What we found

  • Battery models are matched as running it across several brands, by setting each maker's published figures against the other — neither names the pairing, 15 of them needing more than one pack in series.
  • Marine-grade deep-cycle; lithium generally preferred.
  • 5 batteries are compared as NOT suitable for it, by setting each maker's published figures against the other — neither names the pairing.
  • Published as 33.9 A at speed 20 on a 12.8 V bank · 56.0 lbs at speed 20 on a 25.6 V bank.
  • Specifications are published for it, each with its source.
  • 1 figure is unconfirmed.

Standard the figures were measured under
ISO 13342, ±22 N and ±5 A

“These values are gathered based on the ISO13342 test setup, using the Garmin ® high efficiency propeller, in relatively calm water, with the motor deployed deeply enough not to ventilate, and with tolerances of ±22 N (5 lbf) and ±5 A. Voltage levels have been measured at the trolling motor power cable terminals.”

Battery type the maker recommends
Marine-grade deep-cycle; lithium generally preferred

“For best results, use a marine-grade deep-cycle battery designed for trolling motor applications. Lithium batteries are generally preferred because of their weight, performance, and charging characteristics, but the ideal battery depends on the specific vessel and installation. Consult the boat manufacturer or dealer for recommendations suited to your setup.”

Circuit breaker it requires
32 VDC or greater; 40 A continuous

Row from the maker’s page: “Breaker (not included)” | “32 VDC or greater, suitable for 40 A continuous NOTE: You can protect the system by using a larger circuit breaker, not to exceed 60 A, if you are operating under high temperatures or if you are sharing the circuit with other devices. You should verify that your boat wiring meets marine wiring standards using a larger breaker before changing it.”

Batteries documented to run this

Every row below is for this trolling motor wired at 24 V. It is also documented at 12 V, and a battery maker’s fitment rule is written per voltage. It turns on the thrust at the voltage the motor is actually wired for, and we hold one thrust figure for this trolling motor — the one at 24 V. So the other configurations are not answered here rather than answered no.

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.

“This product is suitable for 12V trolling motors up to 70lb thrust; 2*identical batteries in series for 24V trolling motors up to 100lb thrust; 3*identical batteries in series for 36V trolling motors up to 120lb thrust.”

Only at 24 volts, and on published figures — neither maker has named the other and nobody has tested this pairing — check yours before buying.

Only within LiTime's ceiling of 100 lb of thrust for a 24 volt motor on two packs in series, and this motor's 56 lb is within it — check yours before buying.

Only within Redodo's ceiling of 100 lb of thrust for a 24 volt motor on two packs in series, and this motor's 56 lb is within it — check yours before buying.

The motor's maker asks for 100 Ah minimum for a lead-acid or AGM battery, and 50 Ah to 100 Ah where the battery is lithium, and a 40 A continuous draw, which the circuit breaker is specified against. This pack is rated 100 Ah and 100 A continuous.

The motor's maker asks for 100 Ah minimum for a lead-acid or AGM battery, and 50 Ah to 100 Ah where the battery is lithium, and a 40 A continuous draw, which the circuit breaker is specified against. This pack is rated 200 Ah and 200 A continuous.

The packs must be identical to each other — the maker's rule says so, and mixing capacities or ages in series is how one cell group ends up carrying the bank.

Which of the two figures applies turns on what is inside this pack, and its chemistry is not published in anything we hold — so the stricter one is used.

The pack's maker permits the series wiring this needs: "Max.

Batteries documented as NOT sufficient

this pack does not reach what the motor's maker asks for: 60 Ah against a floor of 100 Ah

The motor's maker asks for 100 Ah minimum for a lead-acid or AGM battery, and 50 Ah to 100 Ah where the battery is lithium, and a 40 A continuous draw, which the circuit breaker is specified against. This pack is rated 60 Ah and 80 A continuous. Which of the two figures applies turns on what is inside this pack, and its chemistry is not published in anything we hold — so the stricter one is used.
