SB50 DC Power Cable
One cable. Hundreds of possibilities. Whether you're wiring a DC-DC charger, building a portable battery box, adding a trailer quick-disconnect, or extending your solar panels, this professionally assembled SB50 DC Power Cable gives you maximum flexibility without needing to crimp your own SB50 contacts.
Every cable is supplied as a complete SB50-to-SB50 cable assembly with professionally installed connectors on both ends. Leave it exactly as it arrives for a ready-to-use extension cable, or simply cut it anywhere along its length to create two custom SB50 connector leads for your own project.
Unlike fixed-length pigtails, every SB50 DC Power Cable ships as one complete cable with connectors installed on both ends. Use it as an extension cable today, or cut it wherever your installation requires to create two custom-length SB50 connector leads. You're free to decide during installation.

Need two SB50 pigtails instead of one long cable? Simply cut the cable anywhere along its length to create two professionally terminated SB50 connector leads. Make each side exactly the length your installation requires instead of being limited to fixed-length pigtails.
Extend Your Solar Panels
This cable also makes an excellent SB50 solar extension cable. Position your folding or portable solar panels in full sun while keeping your battery, power station, or charge controller safely in the shade.
It's fully compatible with the SB50 battery cable supplied with our Sapphire 200W Folding Solar Panel Kit.
Voltage drop depends on the total cable length between your equipment—not just the extension itself. If you're planning longer runs or higher-current applications, choosing 8 AWG or 6 AWG will help reduce voltage drop and maximize charging performance.

Frequently Asked Questions
Does this cable come with open wire ends?
No. Every cable ships as one complete SB50 cable assembly with professionally installed connectors on both ends.
This gives you the greatest flexibility. Leave it intact as an extension cable, or cut it anywhere along its length to create two custom SB50 connector leads exactly the length your project requires.
Can I cut the cable to make two connector leads?
Absolutely. That's one of the biggest advantages of this product. Simply cut the cable wherever your installation requires and you'll have two SB50 connector leads ready to terminate into your equipment.
Can I use this as a solar extension cable?
Yes. Leave the cable intact and it works as a ready-to-use SB50 extension cable for portable solar panels, battery systems, and charge controllers. It's also compatible with the Sapphire 200W Folding Solar Panel Kit.
How do I choose between 10 AWG, 8 AWG, and 6 AWG?
Heavier cable reduces voltage drop and is recommended for longer cable runs or higher current applications. If you're unsure which cable size is best for your installation, contact us and we'll be happy to help.
Can I connect multiple cables together?
Yes. Multiple SB50 DC Power Cables can be connected together to create longer runs. Remember to consider the total cable length and select an appropriate cable size to minimize voltage drop.
