Maybe they’ll eventually regret it, but our Winnebegan friends left us all alone with the Winnebago EKKO prototype for several hours recently. What happened then is precisely the kind of thing you would expect if you left me alone with an interesting RV. I ran a test!
I just couldn’t resist the opportunity to see exactly how much of a charge one could get from the Balmar alternator in the EKKO, and how much of that could be taken up by the Lithionics batteries. Want to know how much? Watch the video!
The results in the video are pretty self explanatory. We recorded over 120 amps going into the two Lithionics batteries in the EKKO prototype. (And those batteries were charging at 13.5 volts, not 12.) That’s in addition to about 8 amps of running lights and other loads. How does that stack up with the other charging sources in the EKKO? I made this handy graphic to spell it all out.
There is one little bit that I didn’t mention in the video that’s worth noting. In the Lithionics battery monitor app, it gives you the time remaining to either fully charge or fully discharge the batteries (depending on if you’re currently charging or discharging). I don’t know if anyone caught this, but the time remaining to fully charge both batteries – at idle – is about 55 minutes. It would be shorter if you were driving! Interesting stuff! Beyond that, there’s not much else to say that isn’t already in the video.
Yes. The Winnebago EKKO charges at idle. The Balmar alternator seems to put out about 1700 watts, and the Lithionics batteries seem more than capable of taking all that charge in. We’ve been saying this for a while. Now, we have numbers to back it up.
(And yes, I am working on a much more detailed review video. It should be out within the week.)
