The Garmin Force (20–45 V, 50" and 57" shafts) is a trolling motor with a peak draw of 57 A, a continuous draw of 60 A, a stated minimum of 100 Ah for lead-acid or AGM and a recommended 50–100 Ah.
Last updated: 16 September 2026
What we found
- 17 battery models are matched as running it across 5 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.
- 3 batteries are explicitly documented as NOT suitable for it: Dakota Lithium 12V 54Ah, Dakota Lithium 12V 46Ah Deep Cycle U1, Renogy 12V 20Ah Deep Cycle.
- Published as 57 A at full throttle on a 24 V bank · 100 lbf at full throttle on a 36 V bank.
- 23 specifications are published for it, each with the source it was read from.
Assembled from the evidence on this page. Every figure and count below is shown with the source it was read from.
At a glance
The maker’s own installation requirements: 42 VDC or greater, suitable for 60 A continuous (not to exceed 90 A). A battery that meets the draw does not make the wiring optional.

“Garmin has received a small number of reports indicating the Force Trolling Motor may move the boat unexpectedly and quickly when the anchor lock feature is engaged This can be caused by 1) the coil cable being tightly compressed between the steering housing and the shaft cap, or 2) the motor shaft being out of alignment.”
Source: www8.garmin.com/marine/notices/Force_Trolling_Motor_Service_Alert_June_2020.pdf
“You must disconnect the motor from the battery before servicing the trolling motor to avoid causing an electrical short. When stowing or deploying the motor and when working on the power-cable terminals, be aware of the risk of entrapment or pinching from moving parts, which can result in injury.”

“Garmin has determined the nuts on the power terminals of the trolling motor may not be fully tightened. In certain situations, this can cause heat to build up on the power cable, which could lead to a brief electrical fire on the wire insulation. As mandated in the Force Trolling Motor Installation Instructions, you must install a proper circuit breaker, which can limit heat buildup after the breaker trips. It should also be noted that the wire insulation is flame retardant and self-extinguishing. These factors help limit the scope and duration of any potential brief electrical fire.”

“In certain rare situations, especially during or after use in salt water, water may enter the cable-junction box and could lead to a brief electrical fire.

Batteries documented to run this
Every row below is for this trolling motor wired at 36 V. It is also documented at 24 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. We hold one thrust figure for this trolling motor and it is the one at 36 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:
- A motor’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 manufacturer or a dealer before buying.
