The YONHAN charger delivers 20A at 12V and 10A at 24V in a 7-stage cycle, with repair mode for old or idle batteries and winter and summer modes that adapt to temperature changes. The large LCD screen shows charge voltage and current, inside temperature and charge percentage. Protections include reverse polarity, overcurrent, overcharge, short circuit and overheating protection, plus a cooling fan, and the specification met is UL. Input is 100 to 240V at 50 to 60Hz with a maximum of 300W, and the spec table lists a 9 hour charge time. Note the contradiction: the notes say the charger is not compatible with lithium batteries, while the title and first bullet list LiFePO4 among the supported types, so plan around the title and bullet support for LiFePO4.
