What we found

Matched to 2 devices: Minn Kota Terrova 80 lb (60" shaft, wireless remote), Minn Kota Terrova 55 lb (54" shaft, wireless remote), by setting each maker's published figures against the other — neither names the pairing.
20 specifications are published for it, each with the source it was read from, 1 of them corroborated by a second source.
No matching recall was found in the records this catalogue holds from 7 regulators.

Assembled from the evidence on this page. Every figure and count below is shown with the source it was read from.

Battery and charging

Energy: 5.888 kWh at half-C and 25°C
Voltage: 12.8V, from 3.2V cells
Rated capacity: 460Ah, from 230Ah cells
Rated charge cycles: More than 3,500 cycles — at 25°C, 0.5C in, 1C out, 70% depth
What counts as the end of its life: End of life is 70% of the original capacity
How the cells are arranged: 4S2P — four cells in series, two strings
Charging voltage: 14.6V maximum, which is 4 × 3.65V at the cell
Voltage it cuts off at: 10V, which is 4 × 2.5V at the cell
Highest charge current it will take: 230A continuous charging
Maximum continuous discharge: 230A continuous, at 25°C and half charge
Peak discharge: 500A — for thirty seconds, at half charge, when new
How fast it loses charge sitting idle: 3% a month at most, measured full and at 25°C
Series and parallel limit: Up to 4 in series or 16 in parallel

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 460 Ah and 230 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".
Minn Kota Terrova 80 lb (60" shaft, wireless remote)Figures compared
Two of these, wired in series for 24 V.
Two in series give 25.6 V and 460 Ah — nearly four times the top of Minn Kota's guidance band, which is a very long day rather than a fault. Epoch permit four strings. Each pack sustains 230 A against a 56 A draw. Worth knowing before buying two: each weighs 40 kg and the pair is 530 mm long apiece, so this is a fitted installation rather than something lifted in and out. 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.

Compatible platforms

The motors this pack is documented to run are listed above. No boat, rig or other platform in this catalogue is listed as carrying it — that is a separate question from what it will power, and nothing is listed until a source answers it.
