Hard to decipher how it works for reset calibration and setting current for indicator light, or what it is. Without an auto reset function and proper float transition amps settings, you can't do just one calibration and then be good forever. Amp hours in don't equal amp hours out because of charge efficiency. That's for lead acid, lithium needs different settings for fully charged, usually voltage trigger.
