Product Description

This 12V lithium battery with 20Ah capacity replaces Dakota Lithium's 18Ah battery. Nearly the same dimension but with 11% more capacity make this a great choice as a lithium fish finder battery, but its light weight makes it equally well suited for powering any small 12 volt portable electronics while camping, ice fishing or any time you're on the go and off grid. Equipped with a built-in voltmeter, USB-C and USB-A ports. Engineered in a 12Ah SLA case, but with 20Ah of Lithium Iron Phosphate (LiFePO4) technology, this battery has three times the power, half the weight, and lasts 4 times longer than a 12Ah sealed lead acid battery – providing exceptional performance & lifetime value. Optimal performance down to minus 20 degrees Fahrenheit for winter warriors. 20Ah hours of capacity provides a full day of power for high amp draw electronics like Garmin fish finders, ice augers, or anything where you need a longer run time. Same performance as our legendary 10Ah battery, but with 100% more capacity. Drop in replacement for 12Ah SLA batteries (same size, physical dimensions & terminals) but with three times (3X) longer run time. Lithium deep cycle battery durability, backed by an 11 Year Warranty. LiFePO4 compatible charger required.

Common Applications:

  • Fish Finders, Flashers, & Boating Electronics
  • Garmin Fish Finders
  • Ice Fishing
  • LiFePO4 Replacement for SLA 12V
  • Mobility Scooters
  • 24V Electric Bikes & Scooters
  • Robotics
  • Hunting, Camping, And Trail Cameras
  • Replacement Battery for Hammer-Head Remora Pool Vacuum

11 Year Warranty
Every Dakota Lithium battery comes with a best in class, 11 Year Warranty.

20 ampere hours. Dakota Lithium batteries provide consistent power for all 20 amp hours. 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, especially in cold temperatures. You get all the juice down to the last drop.


240 Watt hours (Wh)

Standard F2 terminals (6.35mm or 0.25" wide male spade).

6.125" x 3.95" x 3.88" (156x100x99mm)(LxWxH). Replaces 12Ah 12V SLA Batteries.

4.3 lbs (1.9Kg). That's 60% lighter than a SLA battery.

Lifecycles (Battery Lifespan)
Up to 80% capacity for 3,000 cycles in recommended conditions. The typical SLA has 500 cycles. Dakota Lithium batteries last so long that the price per use is a fraction of traditional batteries.

Operating Temperature
Ideal for rugged & harsh environments. Much better than SLA or other lithium’s. -20°F min, +120°F max optimal operating temps (battery performs well down to -20°F). Avoid charging below 32°F.

18A max continuous, 50A max pulse (<3 sec). The flat discharge voltage curve provides 75% more usable capacity than a SLA 20Ah battery. Please note: for trolling motors with 30lbs + of thrust we recommend combining two batteries in parallel to create a 36 amp continuous discharge rate and 36Ah of capacity. This increases runtime and lifespan of the battery.

9A max, 14V max recommended, 15V max. Please note: this battery should be charged using a LiFePO4 compatible charger.  Select the option to bundle with a Dakota Lithium battery charger and save $5.

Includes Active BMS Protection
Every Dakota Lithium battery contains a Battery Management System (BMS) that handles automatic cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life.

Series or Parallel
BMS can support wiring these batteries in series or parallel for up to 4 units (up to 48V series or to 12V 80Ah parallel).

Charger Sold Separately
This battery must be charged using a LiFePO4 compatible charger. Option to bundle and save with Dakota Lithium charger is available.

All batteries are UN 38 certified. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. Meets all US & International regulations for air, ground, and train transport.
