Super fast startup (1 second)
Auto detecting lipo cells (Auto detection of cell count)
Light and Small size
Bright 2.4" IPS display makes operation clear and simple.
Built in fan
Internal cell resistance calculation
Minimum input voltage settings - super useful if you charge batteries of a bigger Lipo in field (to protect it from over-discharge)
Safety features: internal resistance detection, short circuit protection, over load protection, over voltage protection, over temperature protection, over current protection
I can't really find any. Did not find any bugs or issues in usage so far.
