I thought I posted this already…but do not see it
so here goes again…
I bought a BestGo lithium battery. It has a built in BMS with blue tooth. It is great to be able to see what is happening.
so…charged it for the first time ….at 14.0v I got a fault alarm. Battery 4 was showing over-charge
so..I tried this…
I set my MPPT to absorb at 13.99v. The result was that absorb kept charging till it was up 14.1 and the alarm happened.
next I set the MPPT to absorb at 13.99v, but set absorb time to 0. The result was no fault alarm occurred. It dropped to 13.5 till sunset.
this is plenty of capacity for me….with lots to spare.
can I just run like this? It would be 5 weeks before a new battery can reach me any way…maybe I will drive to Salt Lake and get a new one next month ..
meanwhile?
