Group the maker sells it as: BCI Group 31

Compatibility

What the manufacturer says it fits: any outboard charging system including Honda, Suzuki, all Mercury and all Yamaha

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.

Minn Kota's website battery guide asks for 110 amp-hours rather than the manual's 105, and they have not reconciled the two; at 110 this pack clears both.

Lithium Pros publish a reserve-minute figure for this pack and it names Minn Kota, which is not a statement that the two go together: their footnote assumes a 50% throttle setting on a Minn Kota motor and a 50% duty cycle, so it is a runtime estimate for one motor at one throttle position.

It is not the BCI reserve capacity — minutes at a fixed 25 amps — which is the measure Minn Kota's own requirement refers to, so the two numbers should not be set against each other.

Minn Kota attach a condition to the chemistry that no comparison of capacities can settle: this motor is "specifically designed to run on traditional lead-acid batteries", and "running a Minn Kota trolling motor at speeds higher than 85% for a prolonged period could cause permanent damage to the motor".

On charging they are the other way about — motors and Precision chargers made in 2021 or later carry a lithium profile, and earlier Precision chargers can charge lithium on the AGM setting.

Neither company has named the other and nobody has tested the pairing.

Lithium Pros rate the M3110-S at 110 amp-hours each, 5 amp-hours above it.

Minn Kota's own battery-guidance page (not the page cited below) also forbids mixing types in such a string: "Do not connect a Lead-Acid and Lithium in a series to create a 24-volt system", which rules out part-upgrading an existing lead-acid set.

One of these.
Only on a comparison of two published figures — Lithium Pros' 110 amp-hours against the 105 that Minn Kota's manual asks for — check yours before buying.
Lithium Pros rate the M3110-S at 110 amp-hours, 5 amp-hours above it. Minn Kota's battery-guidance table recommends AGM or lithium at 100 amp-hours for a 55 lb motor, alongside the manual sentence quoted above.

Only on a comparison of two published figures — Lithium Pros' 110 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.
Minn Kota's manual for this motor is explicit that two 12-volt batteries wired in series are required, and their amp-hour figure is asked of the battery rather than of the string. Their battery-guidance table recommends lithium at 100 to 125 amp-hours for an 80 lb motor.
