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:

A motor’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 manufacturer or a dealer before buying.

Minn Kota Terrova 55 lb (54" shaft, wireless remote)Figures compared
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.
The motor's maker asks for at least a 105 amp-hour rating. This pack is rated 105 Ah and 100 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".
Garmin Force Current (10–32 V, kayak)Figures compared
Two of these, identical to each other, wired in series for 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 105 Ah and 100 A continuous. Which of the two figures applies turns on what is inside this pack, and its chemistry is not published in anything we hold — so the stricter one is used. The pack's maker permits the series wiring this needs: "Max. 4 in parallel, 4 in series (4S4P)".
Minn Kota Terrova 80 lb (60" shaft, wireless remote)Figures compared
Two of these, wired in series for 24 V.
Two of these in series give 25.6 V and 105 Ah, which Epoch permit — their specification allows four in series and four in parallel. 105 Ah sits inside Minn Kota's 100–125 Ah lithium band AND meets the 105 they name for lead acid, so this pairing satisfies both of their capacity statements. Each pack sustains 100 A against a 56 A draw. One caution that is nothing to do with the motor: this pack is IP54, where Epoch's Pro series is IP67, and IP54 is splashes rather than immersion. Minn Kota's installation manual states their motors are designed for lead acid, that lithium holds a higher voltage for longer, and that running above 85% speed for a prolonged period could cause permanent damage to the motor.
Minn Kota Terrova 112 lb (60" shaft, CHIRP sonar, wireless remote)Figures compared
Three of these, identical to each other, wired in series for 36 V.
Only at 36 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 at least a 105 amp-hour rating. This pack is rated 105 Ah and 100 A continuous. The pack's maker permits the series wiring this needs: "Max. 4 in parallel, 4 in series (4S4P)". 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".
Garmin Force Pro (20–45 V, 50" and 57" shafts, brushless)Figures compared
Three of these, identical to each other, wired in series for 36 V.
Only at 36 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 the battery must be able to supply 60 A of continuous current. This pack is rated 105 Ah and 100 A continuous. Which of the two figures applies turns on what is inside this pack, and its chemistry is not published in anything we hold — so the stricter one is used. The pack's maker permits the series wiring this needs: "Max. 4 in parallel, 4 in series (4S4P)".
