      I'm not sure what we're debating here. If you're trying to dispute my claim that batteries won't stay at 100% float then I'm going to...

      No snark taken. I'm throwing it out to try to show where voltages can become seriously disconnected from SoC. If you start cycling to...

      Sure, if you discharge at a slow constant rate this holds true. But throw in a high discharge event and it goes out the window. Try...

      Right. Sure, a blown engine is a big expense, but if you're a member of the club of boat ownership it shouldn't mean financial ruin. I...

      This has been a good discussion. Now we just need to hear how Kevin has made out with his Zeus….

      Yeah, I don't try to beat it. Some things you just live with. If I'm aboard and have appropriate alerts/alarms in place I can live...

      Jeff F replied to the thread Anchor for a rocky bottom.
      Fair enough. But I'd suggest a Fortress is a great #2 anchor, especially if Bruce is #1. Note that it's a *lot* easier to stow away...

      I buy this. Here are my disagreements, based on having used this approach with my alternator regulation. 1) the battery may drift out...
    • Jeff F
      My example may be a bit too contrived. In your use case described above if you held that 100a load for an hour instead of a few minutes...

      I'll offer a prediction here. I think that each discharge cycle draws down the voltage a little bit. Bringing the battery back to 13.5...
    • Jeff F
      Yes, I'd agree with that observation. That's why I think the absorb phase matters. The farther/faster you force a voltage change, the...

      Just beware that once you know the boat really well you'll start noticing things that you really don't like, and recognizing...

      One more anecdote that's closer to home. When I installed Lithium 3.5 years ago I deliberately wanted to rely on solar as much as...
    • Jeff F
      Approach this as a calibration challenge. I'd posit that since you've never tried significantly higher thresholds (not just voltage...
    • Jeff F
      Right. By using 13.8 you're leaving ~10% of capacity on the table. If you were more aggressive with the top charge you'd never see...
