MPPT 60AMP Solar Charge Controller 12V 24V 36V 48V DC Battery Regulator Testing results on 12 volts

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

cut off is for preventing overcharge?

It depends on what battery chemistry you selected?

14.4V seems like a sealed lead acid (allowing for some equalization) or lithium iron phosphate (full 100% charge). I think the thresholds should be different for lithium iron phosphate versus cobalt or manganese which is not clear in the description, but suspecting it's iron phosphate because there is no really good multiple for the cobalt/manganese cells (4.2x4 is too high and 3.7x3 is too low)

A 24V pack usually means cutoff at 28.8V.
