For simple applications or when constant power is required to maintain settings on electronics, look to Marinco battery direct connectors. Sold in pairs, the color coded cases open to reveal four male quick connect terminals with corresponding female terminals (included). Terminal plates have been pre-drilled specifically to match positive and negative marine battery terminals. The plastic case snaps closed to protect the terminals from accidental contact and the resulting shorts. Note: we recommend additional circuit protection as required by the manufacturers of connected equipment.
