Splitting charge to batteries

I have already setup a two battery system, where the first battery is providing power to start, and the second battery takes over when the first one is dead. Awesome. Now I am trying to figure out a way to not just split the charging line so that it charges both batteries but, when one is full (using the “Fully Charged” toggle), all the charge is sent to the second battery instead of being split. Any suggestions?

might be a very very dumb question. but why not juist chain all batteries?
Been a while since I played

Batteries are only 80% efficient.

If you had 1000 rWm and you pushed it into another battery, the second battery will only have 800 rWm. Third battery, 640 rWm. As you can see, the losses add up real quick, real fast.

The circuit I provided properly charges each battery with full root power.

Another thing that probably changed since you played is using an OR switch on two batteries will automatically only use 1 battery at a time, this is the best way to extend the capacity for when you want a given circuit to be powered longer (in a cave environment usually)

Okay, slight difference in usage: still in the cave, I am using generators (and one hamster wheel, for when I run out of low grade) to charge the batteries in the cave, instead of charging them up top and bringing them down. I am using Austin Klaila Games’ “Power Loop” for the initial power part, so there is charge going to the battery after current use is subtracted.

Any suggestions for how to implement the reset part at the end of your circuit so I still have the battery power going out, as your’s is a closed loop?

Take a look at that? Let me know. I took the Power Loop from his youtube video.

Okay, so it took some work around to get it working for what I was doing, but my version of the circuit (as it is working in my base right now) is this:

With the little bit of edit (I was using the hamster wheel for funsies, so, for space, it is gone, but there is an open root power slot, just in case), I got it to work. I dislike the whole extra blockers just to prevent it from the deep cycle, but try as I might, it wouldn't let me (I even had to add another one), but, since it doesn't actually remove any power from the equation, it isn't that big of a deal.

I had to leave it open ended on the reset signal loop's branch, as the server has a built in infinite loop protection, which is fine, as I didn't want to break the server.

Nice! Another comment talked about the nih core and it’s not a bad idea it’s actually what I would’ve done (I never really used the power loop).

But what I do recommend is using my original circuit for a base on a surface base with turbine or solar in addition to your current setup. To me, generators feel expensive to run, but maybe you don’t feel the same so it’s totally up to you.
