics

  • Recreational vehicles and trailers

  • Off-grid homes and cabins


Why This Battery Stands Out

This model uses premium LiFePO4 cells known for long service life—over 2,000 recharge cycles, or roughly five years of daily use. Its internal heating system allows dependable winter performance down to -20°F. With five times the power and half the weight of lead-acid batteries, it offers outstanding long-term value.
