Efest introduces their LUC V2 charger which can independently charge your individual batteries, and can support two batteries charging at the same time. Manufactured with a digital screen to show precise voltage of the batteries on each port. An auto-detect feature is present to adjust output accordingly depending on battery size. There are four kinds of protection built into this charger which include over-discharging, over-voltage, short circuit, and reverse polarity. The auto-stop function once batteries are fully charged helps protect the cells of each battery it charges. Compatible battery sizes are: 10440, 14500, 14650, 18500, 17670, 18650, 18700, 26500, 26650. Always store in a dry place, DO NOT charge batteries if they show any sign of wear or damage. Never leave charging batteries unattended to prevent any malfunction.
