I believe it is the standard wiring, thank you for explaining about the discharge. To answer your questions:
1. Yes they are both 12v
2. Because I put both on at under 70% and both have charged to 90%
3. I bought the batteries as is. Might have mis-spoke when I talked about wiring there.
4. I have a volt meter that does dc and ac . I also have higher gage wire |
So if you have the standard rpod wiring then the mystery is how did the battery connected to the solar port get charged? Do you have a solar kit connected? If not then it shouldn't be getting charged or discharged, because there should not be anything connected to those wires. Where are you seeing the 90% state of charge reading?
I should have maybe been more clear on the multimeter. Pretty much all multimeters will measure both ac and dc voltage. I was talking about measuring dc current,which is more unusual. That would tell you how much charging and discharging you are getting.
In any case, you have the meter you have. The two smaller gauge wires are the ones that go to the solar port. Assuming there is no solar connected, disconnect them from that battery and measure the dc voltage on them. Should be zero. If so set them aside.
Get two battery cables, one red and one black. Minimum gauge should be 6, 2 gauge or 1/0 is better. Connect + to + and - to - of your two batteries.
Then connect the heavier gauge - cable on the rPod to the - of one battery and the + to the + of the other battery. Verify with your meter first which is + and which is - before connecting. You can plug in the rPod and turn on the charger to be sure, but then shut it down again while connecting.
The reason for attaching + to one battery and - to the other is to better balance current flow between them.
One last question, the standard WFCO charger in the rPod is not designed for lithium batteries. If you overcharge Li batteries you can start a fire. So, you need to be sure that you have a safe system there, either by changing the standard WFCO for a LI charger or being sure that the batteries themselves are internally protected from overcharging.
Also, you will not be able to effectively charge Li batteries from your tow vehicle without additional equipment. There really is a lot to converting a trailer to lithium batts and you need to understand all of that or it will at best be ineffective and at worst can be very dangerous.
