I bought one recently but this is the first weekend that I did not have work Saturday morning or the sun did not want to cooperate with me but today it is coordinating with me and I run a very simple test on a 12 volt battery pack and it stop charging ar 14.4 volts
Here is the website link where I bought it from

I ran this test with a new 12 volt solar panel that has a no load voltage of 19.0 and an output current of 9.1 amps
I do not remember the starting voltage but the charging amps was 1.4 amps
What I was interested in at what voltage it cut off at was this purpose was
Now the next test is what voltage does it cut off at on 24 volt battery pack
