bobcoy, very good article everyone should read. I know it is probably best to use a lithium charger on lithiums. I just see it as a "what if" situation arises, and that would be having to use a lead acid when you are out of town and can't get a replacement lithium battery, or in a situation similar. The deal is if you are still using your onboard standard battery charger you can cover all instances of the type battery you may have to use. Even though you may only see 98% charge at certain times the lithium is very up to far more power than a AGM or lead acid would be as they drop full power after a short while of use, around 6 months or so, whereas lithium remains almost full charge. Once you install a full lithium charger you will lose that option. Not intended to be the main factor. As I have stated I have used most of the available chargers we normally see without any issues what so ever. IONIC will soon have their lithium charger available at a sensational cost, light weight and a great configuration for charging. It is certainly worth waiting for. Again we can have choices to what we really need or want at reasonable cost. IONIC is helping make that possible. The Bluetooth App is certainly a great tool for the IONIC user's, very user friendly also. To reprogram a charger profile or not......
