ISDT 608PD Lipo Battery Charger Discharger, PD 140W DC 240W/10A Dual Mode Input, Smart RC Battery Balance Charger for 2~6S Lithium LiHv LiIon Life NiMH Ni-Cd/Pb,with LCD Display,Phone Control

I was looking for a small portable charger that I could use for a variety of LIPO batteries both at home and on the go. This thing meets my needs and exceeds my expectations.Charging:I start by plugging in the balanced connector, then the XT60, and finally plug into my PD capable USB-C 100w power supply. This device has five charging profiles available, of which I set three for charging the batteries I use (2s, 4s, and 6s LiPo) at 0.5a (I'm never in a rush) to 4.20v. When the finish beep sounds, I press the middle button to place the device into standby, then disconnect the battery. The remaining two profiles are configured for 6s and 4s to 3.80v which I use to recharge those batteries to storage level voltage if I'm not going to use them again in the next few days.Discharging:Unfortunately, discharging is not directly supported, but I found a way that works really good for me. The order of operations is important here. I plug in my XT60 connector from my 4s or 6s to the same port that I charge from. This enables the device as a PD charger to charge other USB devices. It usually prompts me for the minimum battery voltage. If it doesn't pop up, I press the middle button to bring it up. I set the minimum voltage to 15.2v for 4s (3.80v x 4) and 22.8v for 6s (3.80v x 6). Then I use it to charge my phone. It will stop charging my phone when the LiPo cells fall to the specified voltage and my batteries are ready for storage. At this point I like to plug in the balanced connector to make sure each cell is close to 3.8c before storing. I like to do this while heading home with any batteries I didn't use up in the day.Also - The free app named "ISD Link" was quick to install, and allows me to update the firmware, view the current status and update thee settings using a pretty ok interface.

Outstanding charger! In the days of USB PD power I am loving this charger! It stores charge profiles, has great metrics and charge status values on screen. I love that it tells you as soon as you plug it in how many watts your USBC power supply (30w, 65w, 100w, etc.) can deliver and safely limits charging to that. Buy 2-3+ of these and some cheap USBC power plugs and USBC cables and you can charge more batteries at a time than you can with the $200-350 2 and 3 port chargers out there, for less than half the price.To those saying it doesn’t have a “storage” mode for batteries… just add a charge profile that charges the battery to 3.7-3.8v (per cell). So for 2S it would be 2 x 3.8 =7.6v for a “storage charge”. You can customize a charge profile's max voltage to work for this (and yes, it will remember it between uses).As far as discharging goes, it’s too small to reasonably dissipate heat - but the R/C vehicle/boat/drone you bought the battery for is perfect for discharging 😉

Got this for 3s lipos for my Mojave grom. Super fast charger definitely recommend!

Failed all of the sudden while charging a 6s 6000mah battery. It beeped about low input voltage from another 6s pack that was fully charged rather quickly into the charge cycle, which surprised me. I thought my battery had gone bad and was about to puff or something. I pulled my battery off and now it wont accept input power to charge, usb c pd power output no longer works and the input xt60 on top does nothing. Powering it with a usb c power brick causes the screen to flash for a moment every 2s or so. It works as a cell checker still i guess.. bit disappointed after only 40 days of owning.

I didn't really need another ISDT charger, but I did at some point try to find a nice PD laptop charger for my car and eventually gave up. The fact that this charger is very compact and can do PD in both directions sold me on this. Planning to keep it in my car and use it as a swiss army knife.It all started out on the wrong foot in my initial tests. A USB-C PD cable from Apple that usually works well just couldn't negotiate a PD session between my Lenovo laptop and this charger. Didn't charge the laptop at all, not even at slow speeds. But then, three other USB-C cables I've tried after that worked just fine.Which bring us to the next random stroke of luck. I power my LiPo chargers from repurposed 19V laptop bricks and 608PD just doesn't seem to want to charge anything at 19V PD when connected to a ~19V power source (that includes my 6s Li-ion packs). It probably makes sense in hindsight given what I understand about how buck/boost converters work. But that's another limitation that wasn't spelled out, so I ended up spending my time to troubleshoot.In the end it did charge my laptop at 65W from a 12V source, so it should work just fine in my car with the right USB-C cable, but definitely not without limitations (still bitter it can only go 5V/3A when doing PD from a 6s pack)

I actually love this charger more than my bigger one and it works off type c
