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. 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 270 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".
