Description
Ultimate Marine Lithium Power Bundle — Everything Your Boat Needs for a Complete Upgrade
This bundle combines the best of Dakota Lithium engineering to deliver a full-system marine power upgrade: one 36V 60Ah LiFePO4 trolling-motor battery and two DL+ 12V 135Ah dual-purpose deep-cycle and cranking batteries. Whether you’re powering a high-thrust trolling motor, running advanced electronics, or starting your outboard, this setup gives you longer runtime, faster charging, and unmatched durability in all conditions.
The DL+ 12V 135Ah is the most versatile marine battery in its class—135Ah of deep-cycle capacity, 1,000 CCA of true starting power, and built-in even-heat technology for reliable performance down to -20°F. It’s a Group-24 footprint with the energy of a much larger battery, weighing half as much as lead acid and lasting 5x longer. Perfect for your outboard, electronics network, forward-facing sonar, pumps, or house loads. Meets Mercury Outboard lithium requirements and exceeds ABYC standards.
The 36V 60Ah LiFePO4 battery delivers all-day power for 36V trolling motors up to 120 pounds of thrust, with 5–8x the lifespan of lead acid and a fraction of the weight. Compact, rugged, and engineered for harsh marine environments, it provides a full day of fishing on a single charge. Pair with a 36V LiFePO4 charger for maximum performance.
Together, these batteries create a lightweight, high-output, long-lasting system that transforms your boat’s power profile. If you want faster charging, longer days on the water, stronger starts, cleaner installs, and dependable power in any weather, this is the complete upgrade.

You get all the juice down to the last drop.
-
36V 60Ah Storage Capactiy:
60 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 60 amp hours. DL LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized SLA batteries. You get all the juice down to the last drop.
