What fails first on Canoe batteries (and what we spec instead)

Canoe is a duty cycle, not a keyword. Electric canoe power. If that sentence is still true after you delete the words “military-grade,” we can quote it.

This rail: House banks, Group 24/27/31 drop-ins, small inverters

Typical size: Typical 100–400Ah; parallel for more

What actually fails

  • Weight in the stern changes how the boat sits. Lead is a trim problem as much as an electrical one.
  • Salt on the posts and a locker that never dries — flooded cells die from corrosion, not from “not enough amp-hours on the box.”

How we quote it

  • Specify sealed terminals and a case you can actually rinse. IP-rated hardware is the marine line item, not a logo.
  • Size usable kWh at 80% depth of discharge, not the sticker Ah on a wet cell you would never empty.

12V on this URL

Sensible up to roughly 2 kW continuous inverter load. After that, step up voltage or parallel with thicker cable.

If you delete the voltage, the Canoe constraints above should still make sense. That is the point.

How we quote Canoe work

Electric canoe power If the locker floods, the BMS board is the part that dies first. Ask for conformal coat and sealed glands, not just “marine grade” on a brochure. Voltage overlay on this URL is only there because the equipment rail is real — delete the voltage and the duty-cycle advice should still read as a sentence. Sensible up to roughly 2 kW continuous inverter load. After that, step up voltage or parallel with thicker cable.

Spec note

If the locker floods, the BMS board is the part that dies first. Ask for conformal coat and sealed glands, not just “marine grade” on a brochure.

Questions we actually get

How do I size a Canoe lithium bank?

Watts × hours, then divide by voltage and by 0.8 if you want 80% depth of discharge. Add the worst ambient. That beats any calculator widget.

Can I keep my existing charger?

If it can hold a lithium charge curve (higher absorb, little or no float), maybe. Send the charger model. A lead-acid-only charger is how people cook packs.

What paperwork can you send?

UN38.3 is the usual transport packet. CAGE 93CZ2 and DUNS 109774429 for government bids. Other marks depend on the SKU — we send PDFs we actually have.
