All Charged Up And Nowhere to Go

The 24V DC 30Amp battery charger is in place and functional. No real setup. Just wire it in, throw the switch on the AC panel, and push the charger’s “on” button. It just “works”. Can’t complain. Battery charger in “bulk charge” mode on the 245Ah battery bank. Still to be wired: remote battery temperature sensor …

Transplanted Power

As the 24volt electrical system is built out, there is a need, of course, for a 24volt power source. I had a couple old flooded cell batteries of different sizes kicking around, but those ultimately died (I mean dried-up, exposed plate, dead). I tried wiring in a small 24volt DC power supply, similar to the …

Battery Cable Wrap-Up

I chose a house bank electrical configuration and wrapped up the battery connections. This involved fabricating solid copper buss bars and small jumpers made from 2/0 battery cable. I also did the final routing of the house bank battery cables to the main battery box. This involved securing the cables to the bulkheads with the …

Battery Cables… I Don’t Like ‘Em.

No sir. I don’t like ’em. Making battery cables is one of those tasks where the enjoyment of building a boat wears pretty thin after doing it once or twice. It’s just tedious and boring. Dealing with stiff 2/0 size cable is annoying. But it has to be done. Making a battery cable generally goes …

DC Electrical Mains

After finally receiving a couple back ordered parts, I finished assembling the (admittedly overengineered) panel for the main DC terminals and fuses. Always trying to optimize space while keeping things tidy, it *just* fits between two pairs of fuel supply/return hoses for the day tanks. Panels mounted between fuel hose runs Mounted in the right hand panel …

More Batteries!

It has been decided, and executed: the aft-most dinette riser base cabinet will be used to store batteries. As the contents of the cabinet cannot be readily accessed, its storage is best used for occasionally accessed items. It will be used to store two battery banks: Engine Start Bank – the box is big enough for one …

Forward Battery Box

… is IN! Nothing really fancy here. Just your typical marine polypropylene molded battery box. It will hold two 12 volt, Group 27 size starter batteries, to supply the momentary, yet, high current power to the nearby electric bow thruster and electric windlass (both of which will be 24 volt). The location is under the forward …

Temporary Battery Bank (More)

I made up the battery cables and fished them through the conduit. The conduit in the picture is temporary as the riser has not been built yet (still a ways off). The goal is to keep the wire run as short as possible, secure, yet easy to get at should they need replacement.  The battery cables …

Temporary House Battery Bank

I installed some old, used batteries (but still considered good by the battery tester) to act as the primary house bank. This gives me something to work with as the electrical bits are planned/designed/installed. A 24 volt battery bank made from an extra 12v battery from my truck, and two 6 volt golf cart batteries …
