None of these is a statement that the product is safe or unrecalled — only that our searches found nothing. Each regulator’s own search is linked above.

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:

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.

Rhodan Marine 5th Generation GPS Anchor (24, 36 or 48 V)Figures compared
One of these.
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.
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, with a peak of 150A (Max 3 seconds), leaving 50 A of headroom at the motor's hardest moment. 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. 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. Neither company has named the other and nobody has tested the pairing.

Compatible platforms

The motors this pack is documented to run are listed above. No boat, rig or other platform in this catalogue is listed as carrying it — that is a separate question from what it will power, and nothing is listed until a source answers it.
