What we found
- Matched to 1 device: MotorGuide R3 30 lb freshwater (12 V, 30" shaft, 5 forward/2 reverse), by setting each maker's published figures against the other — neither names the pairing.
- 7 devices are explicitly documented as NOT run by it.
- 15 specifications are published for it, each with the source it was read from.
- No matching recall was found in the records this catalogue holds from 7 regulators.
Assembled from the evidence on this page. Every figure and count below is shown with the source it was read from.

2,000 cycles at full discharge, up to 6,000 at a fifth of it
“HOW LONG WILL MY BATTERY LAST? The average lifespan of a Dakota Lithium Iron Phosphate battery depends on use. If the battery is used at maximum discharge (typically 1C) then the lifespan is typically 2,000 recharge cycles or roughly 5 – 10 years with regular use. When used at <0.2C discharge the lifespan increases, up to 6,000 recharge cycles.”

- Whether the warranty transfers on resale
- Original owner only; one exchange; accessories get 1 year
“Dakota Lithium offers a 11 year manufacturer's defect warranty from the date of purchase. The average lifespan of a Dakota Lithium Iron Phosphate battery is 2,000 recharge cycles, or roughly 5 – 10 years with regular use that is appropriate to what the battery is designed for (see the specifications of the battery). This warranty does not cover negligence or misuse of the battery or normal wear and tear.”

Certification claims
- The maker's own safety claim
- The maker calls them 100% safe and not prone to fire
- Company quality certification
- Sources disagree
The manual says ISO 9001:2008 where the website says 9001:2015
“CERTIFICATIONS - Tested and certified for safety and reliability Dakota Lithium batteries are UN 38 certified and built from grade A cells. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. UN Manual of Tests and Criteria certified, and meets all US & International regulations for air, ground, marine, and train transport. Select battery models are ISO Certified ISO 9001:2008 Quality Management System & ISO 14001:2004 Environmental Management System for use in industry applications.”

ISO 9001:2015 — a company standard, not a battery one
“ISO 9001:2015 Dakota Lithium is certified by ISO 9001:2015 for lithium battery engineering, manufacturing, and quality control. This means that the battery systems available at Dakota Lithium are designed and manufactured to the highest ISO 9001:2015 engineering standards.”

“ARE LITHIUM BATTERIES SAFE? Dakota Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries is not prone to exploding or catching fire due to the lack of oxide / oxygen in the LiFePO4 chemistry.”

Devices documented to run on this
The figures below line up. Neither manufacturer states that this pack runs this device — that is our reading of what each of them published separately, not a claim by either of them or a test by us. Even where every stated figure agrees, these can still decide it:
- A motor’s published draw is usually a peak, not the load it holds — the two numbers are not the same kind of quantity
- A maker’s amp-hour minimum and their reserve-capacity minimum can give different answers about the same battery
- Conditions attached to the chemistry, such as a speed limit for running on lithium
- Whether the pack may be wired in series at all, where the device needs 24 or 36 volts
- The charger, which both makers put conditions on and neither supplies
- Case size, hold-down and terminal type — fitting the space is not being secured in it
Worth confirming with the manufacturer or a dealer before buying.
One of these, on its own, at 12 V.
“Perfect for trolling motors with 30 lbs of thrust or less.”
Only within Dakota Lithium's ceiling of 30 lb of thrust for a 12 volt motor, which this motor's 30 lb is — check yours before buying.
Compatible platforms
The motors this pack is documented to run are listed above. No boat, rig or other platform in this catalogue is listed as carrying it — that is a separate question from what it will power, and nothing is listed until a source answers it.
