I saw that Sleipner Sidepower makes a serial parallel switch box to convert 12v boats to use 24v thrusters.
Their description: "This switch box enables the installation of 24V thrusters in boats with a 12V system. With an additional 12V battery, you supply 24V for the thruster’s operation, while all batteries are charged by your normal 12V system when the thruster is not running. The reliability of this fully automatic system has been proven in hundreds of boats over many years."
"The Side-Power series/parallel switch box have been designed to provide a safe and reliable 24V power for a 24V thruster in a 12V boat.
It has been specially designed and built to accommodate for the high current demands of an elec- tric thruster and are available in two versions, one for the SE170TC and one for the SP240TC.
It is also designed so that there is no need for additional charging devices and connections, the extra battery will be automatically charged by the “original” charge feed in the boat for the stand- ard battery (battery bank) that are being used as “Batt.1”.
There are no need to install 2 special battery banks as one of the boats “standard” banks can be used as Batt.1, preferably the start battery bank as this is “always” full. The start battery bank is also preferred as there are normally no electronics that can be knocked out by a voltage drop or peak caused by all heavy electromtotors such as a thruster."
That might be an interesting solution for those installing the larger thrusters.
Has anyone used one of these?

It seems it takes your 12 volt wiring and charges a 12v battery and on demand converts that to 24v for the thruster/windlass, as opposed to taking your 12v wiring to a converter that charges a 24v battery.
What's the advantage/disadvantage of the two alternatives?
