Dakota Lithium

Dakota Lithium offers several different answers to a power problem: small batteries for electronics, larger deep-cycle batteries, DL+ dual-purpose models, and portable power stations. Start with the load and charging arrangement, then choose the product family.

Four useful places to start

For a dedicated fish finder or other compatible low-draw device, the 12V 10Ah battery is the compact option in this selection. A small battery makes sense when the device needs modest current and the goal is a manageable, separate power supply.

The 12V 100Ah heated model serves a different role: larger deep-cycle loads. Dakota explicitly says this model is not for starting engines. Its heated designation also matters when comparing current listings with older stock.

The DL+ 135Ah adds starting capability to deep-cycle capacity. A dual-purpose label is a reason to investigate compatibility with the particular engine and charger, not a promise that every existing installation can accept the swap.

For ready-access outlets, the PS2400 combines storage and power electronics in a portable enclosure. It suits a different buying decision from installing a bare battery: compare the outputs you need, the equipment you would otherwise add, and whether the unit will be moved between uses.

Match the battery to the whole system

Write down the equipment voltage, expected current, required operating time, physical space and charging source. Then check those requirements against the exact model. Capacity alone does not tell you whether a battery can supply a motor’s current or start an engine. Heating and charging restrictions are also model-specific.

Our fishing-battery guide walks through these choices. For camp and backup power, see battery versus PS2400.

Who owns Dakota Lithium

Dragonfly Energy — the company behind Battle Born Batteries — bought the Dakota Lithium brand on 31 July 2026. Dragonfly’s SEC filing describes the purchase of “substantially all of the operating assets associated with the Dakota Lithium® brand” for $4.0 million: $1.0 million in cash and 1,500,000 shares valued at $2.00 each. The filing says Dragonfly “intends to operate Dakota Lithium as a distinct brand alongside Battle Born Batteries®.” It does not name the seller, and it says nothing about warranty coverage for batteries bought before the sale.

Two things follow for a buyer. Battle Born and Dakota Lithium are now sibling brands under one owner, so a comparison between them is a comparison within one company’s range. And the warranty changed with the owner. Dakota’s warranty FAQ now states that Dragonfly Energy “did not assume the prior company’s warranty obligations when it acquired the Dakota Lithium brand”: the current terms apply to products sold on or after 1 September 2026, and anything bought earlier goes through a “Legacy Customer Support Program” in which, in Dakota’s words, “any assistance provided through this program is a voluntary goodwill accommodation.” An 11-year warranty bought in 2025 is therefore not the 11-year warranty described on the product page today. If you own an older Dakota battery, read that page before you need it. The site’s footer says only “Powered by Dragonfly Energy”; the change of owner is not otherwise explained on the site.

Read the warranty for the product you buy

The selected standalone batteries advertise an 11-year manufacturer-defect warranty. The PS2400 product page instead states three years. Warranty length is not a promised service life, and conditions matter; retain your receipt and consult Dakota’s warranty and returns information for the purchase in question.
