iSDT FD-200 8S Smart LiPo Discharger (25A/200W)
About this part
Control the discharger with a Bluetooth wireless connection and manage your batteries through the compatible App. A colorful LED indicator provides visual current value cell account. Keep visual progress of the discharge by watching the indicators or keep a close eye on the App, either way you are informed and in control. A pure aluminum passive heat sink, aluminum housing and high speed ball shaft fan give this model ideal heat dissipation with greatly improved heat conduction efficiency.

FD 200 Discharger works very well. Had a difficult time trying to discharge part full batteries after race days or test sessions, taking several hours to get down to storage levels with LiPo batteries. FD 200 reduces this to a few minutes for a mix of 2S and 3S batteries, which is great. Initial concerns over the lack of a balancing port proved to be no problem. Cells remain closely balanced during discharge, you can monitor them separately during discharging, then after discharge just put the discharged cells on to storage charging (separate charger), which completes in 2-3 minutes, and includes final balancing as well. Too easy, throw in the blue tooth monitoring and the very compact size, its a great solution, highly recommended. It works fast enough to use for pump-n-dump cycling on race days, which really sparks up the batteries for race use. You must follow all the LiPo regimen when doing this, but it works very well and it seems the batteries love to get a good work out. Make sure it has plenty of clear air space around it, it dissipates a lot of heat very quickly.
ISDT makes great products, this discharger will drain a 5000 6s in 20 mins all while proving accurate information to your phone through BT
It works great. I used the ISD GO app on an iPhone 12 to update the FD-200 to the most current firmware version when I started it. I has maintained a connection to my phone every time that I have used it. It took the discharge time for a fully charged 3200mah 3s battery from over 4 hours using a Spektrum 2100 to under 15 minutes. The power connector is the XT60 format so make sure you get a XT60 to IC3 adapter before you use it to make you life easier.
Discharger works and can take a 7500 4S down in 15 minutes or so. Only issue I have, and it looks like some others is that the app doesn't work with android. Tried 2 phones and a galaxy tablet all with the same results. I can connect via Bluetooth but can't do anything with the app after that. I just wish I knew what end voltage it will stop the discharge. Right now I'm not comfortable walking away from it and leave a cell checker on the balance port. I pulled it at ~3.83 and it was still going... customer support at ISDT seems non-existent.
This thing would be great and 5 stars if the app works. I have a samsung android galaxy s21. I put the FD-200 in pairing mode, paired with the app, it connects, and shows the device but never updates any details.. Tried this 3 times, rebooted my phone, same results Pretty bad experience. Atleast there are physical buttons that still work for "Storage" mode at 3.8v, but now you can't touch the cell voltage settings.
Reviewers agree the FD-200 discharges LiPo packs quickly, with reports of 4S to 8S packs taking roughly 15 to 20 minutes, and that it works without a balance port. Several note it is compact and accurate at reaching storage voltage. The main recurring problem is the companion app: some Android and Samsung users could not pair or control the unit, while an iPad or iPhone worked for others. Reviewers also cite a lack of mAh capacity display, no graphing, the inability to view the app without connected hardware, and noise during operation. One reviewer was uncomfortable leaving it unattended because the end voltage was unclear, and reported weak support responses.
