Hi all. Recently reconnected the AGM battery to the yeti 400, upon charging with the power pack via blue tip it displays battery amount as normal. After a while the wattage starts climbing up to just under 60w, then screen goes dark and flashes low watts and then screen starts again like it’s got a weird reboot loop. Anyone else seen this when charging a yeti 400 AGM. Hoping the board hasn’t got issues and just down to low cell voltage.
