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.

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.
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 60 A continuous, with a peak of 200A (Max 3 seconds), leaving 10 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'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. Neither company has named the other and nobody has tested the pairing.
