The Iota DLS-90 battery charger specs list a maximum single-cycle inrush current of 40A @ 108V. To what extent do I need to consider the max charger inrush current when choosing the output current capability of the generator that will power the charger? Is a 1/60s brownout going to bring a...

I have a 12V bank of Trojan T105s that only gets used sporadically. I'd like to use the Victron charge controller that currently sits on it with a more portable AGM battery, and put the Trojan bank on a trickle charger when I'm not using it. According to Trojan, maximum self-discharge for an...

Can I charge a Trojan T105 battery (actually, I'm talking about 2 T105s in series, but that doesn't matter for this discussion) with a 75A charger without damaging (shortening the lifespan of) the battery? If I call correctly, Trojan says to limit charging current to 12-13% of the Ah rating, but...

Just saw this new evaporative cooler that may be of interest to forum members, since it supposedly only consumes 7.4W in operation. They are only claiming that it will drop the temp 10 degrees in a 160 sq. ft. space, but that's all I need most of the time. It doesn't run on 12VDC, but even if I...
