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:

The device’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 device's manufacturer or a dealer before buying.

One of these, on its own, at 12 V.
Only at 12 volts, and on published figures — neither maker has named the other and nobody has tested this pairing — check yours before buying.
Minn Kota ask for “at least a 105 amp-hour rating”, in a paragraph about lead-acid: “The motor will operate with any lead acid, deep cycle marine 12-volt battery/batteries. For best results, use a deep cycle, marine battery with at least a 105 amp-hour rating.” This pack is LiFePO4, prismatic cells. For a lithium pack the same maker's thrust-to-capacity table names a different figure for this motor: “55 lb AGM or Lithium 100Ah 2–4 hours Most common setup” Those are two of Minn Kota's own numbers for two different chemistries, and an amp-hour rating does not carry from one to the other, so they are set out here rather than compared. This pack is rated 120 Ah. Minn Kota attach a condition to the chemistry that no comparison of figures can settle: "speeds higher than 85% for a prolonged period could cause permanent damage to the motor".
