ISD Go

1. It is impossible to discharge batteries up to 3.0 volts. They always discharge to 3.3 volts. When you change the tension, nothing changes. There is a very lack of the discharge function to a lower voltage to conduct full-fledged battery tests. There is not enough ability to kill batteries by discharging up to 0.0 volts. 2. It is also not enough to set the discharge current of 6,7,8,9 amperes. 3. Constant conflicts of presets and current changes in current and discharge voltage.

После последнего обновления проблемы со связью Bluetooth, постоянно теряется связь . Некорректен отображается уровень заряда в процентах (например вместо 100% отображается 160%) Также добавьте пожалуйста возможность выбирать с 5 ампер до 15 ампер с шагом в 1 ампер а не с шагом в 5 как сейчас.

New version doesn’t work with H605

Lost connect after paring, need delete h605 air and parring again. It helps me for a while.

The font size is too big on iPhone SE, the information just do not fit on screen

What ever you do don’t update the software because you will never connect to the discharger again through Bluetooth. These developers don’t even care to fix the issue. So don’t buy the ISDT FD-200 if your looking for the Bluetooth features.

Doesn't stay connected via BT, more Error messages than anything, not terribly intuitive, timeout messages etc, just a lousy non functioning app all around.

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

I just got the FD-200 and the app will sometimes connect and let you make changes but it always disconnects while discharging. Doesn’t matter where my phone is, next to it on either side, on top, in front or behind it still disconnects.

Using it with an FD200 discharger. The app is useless it disconnects from discharger or does not connect. Also when lucky enough to get it to work the unit keeps discharging batteries regardless of parameters selected on the app. Renders the FD200 useless as it will continue discharging lipo batteries below the point of no return. Shame as it was a functional product before the latest update.
