Renogy 1FT 4/0AWG Anderson Adapter Cable (SB350 to Ring Lugs)

This 1-foot adapter cable provides a simple, durable way to add a REGO 12V 400A lithium battery or connect a REGO inverter/charger to your existing system. It pairs a heavy-duty Anderson SB350 connector with ring lugs and uses large 4/0 AWG tinned copper conductors for efficient, high-current power transfer.

Benefits

Save time installing or expanding your system with a ready-to-use plug-and-play cable that reduces wiring complexity.
Rely on stable high-current connections to minimize voltage drop and protect sensitive equipment.
Reduce maintenance and downtime thanks to robust materials and tested connectors that withstand vibration and harsh conditions.
Keep your system working reliably in extreme environments with cable and connector materials rated for wide temperature ranges.
Make upgrades straightforward—connect batteries or inverters without custom fabrication or special tools.

Features

1 ft length for short, direct connections between battery and system components.
4/0 AWG high-purity, oxygen-free tinned copper wire for maximum conductivity.
Anderson SB350 connector on one end for secure, high-current mating.
