About Dakota Lithium

Editorially researched & verified

Dakota Lithium is a direct-to-consumer manufacturer of LiFePO4 (lithium iron phosphate) batteries sold under the domain dakotalithium.com. The company focuses on high-performance battery solutions for demanding outdoor, marine, RV, and off-grid applications. Its product lineup spans voltages and capacities from a lightweight 12V 4.5Ah powersports battery to a large-format 12V 320Ah dual-purpose unit designed for RVs and large solar systems.

The brand's flagship selling point is its 11-year warranty — one of the longest in the consumer LiFePO4 market — combined with a rated lifecycle of 2,000+ charge cycles. This long service life positions Dakota Lithium as a premium-but-cost-effective alternative to traditional lead-acid batteries when total cost of ownership is considered. Products feature built-in Battery Management Systems (BMS), IP67 waterproofing on select models, and Internal-Even Heat Technology for cold-weather performance.

Key product categories include Marine & Deep Cycle, RV, Van & Overland, Golf Cart & Electric Vehicle, Automotive & Powersports, and Solar Generators & Backup Power. The store also carries battery chargers, Victron inverter accessories, and wiring kits. Prices range from $159 for entry-level powersports batteries up to $2,299 (on sale $1,999) for the flagship 12V 320Ah heated dual-purpose model.

Shipping is handled via FedEx Ground for batteries under 70 lbs, with typical transit times of 1–5 business days within the contiguous US. Heavier units ship freight with a 5–8 business day window. A physical street address is required for all orders due to DOT regulations governing lithium battery transport, and a signature is required upon delivery. International shipping is available to select countries via FedEx or DHL, though customs fees may apply.
