Anybody else have one of these?

Thanks for all the inputs!

Part of the mystery is solved.... discovered this 12v-to-24v converter powers up when a DC circuit breaker on the house battery labeled SAT TV/Phone is switched on....

Not sure yet where the output physically connects to that old system, but now I'm wondering if I can possibly repurpose the 24v output to 'trickle charge' the thruster battery bank while underway.... the shorepower charger for that battery bank is a whopping 60 amps at 24 volts.... so this little box outputing 6A at 24 volts.... pretty small stuff huh.

Seems like I would need some sort of regulator to throttle back that trickle charge when the bank is happy wouldn't I? Also -- can 2 chargers be connected? if one is not 'on' and the other 'is' -- will the active one fry the inactive one? and vice versa? etc etc -- need a smart electrician here! Any ideas?

Thanks again

Need to know what the output voltage is exactly. If it's 24V, then it's not going to do much charging unless the thruster battery is pretty much totally dead, and it would never charge it to full.

If the dc-to-dc converter has an adjustable output, you could change it to something like 26.4 to 27.8 VDC and then it would charge the thruster battery fully. and there would be no current flowing once the battery reached its full charge. However, if the thruster battery was fully depleted, then you might pop the output breaker or fuse on the dc-to-dc converter because the battery would absorb more current that the converter is rated to put out, and it might be protected by a fuse to prevent overload.

To answer the last question you'd need to know more about the final circuits in the DC-to-DC converter.
