The ISDT K4 is a dual-channel AC/DC smart battery charger with two independent charging channels. It supports AC input from 100–240V and DC input from 10–34V.
The charger provides up to 400W total charging power when operating from AC input, or up to 600W per channel from a DC power source. Each channel supports charging currents from 0.2–20.0A.
The K4 supports LiFe, Li-Ion and LiPo batteries from 1–8S, LiHV and ULiHV batteries from 1–7S, Pb batteries from 1–14S, and NiMH/NiCd batteries from 1–18S. It also supports parallel charging and is compatible with BattAir smart battery information technology
