That's why The Borg was built or more accurately - is being built. AGM batteries do not appreciate 50-90% recharges.
Not knowing what is going on inside an AGM, was voiced by me on this forum several years ago. Deducing voltage and amperage (incidental and hours) trends and tendencies is critical. Most AGM battery owners do not subject their units to repeated long-term 50-90% cycling. Some lightweight users will jeer "My AGM does not require all that babying". Be aware of why that is an answer containing a falsehood within a truth.
