This is the 4 bay Efest Luc V4 smart charger. Efest Luc chargers are known for their quality. The V4 offers 4 independently controlled charging bays, and the ability to select your charging current. Choose between .5 Amps, or 1 Amp for up to four batteries, and 2 Amps a piece if charging only 2. These are selectable modes via the front button. The pertinent charging information for each bay is prominently and clearly displayed on the screen. My Take: You can't go wrong with this charger. If you're looking for more than two bays, this is sure to keep your happy.
