I’ve 16 of same battery packs, and I also additionally practiced some of precisely what you may be describing with unequal battery-charging.
With mine, i understand that they are sulfated to different qualifications, so provides brought about a number of the imbalanced asking voltages. I purchased my personal Lifelines at the lowest terms as „NEW“, nonetheless had seated for a long period and happened to be significantly discharged before I ever have them. I additionally wound up place my cost voltages at the lower end of Lifeline’s guidelines, so I wouldn’t overcharge some of the battery packs.
Functions OK for an emergency support battery system this is certainly seldom neeed, but they are not the things I’d like to depend on for daily off grid living. Some day, i really hope getting a new pair of battery packs acquire to the best beginning (and just take very good care of all of them).
Re: 48 Volt electric battery financial wiring
Let me reveal Edward’s „keyturbocars“ thread where he did a number of analysis and testing a create to recoup Lifeline AGM battery packs:
In the event that electric batteries in series (and parallel) become awfully mismatched (in other words., good power supply https://besthookupwebsites.net/nl/romancetale-overzicht/ in show with sulphated power) may cause the unbalanced charging where one power try charging you at „low current“ therefore the additional at „high current“.
Charging/recovering electric batteries individually may help. Furthermore coordinating electric batteries by capacity („high“ capacity in a single sequence, „low“ capacity in an additional collection sequence) may help too.
