Hello, Recently a BattleBorn tech helped me program a Victron controller and we set the batteries (2 BB 100AH) alarm @ 20 percent 80% discharge not 100%. Evidently if you discharge a lithium ion to 100% there is a whole process to go through to recharge them which I was unaware of. Another tech @ a Victron distributor said the Victron 12/25 smart charger & the Victron smart controller will charge a depleted Lithium ion back to charge without additional equipment & disconnecting batteries. Which would imply different discharge parameters/settings. I feel like it is somewhat of a marketing scheme to state 100% discharge as a selling point. I would really enjoy hearing opinions & clarification on this subject.
