DL 12V 100Ah Lithium Battery: The Legendary Deep-Cycle Workhorse

The DL 12V 100Ah is the industry standard for reliable, long-lasting deep-cycle power. Engineered into a versatile Group 31 (and Group 27 compatible) case size, this battery is the go-to upgrade for those looking to replace heavy lead-acid banks with a lighter, high-performance solution. With a full 100 Amp Hours of capacity, it provides the steady, consistent energy required for long days on the water or extended off-grid stays.

Built with premium Lithium Iron Phosphate (LiFePO4) technology, the DL 100Ah delivers twice the usable power of a traditional lead-acid battery while weighing 60% less. Whether you are powering a trolling motor, an RV house bank, or a solar energy system, this battery ensures you “get all the juice down to the last drop” thanks to its signature flat voltage curve.


DL 12V 100Ah Lithium Battery Key Features:

  • Exceptional Deep-Cycle Capacity: 100 Amp Hours of clean, stable power (1,280 Wh), providing a full day of run-time for high-draw trolling motors or RV electronics.

  • Drop-In Group 31 Compatibility: Fits perfectly into standard Group 27 and Group 31 battery boxes, making it an easy, space-efficient upgrade for marine and automotive setups.

  • Ultra-Lightweight Design: Weighing only 31.9 lbs, it significantly reduces the total weight of your boat or vehicle, improving speed and fuel efficiency.

  • Internal BMS Protection: Equipped with an active Battery Management System that handles cell balancing and protects against short circuits, overcharging, and extreme temperatures.

  • Legendary Durability: Rated for 2,000 to 5,000+ cycles, outlasting traditional batteries by up to 10X and providing an unmatched return on investment.

  • Cold Weather Performance: Optimized for rugged environments with a discharge range down to -4°F, ensuring reliability for winter warriors and ice fishermen.


Versatile Setup

The DL 12V 100Ah is designed for flexibility. It features M8 bolt terminals for secure connections and can be easily linked in series or parallel to build 24V, 36V, or 48V systems. This makes it the ideal choice for Marine Trolling Motors, RV Boondocking, Solar Storage, and Emergency Backup.

Note: This is a dedicated deep-cycle battery and is not designed for starting gasoline engines.

Recommended Charger: 12V 10A LiFePO4 Charger (sold separately).

Technical Specifications

  • 2 Year Warranty: Open Box Warranty
  • Storage Capacity: 100 Ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 135 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.
  • Voltage: 12.8V (Dakota Lithium 12V batteries can be used in series for up to 48V systems)
  • Size: 12.9"L X 6.7"W X 8.46H (328mm X 172mm X 215mm)
  • Energy: 1280wh (Watt Hours)
  • Terminals: M8 bolt size. (Max torque 15 ft. lbs.)
  • Weight: 30.86lbs (14kg) Thats 65% lighter than standard SLA batteries
  • Lifecycles (battery lifespan): Up to 80% capacity for 5,000 cycles in recommended conditions. The typical automotive SLA has 500 cycles. Dakota Lithium batteries last so long that the price per use is a fraction of traditional batteries.
  • Charge: 100A max, 14.4V recommended, 100V max. Please note: this battery should be charged between 32°F to 113°F (0°C to 45°C) and with a LiFePO4 compatible charger.
  • Discharge: 100A continuous, 180A max pulse. This battery is a great option for trolling motor applications and other 12V deep cycle uses. For golf cart setups or higher demand applications, we recommend using our DL+ line. This model is not intended for golf cart use
  • Includes active BMS protection: Contains a high discharge capable circuit that handles cell balancing, low voltage cutoff (10V) preventing over discharge, high voltage cutoff (15V) preventing over charging, short circuit protection and temperature protection for increased performance and longer life.
  • Certifications: Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 and UN 38.3 standards. They meet all US and international regulations for air, ground, and train transport.
  • ISO 9001:2015: Dakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.
  • IP 65 Rating: Protected from dust and resistant to low-pressure water from any direction, but not designed for submersion.
  • Series or Parallel: BMS can support wiring these batteries in series or parallel for up to 4 units (up to 48V series) **Not compatible with Golf Carts, for those applications choose the DL+ line
  • Charger Sold Separately: This battery should be charged using a LiFePO4 compatible charger. Dakota Lithium 12V batteries should be charged at 14.4 volts. Lead acid chargers will work, but will only charge the battery to 80% of capacity.

Open Box, Refurbished & Scratch and Dent Inventory

These batteries are not considered brand-new inventory, but they are fully functional, tested, and ready for use. Each unit has been inspected by our team to ensure it meets Dakota Lithium performance standards.

Most units were purchased, shipped, and briefly handled or installed before being returned. In many cases, customers realized they needed a different capacity, voltage, or configuration after receiving the product. Because of this, the battery cannot be returned to new inventory.

Cosmetic condition may vary. This can include light surface scratches, minor scuffs on the case, or slight wear on labels or silk screening from normal handling, unboxing, or installation. These are cosmetic only and do not impact performance.

These batteries have not been used for extended periods and are, in most cases, functionally close to new. Discounted pricing reflects cosmetic condition and inventory classification, not a reduction in performance.

This category may also include legacy models replaced by newer versions. These products will be sold until inventory is depleted and will not be restocked.

If you want a battery in perfect cosmetic condition, purchase a new unit from our standard lineup.

All applicable warranty terms apply as outlined in our warranty policy. Review warranty details before purchasing. For questions about fitment, condition, or performance, contact sales@dakotalithium.com.
