Does the 30 amp control module do the current limiting from the lithium battery to lead acid one or does the battery charger?

I just dug a bit deeper into the Blue Sea literature. Some of the switches, like the E series, specifically say make before break so no interruption in power for battery select situations. Others...

Just a note of caution on the solar switching. As we have discussed in the past, you have to be careful about having panel output to the controller and a battery connected. Without the battery, the...

We certainly do have a "throw away" culture here compared to other places in the world, at least from what I have seen. It seems that even stuff that could easily be repaired can't be because the...

That is interesting and probably a good thing for SOC accuracy. If it is totalizing from instantaneous watt readings, those voltages would be independent of any later bounce back voltage, I think,...
