    This charger is absolutely awesome. Everything worked right out of the box and as advertised. The touch screen is responsive, the diagnostics are great, and it takes care of my 18650s and 28650s. I have yet to try it on NiCad batteries though. We'll see on that.

    Yeah, it is expensive; but, I am not sorry that I bought it. It was well worth the $99.00 !

    I world definitely recommend this to anyone looking for a top notch charger.

    Unrivaled for home use management of batteries. I love the capacity feature (see photo) and also the ability to measure the internal impedance.

    Have so far tested the charge capacity of a variety of Li-ion brands and some NiMH cells. Later I will disassemble some old e-bike battery packs to sort out the best cells for re-usability.

    I also learned that 15-20% of each cell's capacity is on the steep curve below the ~3.2V knee voltage point on the discharge curve.

    This explains why e-bike and other applications with managed batteries shutdown to protect cells discharging below ~3.2V to extend cell life but forfeit some capacity.

    The Epoch X4 is intuitive to use and seems well made.

    Picked this up to replace an xtar VP4 plus that's given me nothing but issues. The Epoch has all of the functionality I'm looking for in a charger and is very user friendly. A bit pricey but worth the money in my opinion.
