PT Battery Banks

[worktohobby]

Hi all,

Keep in mind that boats have two banks to absolutely guarentee
cranking power when out at sea.

Generally, we can always use the generator if our large single bank
gets too low. Or call a roadside service. A modern battery combiner
will do away with the genset battery not recieving a propper charge
in a PT.

The deaper our batteries are discharged the sooner they fail;
discharge always means chemical imballance and battery dammage. This
is a non-linear relationship. So if we make our main bank smaller, so
that we can have seporate starting batteries, that main bank will now
not last as long; both from a boon docking stand point or long term
battery life.

If you really need starting batteries, you should probably add
seporate batteries for that purpose. If you want to get the most out
of your batteries, you have to monitor them closely.
