ISDT Smart Lipo Battery Charger,P30 1000W x 2 30A x 2 Dual Channel Bluetooth Lipo Battery Balance Charger Discharger,RC Fast Charger for 1-8S Li-Ion NiCd NiMH LiHV PB Battery

Ive been using this for 18 months. So far it's been charging my Lipo's fine, but the Bluetooth access is failing.Initially I used a Samsung S10 to connect which worked. But 6 months ago I upgraded to a S24 Ultra. Since then the Bluetooth fails to connect.Many others have reported this issue with the ISD GO app. To date the developer hasn't responded to anyone and the issue still is not fixed in the latest version.I bought this charger specifically because it had Bluetooth, which was good when it worked. Now I can only use it via the control panel, which is clunky and not easy to use.Won't be buying ISDT products anyone if this is their 'customer care' policy. Rather 'customer don't care'.

Great charger and delighted with it untill it asked for a firmware update. Never update using your attached mobile phone as it takes around 9 mins to complete and during this proccess it could hang as mine did making the unit useless. Always us a PC with an attached USB cable to update.
