Product Description
Dakota Lithium DL+ 12V 320Ah self-heated lithium battery is our most compact and powerful battery yet. Ready for long expeditions in your RV, extended ocean voyages in your boat, or plenty of power for your off grid system. Engineered for maximum energy density, Dakota Lithium has packed 320Ah of capacity in a waterproof battery case the size of a single Group 31 battery, and now features internal heating for year-round performance. That’s 6X the amount of usable power of a single Group 31 AGM battery.

Internal Even-Heat Technology
Allows battery to be charged in freezing conditions. When charging the battery in temperatures below 0°C/32°F, the internal heating element is powered on by the charger and will warm the cells to 5°C/41°F. This increases the lifespan, performance, and efficiency of the battery.
Marine Grade & Waterproof
IP65 water resistance rating. Appropriate for marine environments, not submersible.
Charging Time
To estimate the charging time required with different amperage chargers, see our How To Calculate Battery Charging Time article or use this Battery Charge Time Calculator.
How Many Ah's do I need?
To calculate how long a battery will last on a single charge when powering your devices, please reference the Calculating Battery Capacity section of the linked article to ensure you are selecting the right capacity battery for your needs.
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 20A Charger - The most economical option. Must be disconnected when charging is complete.
- Dakota Lithium 50A Charger - Fast charging combined with onboard charger convenience. Must be disconnected when charging is complete.
- NOCO Genius Pro 25A Charger & Maintainer - Charges at 25 amps and then maintains the battery 24/7. Connect it and forget it convenience.
Alternator Charging
We do not recommend this battery for automotive or other applications where it would be charged directly off an alternator. To be charged off an alternator, this should be an auxiliary battery and a DC-DC charger like the Orion-Tr Smart Charger installed in order to charge the battery at LiFePO4 acceptable voltages.
