Howdy,

It seems most posts out there are related to dual battery systems. This post is for single battery solutions.
The idea of a simple, one battery solution is appealing to many. I have a 800 amp battery jump box for backup power.

My 2011 Glastron GT205 came from the factory with one exposed battery, no battery switch,
and all the positive and negative connections directly stacked on top of the exposed battery terminals.

So I did the following.

1. Put the battery in a battery box that covered the terminals
2. Painted and glued a 1X4 to the inside transom using 3M 4200 to avoid putting screw holes in my transom.
3. Installed two Blue Sea 2301 150 Amp busbars on the 1X4 bracket using stainless steel screws and labeled each side.
4. Installed a Blue Sea single battery, single circuit switch on the 1X4 bracket using stainless steel screws.
5. Connected the switch to the positive busbar using 4 gauge, type 3 wire.
6. Connected the switch to the positvie battery terminal using using 4 gauge, type 3 wire with tin plated connectors.
7. Connected the negative busbar to the negative battery terminal using using 4 gauge, type 3 wire with tin plated connectors.
8. Connected the positive starter motor wire directly to the switch.
9. Connected the auto bilge pump circuit directly to the battery.
10. Converted all of the negative and positive connection wires to use #10 ring connectors for the busbar connections.
11. Used color coded, heat shrink insulation on all connections.

So far it's working as planned.

Let me know if I missed something. I'd rather not find out the hard way.

Just have to realize that anything connected to that bus bar needs to be fused right where it leaves the bus bar.

Thanks bruceb58. The current connections have in line fuses on connections from the positive busbar. So, if I add any more connections, will be sure to also add an inline fuse for each positive connection.
