User Manual

Dakota Lithium 12V 20Ah USB Deep Cycle LiFePO4 Battery Specifications

Category	Specifications
Warranty	11 Year Warranty
Capacity	20 Ampere hours. Dakota Lithium batteries provide consistent power for all 20 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, especially in cold temperatures. You get all the juice down to the last drop.
Voltage	12.8V
Energy	256 Watt-hours (Wh)
Terminals	F2 Terminals (spade socket). When used in salt water, or corrosive, environments we recommend applying a small amount of dielectric grease on the blades of each terminal. It helps extend the lifespan.
USB / Voltmeter	USB A & C ports provide easy charging for personal electronics. Voltmeter included for monitoring battery power levels.
Size	5.9" x 3.94" x 3.86" (151mm x 100mm x 99mm)
Weight	4.25 lbs (1.93Kg) That's 65% lighter then a SLA battery.
Lifecycles (battery lifespan)	Up to 80% capacity for 5,000 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.
Discharge	10A continuous, 20A max. Note: For small trolling motors, we recommend using our 12v 54Ah battery to maximize your time on the water
Charge	10A max, 14.4V recommended, 15V max. Please note: this battery should be charged using a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery.
Includes active BMS protection	Contains a circuit that handles 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)
Certifications	All batteries are UN38 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.
ISO 9001:2015	Dakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.
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.

Frequently-Asked Questions

They Stood By Me

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

Bruce D.

Awesome Service!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.

Jennene A.

Real Person, Honest Service.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.

Ray B.

Easy Return

I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!

Roger V.

Totally Off Grid.

I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
