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

Can I charge my phone directly from this battery?

Extra battery for Ecotric Leopard

I bought an extra battery to increase my ebike range. Of all the sites I looked at, I was sure this one would fit my battery mount because it was labeled correctly. Not true of other sites. They shipped quickly and the battery was packed properly. Good business--would easily buy from this site again.

Excellent customer service

The whole process from ordering through receipt with Off Grid Lux was seamless. They responded quickly to our initial questions and helped us decide on the best product to suit our needs. There was a small hiccup with the shipment delivery (the fault of the carrier) and Odd Grid Lux contacted the carrier immediately and had our issue resolved. We researched many vendors before deciding on Off Grid Lux and their pricing and customer service cannot be beat.

Battery works and lasts a long time!

I bought this battery to replace my battery that died in my Ecotric 20810 (the fat tire one from around 2019 timeframe). Went on a 2+ hour ride and still had plenty of juice to spare. Wish it was cheaper but....it's a big battery and that's the retail price I guess.

Rockstar Customer Service

Ordered four inverters for a customer whose solar system was damaged by a utility surge. OffGridLux advertised these inverters at $2500. Upon ordering the inverters I was assured they were in stock and would be delivered. The next day I received a refund and the price of the inverters went up from $2500 to $3100 on the OffGridLux website. Chris in customer service explained the inverters were a new product and the $2500 price was added by mistake and the real price was $3100. He also told me his warehouse made a mistake they only had 2 of the 4 available. After expressing my frustration at the situation since the customer was already quoted the lower price, Chris worked out a deal and gave us the inverters at cost to OffGridLux for $2850 instead of $3100. Chris promptly adjusted the charge and made sure the 2 inverters were shipped out asap. As a small business owner I understand how small mistakes can be costly and sometimes the little things are the biggest problem. In good fashion Chris represented OffGridLux and my interests by communicating and figuring out an amicable solution for all parties involved. Thank you again Chris. You sir a true asset to your company.

Nice bike love the looks not as powerful as my pro 2 as one might expect but overall nice bike i did take it on a 47 mile trip and still had 50.1 percent left when i got home so no need to worry about a battery the best part of this bike is the company that sold it. I've been so impressed with this company which is why i purchased my 2nd bike from them they are nothing short of exceptional buy with confidence they are with your every step of the way and very fast to respond to emails and help with any problem ive come across i wish they sold other bikes just so i could buy from them off the grid lux is by far my favorite store keep it up guys I'll keep looking to see what you stock next
