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.
