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 215 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 M32215-S at 215 amp-hours each, 110 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' 215 amp-hours against the 105 that Minn Kota's manual asks for — check yours before buying.
Lithium Pros rate the M32215-S at 215 amp-hours, 110 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.

Two of these, Two 12-volt batteries wired in series.
Only on a comparison of two published figures — Lithium Pros' 215 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.

Minn Kota's manual for this motor is explicit that three 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 125 to 150 amp-hours for a 112 lb motor.
