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.

Fd200 Bluetooth disconnect all the time useless now do not get this discharger

This App used to be excellent for controlling the FD-200 discharger and I loved it. But since the latest iPhone update this App is now completely useless as it can’t hold a stable Bluetooth connection to the FD-200 unit. It starts out fine and then you get the spinning wheel of death. This is a commonly reported issue in all the RC groups, so I wish ISDT would hurry up and address it, PLEASE!

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
