Hoping to upgrade to lithium batteries in the not to distant future. The first step is to replace an old dual pro 4 bank charger that has one bad bank. I am interested in anybody’s experience with the ionic chargers. I would initially be using this to charge an AGM starting battery and 3 wet cell trolling batteries. I think the ionic charger can do that as well as lithium’s but not sure. Plan on getting the ionic batteries when I do make the switch. Thanks...
