HRTDK:
Thank you. Might try it. But, sounds like it likely will do nothing, IF the problem is the BMS.
I wrote "converter" as won't charge, but not honestly sure. It did charge the lithium batteries previously, before they went completely dead. When I could still start my genset with the batteries, I tried the PD lithium converter and it seemed to charge a little, but very slowly. Now, since the batteries are not useable, I can't even start the genset without hooking up a cheap Walmart SLA battery I bought instead of the lithiums.
Been wondering about how to wire in the SLA battery so I could start and run the genset through the WFCO power panel and that PD converter to try to charge the lithium batteries that way. Really don't know how to do that. The other option is to go to an RV park and hook up to shore power there to try the converter charge that way. (Ugh.) As a newbie, I really didn't even think of that possible solution until last Friday as I struggled with all of this.
Just John:
Thank you, also.
To your point #2. Interestingly, I have just realized when trying the new/second SCC I purchased, that the SCC reads the batteries as 10.5 volts. If I turn on the PV panels, the controller immediately reads that the batteries are FULL? Is that the BMS causing that? Whatever is causing the controller to read "full," I assume, is the reason the batteries won't charge?
Now, I admit I don't really understand what you are saying the way BMS reset, given the one seller's (very limited) "charge until full and the BMS will reset" instruction.
By the way, again this morning I checked and the lithium batteries read 13.37 volts disconnected from everything using my multimeter. Then, connecting them to the system, the controller reads 9.5V to 9.9V and then settles at 10.5 volts. In a separate, limited post, I asked the question why, how is that possible, and no one was able to explain.
The batteries would only accept a charge from the 120V lithium battery charger that came with them from the manufacturer. It was very slow (10 amp chargers). Then finally, after several days of charging, they apparently hit some sort of maximum and stopped charging any further. One at 13.37V, one at 13.31V and the last at 13.29 V. Won't go any higher. Again, multimeter reading completely disconnected from everything.
And, thank you for that offer. I'm in the Yuma area, but a week or so from departing for various reasons. If there's no progress by then, I might just head your way. I will appreciate another more-knowledgeable-than-me mind on the problem.
FYI, I previously looked at the Rich 40 amp SCC, but bought my second one from Windy Nation (TrakMax 40amp) because they have been so helpful and supportive of me. They look identical, except for the color of the plastic case. Likely the same Chinese manufacturer, although specs could be different.
It seems to me the key is the BMS and getting those to "reset." Since I can't get any help from the eBay seller from whom I bought last year (and the new sellers of the same batteries are not really interested in helping), I'm pretty much dead in the water without that reset.
Thank you again. I'll let you know.
It is very frustrating.
