What we found

Documented to power devices: Minn Kota Terrova 112 lb (60" shaft, CHIRP sonar, wireless remote), Minn Kota Terrova QUEST 90/115 lb (45" shaft, CHIRP sonar, wireless remote), from the manufacturer's own documentation.
Matched to devices across several brands, by setting each maker's published figures against the other — neither names the pairing.
Specifications are published for it, each with its source.
2 figures are contradicted by another credible source. Both readings are shown below, and neither is presented as the correct one.

Size and fit

Overall dimensions: 13 × 6.77 × 8.5 inch
Torque for the battery terminal nuts: 12 to 14 N·m on the M8 terminal bolts
Case size: Group 31 — one case in place of three batteries
Case material: ABS
Terminal thread: M8 × 1.25 mm posts, both terminals
Group size the maker names: Fits a group 31A tray, 24 mm short of it

Compatibility

Motors it will run, and how many packs: Sources disagree
What packs must share to be wired together: Identical packs, same brand, bought within a month
What it replaces: Replaces three 12 V 50 Ah lead-acid batteries

Devices documented to run on this

Some rows below are marked FIGURES COMPARED. On those the figures line up and neither manufacturer states that the pack runs the 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, at 36 V.

“This product is suitable for 36V trolling motors up to 120lb thrust.”

Only within LiTime's ceiling of 120 lb of thrust for a 36 volt motor — check yours before buying. The rows below without a line of their own are within that ceiling.

The two makers do not agree here. The battery maker's thrust rule covers this motor, but the motor's own documentation asks for 60 A continuously and this pack is rated for 50 A. Both statements are recorded; neither has been resolved in favour of the other.

One of these, on its own, wired at 36 V.
Only wired at 36 volts, where this motor is rated 115 lb and LiTime's ceiling for a 36 volt motor is 120 lb — check yours before buying.
Minn Kota's manual for this motor says three 12-volt batteries are required at 36 volts; this is one pack. Minn Kota publish a maximum draw of 58 A for this motor and say it occurs only intermittently; LiTime rate this pack at 50 A continuous, 60 A for up to thirty minutes and 250 A for one second. This motor's own manual says the QUEST series is optimized for LiFePO4 cells, so the 85% speed limit its older siblings carry does not apply to it.

The two makers do not agree here. The battery maker's own rule covers this motor, quoted above. The motor's maker asks for at least a 105 amp-hour rating, and this pack is 50 Ah. Both statements are recorded and neither has been resolved in favour of the other. Minn Kota's manual for this motor says three 12-volt batteries are required; this is one pack, in the case size of a single lead-acid battery. Minn Kota publish a maximum draw of 52 A for this motor and say it occurs only intermittently; LiTime rate this pack at 50 A continuous, 60 A for up to thirty minutes and 250 A for one second. Minn Kota add a condition LiTime do not: this motor is designed for lead-acid, and running it above 85% speed for a prolonged period on lithium could cause permanent damage to it.
