Designed to accommodate a wide range of battery sizes, including popular 18650, 20700, 21700 and 26650 cells, the VC4SL can even accommodate protected 21700 batteries. Its four independent charging slots allow multiple batteries to be charged simultaneously, while adjustable charging currents give users greater control over how their batteries are charged.
With a suitable power source, the VC4SL supports charging currents of up to 3A for a single battery, 2A × 2 batteries or 1A × 4 batteries. Users can manually select charging currents from 0.25A to 3A, making it possible to choose between faster charging and lower charging currents depending on the battery and application.
More than simply a charger, the VC4SL also functions as a battery analyser. Its LCD display provides useful battery information, while dedicated testing and storage functions help users evaluate battery capacity and prepare compatible batteries for storage. It can also help revive many over-discharged batteries, making it particularly useful for users who maintain a large collection of rechargeable cells.
