Review on ⚡️ Iota DLS-55/IQ4 12V 55A 4-Stage Automatic Smart Battery Charger/Power Supply by Mark Taylor

This thing charges at 14.76 volts, which is probably a bit higher for GEL/AGM batteries and normal for flooded batteries, but the problem occurs when it goes into absorption mode and the voltage drops. My other chargers hold the total voltage for a period of time to activate absorption mode and then drop to float. For this, the absorption charge is only 14.16 volts, which is normal for AGM or gel batteries, but too low for flooded ones. batteries. My batteries require 15 volts to absorb and more when they are very cold so this charger will never get them where they should be and will chronically undercharge them if this is my only charger. Chronic undercharging is the number one battery killer. This is the only charger I've seen that has different bulk and sink voltages. My batteries are a USB battery 2200xc in a 2x2 array providing 12v at 470Ah. Mfg's engineering department recommended a 15v state of charge and in my experience Trojans and Duracell also benefit from higher speeds (although not as high as mine where it can reach 15.5v in winter). The disadvantage of higher charge rates is battery corrosion. internal positive postal structure, but that lasts 5+ years (and even then the batteries still last 2-3 years). Chronic Otoh undercharge causes severe sulfation in just 3 years. I live off the grid and this charger is only used during long periods of darkness, usually in the winter when the solar can't keep up - it fills my 2KW solar panel. Maybe I can live with that, but I would never rely on it for all my charging needs. The Promariner is 40 or 60A more expensive but a much better option (all voltages and timers are adjustable). 35 degrees Fahrenheit. The charger delivered 55A for about 3 minutes and slowly dropped to 25A for about 5 more minutes, which is normal, but as the internal voltage rose to the absorption set point, the charge rate dropped to 14.1V and 13A. This too low for flooded batteries and it surprised me.
