Look, hydrometer readings -verify- they are a state of charge polygraph. If you test cells and find them full and the controller or coverter is still in absorbsion...
BAD
If the controller or converter drops from absorbsion to float but a hydrometer reading says the batteries are not at full density
BAD
If batteries are presented a uniformly predictable charge regimen every day they are not going to do the Dr Jekyll Mr. Hyde routine. If the charging device can't walk and chew gum, stick behind a rear tire and back the vehicle up a foot or two. That is an effective fix-it tool for schizoid mechanisms.
Once a charging management device is dialed-in it should stay that way for months. Temperature and battery condition will affect the dial-in.
Most charge management devices do not allow to user to dial-in (tweak) charge protocols to suit the battery. The battery gets angry and has the last word.
lol... i already had to send a pm4b 60amp back after it literally blew up on the second use, but i'm hopeful this one won't end up serving as a temporary leveling device!
yes, it would be preferable to have a charger that i could tweak to my batteries' specs... i tend to be rather hands on, anyway. in the meanwhile, i will put the pm4b to the test and see how it performs with my batteries.
the marketing of these so-called "smart" chargers would lead one to believe they are much smarter than a 5th grader, but clearly this is not the case. and thinking now that this is a rather common issue, i believe i'm on the right track to figuring this all out... and thanks for reminding me of the importance of SG testing... i've been rather slack in that area lately.
