RUiXU 4AWG Cable 5/16” Lugs + Pluggable Battery Pole Connector

RUiXU 4AWG Cable — 5/16" Lugs + Pluggable Battery Pole Connector

Pure copper 4 AWG battery cable, pre-terminated with a 5/16" lug on one end and a pluggable battery pole connector on the other, supplied as a red and black pair. RUiXU rates it for 48V systems in the 2,000W to 5,000W range, which covers most single-inverter residential builds.

Three lengths are available so you can match the actual distance between your battery and inverter rather than coiling excess cable behind the equipment. Because both ends arrive terminated, there's no crimping to do and no chance of an undersized lug creating a hot connection.

• Pure Copper 4 AWG: Full copper conductor — not copper-clad aluminium — for lower resistance and less heat.
• Rated for 2,000W–5,000W at 48V: RUiXU's recommendation for this gauge on a 48V system.
• 5/16" Lug + Pluggable Connector: One lugged end and one pluggable battery pole connector, ready to install.
• Three Lengths: 30cm, 80cm, and 200cm options so you can match the real distance in your install.
• Supplied as a Pair: Red positive and black negative, so polarity stays unambiguous.
