Epoch's own 24-volt charger and Epoch's own 24-volt LiFePO4 pack. Their page states the charger is "intended for compatible 24V LiFePO4 batteries" — a class, not this SKU, so the row is as specific as they were.

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.

Neither company has named the other, and the two figures are different kinds of number: Minn Kota's is a peak draw, Epoch's is a continuous rating.

The comparison therefore runs the cautious way round, since a pack that can supply its figure indefinitely covers a motor's worst moment; read the other way it would mean nothing.

Epoch do publish this pack in a collection titled "Lithium Batteries for Minn Kota Trolling Motors", which names the motor brand but no model.

One of these, on its own, at 24 V.
Only at 24 volts, and on published figures — neither maker has named the other and nobody has tested this pairing — check yours before buying.
The motor's maker asks for 100 Ah minimum for a lead-acid or AGM battery, and 50 Ah to 100 Ah where the battery is lithium, and a 40 A continuous draw, which the circuit breaker is specified against. This pack is rated 100 Ah and 120 A continuous.

Only at 24 volts, where Minn Kota rate this motor at 56 A and Epoch rate this pack at 120 A continuous — check yours before buying.
Minn Kota state this 80 lb motor runs on a 24 volt system and draws up to 56 A. Epoch state this pack is 25.6 V with a maximum continuous discharge of 120 A, leaving 64 A of headroom.
