Check connections if not able to charge 100%

Hello all,
I thought I would pass this along as I am sure I am not the only one to experience this.
My LiFePo4 batteries would only charge to 13.5 volts / 99% and they were stuck there in bulk charge mode for 24 hours. I did a little digging and discovered that one of the cables on the negative bus bar was a bit loose. Not horrible but mobile. Once I tightened that up, the batteries went right up to 14.4 / 100% and dropped out of bulk charge mode. So simple. Just a few road trips were enough to loosen them up. So check them regularly.
A big shout-out to LiTime support. Although I am sure it was AI, they got back to me in minutes with the correct guidance and all is good now.

    Good point to remember, @descott12.  Thanks for sharing!  Sometimes, it is the simplest issue (like a loose wire) that creates headaches.  I just saw a very similar situation resolved the same way today on the iRV2 forum (i.e., tightening a loose wire connected to the battery monitoring system of a motorhome.)
