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.
Minn Kota's manual for this motor asks for at least a 105 amp-hour rating.
What the capacities do not settle is what each maker says this kind of battery is for.
Epoch sell it as a "Dual-purpose cranking and deep-cycle LiFePO4 battery" and print 1,000 A at five seconds beside the 300 Ah.
Minn Kota say a cranking battery "is not suitable for use with an electric trolling motor because they focus on quick, strong burst of power to start your outboard engine vs long-lasting power for trolling motor use".
Their objection is to a battery built only for cranking and Epoch's claim is that this one is built for both — but Minn Kota have not said a dual-purpose pack answers it, and Epoch have not addressed Minn Kota.
Both sentences are here because neither company has resolved the other.
Minn Kota attach a condition to lithium that no comparison of capacities can settle either: this motor is "specifically designed to run on traditional lead-acid batteries", and running it above 85% "for a prolonged period could cause permanent damage to the motor".
Neither company has named the other and nobody has tested the pairing.
Epoch rate this pack at 300 amp-hours each, which clears that and their website guide's 110 as well.
Minn Kota forbid mixing types in such a string: "Do not connect a Lead-Acid and Lithium in a series to create a 24-volt system".
Neither company names the other and nobody has tested the pairing.
Compared on continuous figures only: nothing here is about surge.

One of these.
Only on a comparison of two published figures — Epoch's 300 amp-hours against the 105 that Minn Kota's manual asks for — check yours before buying.
Epoch rate this pack at 300 amp-hours, which clears that and their website guide's 110 as well. Epoch also publish a recommended continuous discharge of 150 A against a 300 A maximum, and the motor's 50 A peak draw is well inside the recommendation.

Two of these, Two 12-volt batteries wired in series.
Only on a comparison of two published figures — Epoch's 300 amp-hours against the 105 that Minn Kota's manual asks for, and with two of these wired in series as their manual requires — check yours before buying.
Epoch also publish a recommended continuous discharge of 150 A against a 300 A maximum, and the motor's 56 A peak draw is well inside the recommendation. This motor takes two 12-volt batteries wired in series; Epoch permit up to four of these in series, so three is inside their limit.
