How the 300Ah LFP is wired
The run drawn here is the reference topology for this part. Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. Confirm your own run length, routing and terminations before ordering — open this part in the designer to size it against your actual system.
What size cable and fuse does the 300Ah LFP need?
There is no standalone feed to size here: this part either has no positive current-carrying terminal or declares no continuous draw or rated output of its own, so a lone cable number would really be its terminal rating. Its cables are sized by the circuits they serve — use the terminal map and the complete-system fit check.

Start from this part
Open the canvas with the 300Ah LFP already placed, then wire the rest of the system around it. Nothing to install and no sign-up — the project is saved in this browser, and you can download the file whenever you want it.

Catalog profile
The manufacturer, model, ratings and terminal map are maintained as planning data in Crimp's component catalog. Confirm the current manufacturer manual, exact revision and installed nameplate before ordering or wiring.
Engine reference
Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The published conductor, fuse and voltage-drop result uses the visible reference length and current basis; it is not a universal installation prescription.
