Charger
See the NOCO GENPRO10X2 connection points and wiring example. Open the diagram in Crimp to add your equipment and plan the cables between them.
Open this example as a new project. Use your own parts and cable lengths to make the plan yours.
Use the diagram as a starting point for your installation. Replace the example equipment and cable lengths with your own, and check the connections against your exact model's instructions.
3 m one way
12 V system
Sized against ABYC E-11. The design current is the unit's rated output. The length is one way; voltage drop includes an equal-length return.
The editable example uses 3.048 m (10 ft) runs unless a shorter run is stated. Metric overviews round these to 3 m. Adapt the parts and lengths to your installation before choosing cable and protection.
This example shows one 10 A charging bank and preserves the supplied 15 A DC lead protection. The second charging bank is independent. The generic drawn cable length is a planning assumption, not the length or a replacement specification for NOCO's supplied leads; follow its extension and connection instructions. Configure each bank for its own battery chemistry. Manufacturer installation manual

Guidance for this model, with sources linked beside the relevant advice.
Verified against the manufacturer's documentation (rev. GENPRO Series NA User Guide 10.30.2024A; GENPRO10X2 column), checked 2026-10-01. Manufacturer documentation →
The GENPRO10X2 specification provides two isolated 12 V banks at 10 A each, not one 20 A output. Each bank has its own mode selection and positive/negative lead pair. The catalog records 20 A total with a 10 A limit on each bank; the cable example shows one bank. The AC supply is 120–240 V, 50–60 Hz; do not connect DC batteries to the AC pins.
Keep each red/black pair with its intended battery. The supplied DC leads are 14 AWG, with 15 A mini-blade fuses; these fuse values are protection, not charging demand. Follow the user guide for the battery/vehicle grounding arrangement, connect the battery leads before AC, and isolate AC before rearranging batteries. Do not join the two bank outputs merely to obtain more current.
Set each bank independently for standard 12 V lead-acid, AGM or lithium. Lithium mode requires a battery with a BMS. Repair mode is for appropriate lead-acid batteries and can expose connected equipment to elevated voltage; remove incompatible loads first. Force mode bypasses normal low-voltage detection and should not be a routine response to an unexplained fault.
Confirm the selected mode, correct polarity, intact inline fuse and sound eyelet connections, then measure battery voltage. The support guide distinguishes standby/low-voltage detection from reverse polarity, excessive voltage and battery failure. IP68 does not remove the need to keep the AC connection safe and dry or to provide a secure, cooled mounting position.
Build it out
Add GENPRO10X2 to your diagram, then connect your batteries, chargers and loads. Crimp calculates cable sizes and checks the connections as you draw.
Every cable you draw there is sized against ABYC E-11, from the same tables as the reference on this page.
Technical reference
Check the model, ratings and connection points against your own unit before choosing installation hardware.
Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.
Catalog connection points, current direction and planning limits. Check the manufacturer's pinout and connector ratings before installation.

Method & provenance
Manufacturer specifications describe the equipment. Crimp calculates cable results from the circuit and assumptions you enter.
From the maker
Manufacturer, model, ratings and which terminal does what come from the catalog. A newer revision, or the nameplate on the unit in your hand, can say something different — when it does, the nameplate wins.
ABYC E-11
Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. The run length and the current above are what drive the result. Crimp doesn't know how warm your space gets; draw the cable inside an engine-bay zone on the canvas and it sizes for the heat.
Next step
Open this example as a new project. Add your equipment and cable lengths, then review the sizing and checks for your setup.
