This is a pretty nice deal on an XTAR VC4 Battery Charger that just hit my desk. This charger has a few nice features that you might want to take a look at if you’re in the market for something new. Comes with a LCD screen which displays charging current, battery voltage, charging capacity. It will identify input power and automatically adjust charging method and charging current from 0.1A to 1.0A and max up to 0.5A*4 / 1.0A*2. The XTAR VC4 Goes through 3 stages of charging (TC-CC-CV) and also has a soft start feature, both will help to prolong your batteries’ life.
