All devices execution A and B have special charging programs for classic lead-acid batteries (also gel or AGM) as well as modern Lithium-LiFePO4 batteries. Please note, that charging of modern Lithium batteries with devices which are used for ordinary batteries in lead-acid-technology (incl. Gel or AGM) will cause probably, that the advantages of this new technology (capacity, number or cycles etc.) is not fully usable. For optimal charging of Lithium-LiFePO4 batteries, we recommend the use of a charge regulator in MPP technology.
