Super Cloud 12AWG(4mm²) 1 Pair Black + Red Solar Panel Extension Cable Wire Plug-in Connector with 6MM Tin Plated Terminals,Plug-in Connector Solar Adaptor Cable (3 FT)

Perfect length for connecting to the battery in the battery box on my travel trailer. Rated a 4 star as I had to replace the ring terminals with a larger size to fit on the deep cycle battery terminals. Everything else plugged in perfectly and performed as expected.

the connectors were backwards, but worked out for me.
