What we found

Matched to a device: Minn Kota Terrova 55 lb (54" shaft, wireless remote), by setting each maker's published figures against the other — neither names the pairing.
Specifications are published for it, each with its source.
1 figure is contradicted by another credible source. Both readings are shown below, and neither is presented as the correct one.

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.
Only a comparison of two published figures — this battery's 105 amp-hours and 205 minutes of reserve capacity against Minn Kota's stated minimums of 105 and 180 — check yours before buying.
Minn Kota state a general requirement in this motor's own manual, about any battery rather than about this one: "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." The figures it is compared against here were read from the battery maker's own specification guide, which is the source cited below. Minn Kota ask for at least 105 amp-hours in the manual, and at least 180 minutes of reserve capacity where no amp-hour figure is given. This battery gives 105 and 205. Neither company mentions the other. Minn Kota also tell readers that a battery rated in cold or marine cranking amps is not designed for a trolling motor and should be avoided; U.S. Battery publish a CCA for this one, under a heading reading Flooded Lead-Acid Deep Cycle Batteries.

Do not charge with

The manufacturer states these chargers must not be used with this battery:

PD4500LI Series Power Control CenterStated incompatibleView charger: PD4500LI Series Power Control Center →
Progressive Dynamics state it outright about this converter: "The 4500LI series converter/chargers are designed to recharge lithium iron phosphate (LiFePO4) batteries only. DO NOT USE TO RECHARGE LEAD/ACID BATTERIES!" This pack is Flooded lead-acid, which is a lead-acid chemistry, so their sentence covers it. They say nothing about packs of other chemistries and nothing here extends it past what it covers.
