Are you saying a DIY setup with the same functionality as the trollbridge?
Also 12-to-24V converters are common, just get pricey as you get up to high amps.
Think this was it...if not, with more time I'll try to get it as it is easy enough to google....
12 Volt DC 1500 amp Starter relay replaces Delco 1119845 - 9-845 10-D1602.
iI believe the relay is to power a 24 volt load with otherwise 12V charging.
People have reportedly used it for 24V thrusters, lets see if FF chimes in with his experoence and 12/24V relays.
If I really **needed** 24V for my high-amp consumers, I'd go 24V everywhere and use 24-12V converters for low-amp consumer circuits.
Just not practical. Way too expensive to retro.
Absolutely...another test bench excercise/theory versus real world.
there are many ways to skin this cat, some expensive, some less so.
ultimately the existing components determine which new components are necessary...and thus the cost and complication.
Absolutely. AGM are far less robust and shorter lived than top-notch FLA, but some people are bothered by the smell of routine offgassing. AGM do gas but lots less, should not be noticeable as long as they're not sealed up in a box.would gassing be less of an issue with "no maintenance" batteries?

If you're actually interested in investigating further, I'd get in touch with Ann-Marie about the Trollbridge.It's not intuitive to me how one could "partition" a subset of batteries from a combined house bank so they could be combined in some fashion with a relay to power a 24 VDC thruster...and then return them back to their house bank duties. I would seem to me that would be more difficult to achieve than staying with the current setup.
A big Yes to the first, but IMO No to the second.Total cost of ownership is highly likely to be much less than cheap automotive units. You can get decent AGMs at the warehouse clubs and mass merchants.
Only AGM worth buying for that use would be Odyssey, Lifeline or Northstar.
My boat thruster (3Kw Vetus) is powered off the 6 GC deep cycle house bank along with everything else. Uses a total of maybe 30 ft of 2/0 cable. Only one bank to worry about. KISS.
