My bank of 4 GEL 220ah batteries has lost its ability to absorb high amp loads through my Victron inverter. This occurs after only a 10% discharge. I have performed a very slow, deep discharge/recharge protocol suggested by my dealer over the winter and this worked for about 30 days but after a period where mainly on shore power the problem reoccurred when on battery only. Is there a fix for this issue.
