So you like rechargeable batteries but have discovered the frustrations of unbalanced charging. You also border on the edge of obsession when it comes to batteries and you want the very best for your rechargeable cells. No other battery charger can compare when it comes to the level of control over every aspect of charging and cycling your cells. Also no other charger allows you to log every detail of the entire process including voltage, current, temperature and more. You can plot the voltage of your cells over time to see exactly when charging was terminated or plot a discharge curve to estimate battery health. This latest version allows both logging to an SD card as well as real-time viewing of data from multiple chargers on a connected PC. Of course it can JUST charge batteries, but it can also do so much more. Refresh old cells to help extend their usable life. Analyze batteries to get their actual capacity or break in new cells so they are operating at peak performance. There is also a dedicated forum that you can post questions and make suggestions for future upgrades and models.
