Battery and charging

Energy: 2112 Wh
Internal resistance: 40 mΩ or less
Recommended charging: 14.4 V CC/CV, 33 A recommended
Series and parallel limit: Series is allowed only if it is NOT also starting an engine
Most it will take from an alternator: 165 A from an alternator, more than from a charger
Most it will take from a charger: 150 A from a charger; 33 A is what they recommend
Cranking amps, hot, marine and cold: 1500 A hot, 1300 A marine, 1200 A cold
Cycles or starts — not both at once: 4000 cycles or 5000 starts — but not both at once

Battery care and safety

Ingress protection: IP67
Charge current the heater needs to run: The heater needs at least 15 A of charge current
Where to install it: In a waterproof box or raised above the bilge

Size and fit

Overall dimensions: 13 × 6.77 × 8.5 inch

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 165 Ah and 150 A continuous. 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".
