Bought two ESC70s, installed one and am having issue after issue just trying to set the ESC up, the app either times out ofR just loses connection constantly. Then when I do get it setup and save settings I recheck and it’s defaulted back to factory settings. Then went to run the truck after I thought it was setup right, I go run the truck and it glitches out, stops or just starts to move on its own with no outside input.

Most I am able to do with the app and FD-200 on my iPhone is select my parameters and start the discharge process. Shortly after it disconnects and won’t connect again for the whole process.The discharge process on the FD-200 completes as it should for what it was initially configured. So long as you set end voltage and current, the cycle will automatically end there not draining your packs excessively. This has been an issue for over a year now, that I have seen absolutely no improvements made for it whatsoever. I brought it to the attention of some of the folks at Isdt but they must not have thought it was important. I sincerely hope to see this get fixed soon getting the attention it deserves.

The app is great. Connects to the charger automatically seconds after opening the app and displays the values. It also has a quick refresh rate which is nice to see. I also like the detail that you get on one screen like input voltage, charger temperature, mah, cell voltages, total voltage, charge time and a percentage indicator. My regular (dumb) chargers would make you flip through multiple screens and this just shows everything on one screen. UI is also pleasing to look at and use.

Yes, you read that correct. I tried many devices a year ago to get this stupid device to work. Mine came titled as brand new but someone had opened previously. After this method I am having no disconnecting issues. It was simply an error on the devs programming. I tried my iPhone, SamsungS8 & S2, iPad 11”. Then recently after a year past my OG purchase I tried it on my iPad Pro 3rd gen 12.9 running iOS13.3
