Devices whose figures this pack does not meet
Neither maker names the other. These devices publish a draw this pack’s own maker does not rate it to deliver continuously. That is a comparison of two documents and not a manufacturer’s refusal — check both against your own equipment before deciding anything.
- Minn Kota Terrova 55 lb (54" shaft, wireless remote)Figures compared — they do not meetView device: Minn Kota Terrova 55 lb (54" shaft, wireless remote) →
Minn Kota ask for “at least a 105 amp-hour rating”, in a paragraph about lead-acid: “The motor will operate with any lead acid, deep cycle marine 12-volt battery/batteries. For best results, use a deep cycle, marine battery with at least a 105 amp-hour rating.” This pack is Cylindrical - LiFePO4. For a lithium pack the same maker's thrust-to-capacity table names a different figure for this motor: “55 lb AGM or Lithium 100Ah 2–4 hours Most common setup” Those are two of Minn Kota's own numbers for two different chemistries, and an amp-hour rating does not carry from one to the other, so they are set out here rather than compared. This pack is rated 20 Ah and 20 A continuous.
