Specification Operating voltage DC 11-8 volts NiCd-MH 1-14 cells Li-ion-polymer 1-5 series Pb 2-12V Charge current 0.1 to 5.0A Cell balancer up to 5 series Li-poly Weight 350g Dimension 130x90x28 mm Micro-processor controlled charger with cell-balancer BC-5 has the individual voltage balancer that is exactly identical with PB-5 for Li-poly battery inside. BC-5 can charge Ni-Cd, Ni-MH and Pb batteries too but it does not have discharge function. Perfect balancing the Lithium batteies It monitors the voltages of each cell during the charge process to equalize the peak voltage. When the 'Balance charge' mode being performed, the balancing adapter should be connected to the balancing tab of battery pack, as well as the charger's charging lead should be connected to the output of battery pack. And also, please pay attention to the polarity of the battery pack's output which goes to the charger's output. If it is reversed, the short-circuit can be happened on the battery pack. Individual cell connectors for various type of Li-poly battery pack BC-5 comes with a set of individual cell connectors to link with various type of Li-poly battery pack. Temperature sensor The processor monitors the temperature of the battery being charged during the process For safety reason, the charger can stop the process at high temperature by your set up Back-light LCD screen You can adjust the brightness of LCD display Robust outer aluminum case High-quality aluminum case is durable and very efficient to cool out the internal heat
