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 love this compact, yet versatile, gadget. It was helpful on a camping trip, providing USB-C power from a lead-acid battery with low-voltage protection. Additionally, it can charge a wide range of battery types as well.

Excellent charger, especially for the price. It's very compact, great for traveling, and can easily be your "daily driver". I've seen some complaints about it not having a discharge feature, but it can be used to discharge your batteries by charging another device. When I need to discharge one of my batteries, I use its USB C port to transfer the charge from my LiPo/LiIon to my laptop, phone, whatever. It as a low voltage protection mechanism so it stops discharging when it reaches a preset voltage.

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 😉

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.

Shuts down by itself screen goes blank tried 2 different changers latest firmware can wake it and it’ll finish charging but this is a gimmick at this point compared to the Q6 nano was hoping to use the Bluetooth functionality well at home charging as well as at the field or the track. We have an idea where my battery packs are at when I’m stepping away from my station just going back to the old nanos

This charger does a lot of things right, but it has some huge (at least for me) issues. The bad: - the PB / lead-acid battery mode, when charging ends, doesn't decrease the voltage. Ideally, I would like to charge the PB battery to 14.6V and then keep it at 13.5V (just like many other PB chargers / maintainers do). This one will keep it at whatever voltage you set at the beginning of the charging, so if you want to use it as battery tender, it would require you to manually set the charging to 13.5V after the charging is completed. - it always limits the input power to 60W for both of my PD chargers despite claiming to be 140W compatible. If I use the PD trigger board (you know, this one that you connect to your charger and "fools" it into delivering other voltages than 5V), and connect to XT input port, my PD charger doesn't have issues delivering 140W of power. (my PD charger will cut power at ~155W). - THE BIGGEST ISSUE IS HOW IT BEHAVES NEAR END OF CHARGE. It will overvoltage the cells. If the cell is almost charged, it will cut power, voltage will drop to something like 4.18V and then it will start charging again, causing overvoltage, and then it cuts power again, and so on. It can't output steady 4.2V if there's very little current draw. DON'T USE FOR VERY SMALL BATTERIES - I tried charging a 1P 300mAh tiny drone battery and the voltage rose to 4.5V even if the limit was set to 4.2V... DANGEROUS! - if I disconnect the battery, output will rise to 5.3V - it doesn't seem to ever terminate charging... which wouldn't be too bad if it could output steady The good: - easy to setup profiles - it will allow to charge without balance leads, useful if trying to charge pack that doesn't have balance leads exposed, like packs that come with built-in BMS / protection - can pick end voltage, so there's no "storage" option but can set charge voltage to 3.7 or 3.8V per cell and let it cook - if you have at least 2P pack and connect just balance lead, it will power on and tell you each cell's voltage just like those tiny testers, really nice - if you connect main battery power first, it can act as power bank and charge your device taking energy from the battery you connected - no storage / discharge option, but power bank mode allows to set voltage limit, so you could potentially charge your phone and discharge the connected pack at the same time I think those are more software issues than hardware, and it supports bluetooth connection so maybe there's a way to fix it / update, but at this point of time, I can't trust this charger and I will be returning it. Too bad because I really like the UI. If it could auto-detect how many cells there are depending on the

If I hadn’t thrown away the packaging I would had returned it. I bought this for the convenience of charging my whoop batteries using USB C PD as the power source. It charges fine but it lacks a built in storage charge mode. I found a way around it by using the app to set a manual charge voltage, this clearly means that device can support storage charging. The manual charge voltage can’t be saved to the device, in fact you can’t even edit the charge programs from the app. If they add storage charge and the ability to edit the charge programs from the app then this would be a 5 star product but until they add those software elements I would look elsewhere.

Very cool little device. Perfect if you already have some PD power supplies. Surprisingly small and portable. You can establish presets with different voltage limits, charging current, etc, so it's easy to use with multiple batteries. As another reviewer said, you can use it for discharging, but only if you charge some other device with it. For example, plug in your phone or laptop and it will drain the LiPo battery to charge the other device.
