Product Description
This 12V lithium deep cycle battery from Dakota Lithium with 54 amp hours (Ah) of capacity is built for high performance in the most rugged of conditions. Engineered with Lithium Iron Phosphate (LiFePO4) technology this battery has twice the power, half the weight, and lasts 4 times longer than a lead acid battery – providing exceptional lifetime value. 54Ah's of capacity provides a full day of power for mid sized trolling motors or for long days on the open road in your RV. Ideal for deep cycle applications where you need lots of power for a long time. Easily link in series to create 24V, 36V, or 48V systems. Recently upgraded with the same capacity but in a smaller, lighter U1 marine plastic case. Built to endure with deep cycle lithium battery durability, backed by an 11 Year Warranty. LiFePO4 compatible charger required. Save 10% on a Dakota Lithium, X2Power or NOCO charger when bundled with battery using option above.

11 Year Warranty
Best in class, 11 year manufacturer defect warranty.
Storage Capacity
54 amp hours. Dakota Lithium batteries provide consistent power for all 54Ah's. 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)
Energy
648 Watt hours (Wh)
Terminals
M6 bolt terminals with hardware included. Easy to adapt to different connection needs (Max torque 15 ft. lbs).
Size
7.75” x 5.3” x 7.5” (LxWxH) - Group U1
Weight
12.6 lbs (5.7 Kg). That's 75% lighter than an 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 without a Battery Heater.
Discharge
60A max continuous, 100A max 10 second pulse. The flat discharge voltage curve provides 75% more usable capacity than a 54Ah SLA battery.
Charge
27A max, 14.4V recommended, 15V max. This battery must be charged using a LiFePO4 compatible charger. Save 10% on a Dakota Lithium 10A Charger, an X2Power 10A Automatic Charger or a NOCO 10A Charger/Maintainer when bundled with battery using option above. Dakota Lithium chargers should not be left connected for more than 16-24 hours. Use an automatic charger or maintainer for long term connectivity. See options below.
Multiple charging options are available with this battery to suit your various needs. 10% discount on a charger when bundled with battery using option above.
- Dakota Lithium 10A Charger - The most economical option. Must be disconnected when charging is complete.
- X2Power 10A Automatic Charger - Fully automatic charging for optimal battery health and extended battery life.
- NOCO 10A Charger & Maintainer - Charges and maintains the battery 24/7 for occasional use or off season storage.
Balancing
If this battery will be connected in series, please review Dakota Lithium's Balancing Instructions.
