Rhodan Marine 5th Generation GPS Anchor (24, 36 or 48 V)

At a glance

That is a peak, not a continuous rating. The maker publishes no continuous draw for this — see below for what they say about it — so a pack sized on the figure above is sized for the worst moment rather than for the load it will hold.

The maker’s own installation requirements: 60 Amps recommended. A battery that meets the draw does not make the wiring optional.

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 48 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 36 V. So the other configurations are not answered here rather than answered no.

Rhodan state this system runs on 24, 36 or 48 volts depending on the model, and that its "system current draw will vary with thrust level up to a maximum of 50 amps at 100% thrust".

This pack is 51.2 V nominal — what the industry sells as 48 volts — and its maker rate it at 100 A continuous as a maximum, and 45 A as their recommendation — so the motor's 50 amps is comfortably inside what the pack can do and 5 A above what its maker suggests for continuous use.

The two figures are different kinds of number: Rhodan's is a peak draw and the pack's is a continuous rating, so the comparison runs the cautious way round.

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

  One of these.

  Only on the 48 volt model, and on published figures — InSight Series 48V 30Ah GC2 Lithium Battery is rated 100 A continuous and Rhodan rate this motor at up to 50 A — check yours before buying.

  Rhodan also ask for a 60 amp breaker. The gap between RELiON's two figures is more than double, so which one a reader is shown changes the answer: against the maximum the motor draws half, and against the recommendation it is over. Rhodan's own display shows "THRUSTER CURRENT DRAW (Amps)" while the boat is running, so this is a figure an owner can watch rather than a calculation.

  Only on the 48 volt model, and on published figures — InSight Series 48V 30Ah Low Temperature Lithium Battery is rated 100 A continuous and Rhodan rate this motor at up to 50 A — check yours before buying.

  Rhodan also ask for a 60 amp breaker. What separates this pack from the GC2 is temperature and nothing else: it takes charge down to -20°C and heats itself below freezing, where the GC2 refuses charge at 0°C. On a boat left on the water through a northern winter that is the whole difference. Rhodan's display shows the live current draw, so RELiON's 45 A recommendation is something an owner can watch themselves against.

  One of these.

  Only on the 48 volt model, and on published figures — EAGLE 2 48V 32Ah is rated 60 A continuous and Rhodan rate this motor at up to 50 A — check yours before buying.

  This pack is 51.2 V nominal — what the industry sells as 48 volts — and its maker rate it at 60 A continuous, with a peak of 200A (Max 3 seconds), leaving 10 A of headroom at the motor's hardest moment. Rhodan also ask for a 60 amp breaker. BigBattery's 60 amps continuous is also exactly the breaker rating Rhodan ask for, at 60 amps. The two figures come from different companies and neither was set with the other in mind, so the agreement is a coincidence worth noticing rather than a design pairing.

  Only on the 48 volt model, and on published figures — HUSKY 2 48V 100Ah (INV) is rated 100 A continuous and Rhodan rate this motor at up to 50 A — check yours before buying.

  This pack is 51.2 V nominal — what the industry sells as 48 volts — and its maker rate it at 100 A continuous, with a peak of 150A (Max 3 seconds), leaving 50 A of headroom at the motor's hardest moment. Rhodan also ask for a 60 amp breaker. BigBattery sell this one for inverter and off-grid work rather than for a boat, and it is a 5.12 kWh bank rather than a trolling-motor pack. The electrical comparison holds regardless — the pack states what it can supply and the motor states what it draws — but what it is sold for is a fact about it a reader should have.
