hello, having a smartshunt on the net, what is the best method to calculate the absorption time? I have 178ah of AGM. Is it better for the various Chargers to have adaptive absorption? Or is it better to set a very long fixed time and a tail current (sent to all chargers by the smartshunt) of 1.8% of the capacity? So 3.2A. I have seen some problems with adaptive absorption. 1) if the batteries are at 12.6v at the start of the charge, the absorption lasts 1 hour and is too little for AGM batteries discharged at 80% soc. 2) if absorption has been completed during the day and the batteries discharge slightly during the day, the charge cycle restarts but absorption lasts 1 second.. and in my opinion this is not correct. This defect does not occur with the non-adaptive tail current method. My doubt is: Is a tail current correctly set and sent by the smartshunt always a correct method to end the absorption phase? Even at different depths of discharge?
