CrimpCTEK MXS 7.0
12 V smart charger, 7.2 A maximum, for lead-acid batteries from 14–150 Ah (maintenance charging up to 225 Ah). 220–240 VAC input only — no 120 V version. IP65-rated.

A sizing result with its assumptions attached.
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 design current is the unit's rated output. The Crimp engine applies its ordinary continuous-load headroom, voltage-drop budget, terminal clamp, and standard fuse ladder. The 9.8 ft one-way run is a stated reference, not a universal installation prescription.

What belongs around it.
- 19.7 ft total of 13 AWG (2.5 mm²) marine cable
- Four 13 AWG cable lugs matched to the equipment studs
- 10 A fuse and holder on the positive run
- Heat-shrink, strain relief, and terminal boots sized to the cable

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.
