Comments about Blue Sea Systems Add-A-Battery Dual Circuit System:

Have to understand that you only get the part. We had to design and install a support board so that we could mount this on the boat. Eeded a "few" other parts (wires cables etc) to complete the installation

                Hello Jeff,

                No. It is not recommended to tie three batteries together with a single switch.

                Thank you,
