Custom Battery Cables And Battery Wiring Harnesses
Lug cables, high-current connector leads, and compact battery harnesses built around your exact length, gauge, and termination requirements.
MiniProto builds 8 AWG through 4/0 battery cables using tinned copper lugs, SGT, marine tinned, and welding cable options. We also build Anderson SB50, SB120, SB175, SB350, Powerpole PP15-45, PP75, PP120, PP180, and XT series assemblies for prototypes, vehicles, equipment, and battery-powered products.
Why MiniProto
Professional Harnesses Without The Wait
High-Current Build Options
Choose lugged battery cables, connectorized power leads, or mixed battery wiring harnesses with the gauge, jacket, and strain relief your system needs.
Engineer-Reviewed Details
We check connector current, wire gauge, polarity, lug hole size, bend direction, and length callouts before manufacturing.
Prototype Through Small Batch
Order one replacement cable or a repeatable set for low-volume equipment builds without buying more than you need.
Technical Specifications
Connector, Gauge, And Current Guide
Use these common starting points for custom battery cable and power harness requests. Final ratings depend on connector series, wire construction, temperature, and installation.
| Connector | Gauge | Current | Typical Use |
|---|---|---|---|
| Tinned Copper Lugs | 8 AWG to 4/0 | By cable size | Battery links, grounds, bus bars |
| Anderson SB50 | 6 to 10 AWG | Up to 50A typical | Chargers, small EV, equipment power |
| Anderson SB120/SB175 | 1 to 6 AWG | Up to 175A typical | Forklift, robotics, battery packs |
| Anderson SB350 | 1/0 to 4/0 | Up to 350A typical | High-current battery disconnects |
| Powerpole PP15-45/75 | 10 to 20 AWG | 15A to 75A typical | Modular DC distribution |
| Powerpole PP120/180 | 1 to 6 AWG | 120A to 180A typical | Industrial DC power |
| XT30/XT60/XT90 | 8 to 18 AWG | By connector size | Compact LiPo and DC power leads |
We derate recommendations for sustained loads, tight enclosures, elevated temperature, and harness bundling.
Cable And Lug Work
