Hitec X4 AC Pro

Blue tooth stopped working on both mine and my buddy's Hitec X4 AC Pro chargers so they all must have a big problem. He has I-phone and I have android and neither will connect. Great idea if it just worked.

Works just as it should. Much easier than using the charger itself. In fact, I haven't touched the charger buttons more than a few times. Only thing I find annoying is, when I'm finished using the charger, it turns my phones Bluetooth off. Not sure if it's just my phone or if it's the app doing it. Otherwise no complaints at all!

I love technology when it just works and that's exactly what this app does. It is such a time-saver for the battery nerds out there and I'm definitely one of them there's nothing like the power just to do a quick glance and see how individual cells are doing. One feature I would like to see on the app especially is internal resistance for each cell built into the app. There is room right next to the individual cell gauges at the bottom right side. To get to the menu to view using the charger is inconvenient and not very easy to understand for the beginner or the intermediate. Overall fantastic charger plenty of power for any kind of multi-rotor or any other RC hobby enthusiasts. I give this one a Big 5 stars for ingenuity and convenience.

Useless you have to be with in 8' of the charger for the app to connect I have try with different devices and the results are the same.

Easy to use and program. I like the graphics that represent charge status. I have programmed multiple battery types into the App for easy charge selection.
