The Q6 and T8 are two new LiPo battery chargers from ISDT. Q6 packs 300 watts into an unbelievably tiny package. T8 delivers 1000 watts for when you need MOAR POWAH. Both of them are incredibly feature-rich and value-priced.
But there's a catch.
The 300 watt and 1000 watt rating of the chargers is based on charging at the maximum possible voltage (6S for the Q6, 8S for the T8). This inflates the specification a bit if you're actually charging 4S or lower, as most of us are. So if you're looking for the best LiPo charger, you should probably look at the amp rating (14 amps for the Q6 and 30 amps for the T8) not the watt rating.
Even taking this into account, I think these are some of the best value for the money you can buy today.

Joshua - I just started using ISDT and I'm sold. Thanks for covering it and explaining a thing or two about chargers that I didn't know. Yes, I always learn something!
I love my Q6 Plus. So much, I ended up getting 3 of them and I just charge them up individually. No more parallel charging. Just pop 'em in and go. I'll add a few more to m collection. I put a couple in my pack for friends to use as well when we're out in the field.
I have a modded laptop charger that I use for them at home, no issues. You can even find rebranded laptop chargers (new) for like ten bucks or so (talk about recycling New Old Stock!?).
I love the ISDT chargers.
I was thinking of getting the T8 for my home charger so I started researching every battery charger under $100 bucks I could find to see if there was anything better. What I ended up purchasing was the Revolectrix GT 500 ($80 from the Revo USA site) and I love it. It does 500W 20A up to 8S,internal discharge up to 8A or regenerative discharge up to 20A. Sure the T8 is more powerful but 500W is enough for my mini quad lipos. It has a jog wheel and the amount of settings you can play with is crazy! It's also firmware up-gradable with just a regular usb mini cable. After updating the FW it added even more settings. One of my favorites is parallel mode. You just input the mah of one battery times how many you are charging. I had been using cheaper chargers and never realized how much better a higher quality charger could be.
The beginning of this video was a roller-coaster ride of battery charger emotions. I loved it.
Thanks for all your uploads Joshua, you are the yoda of the drone world lol, could you do a video on your power supply for the isdt charger??
Here's the parts list: www.fpvknowitall.com/best-12v-power-supply-parts-list
Here's a video showing it off: ruclips.net/video/KujxQLQeabY/видео.html
Thank you !
Get 30/32V power supply. Your chargers will heat up less, last longer and you'll be able to use their full power.
Own an Icharger 406 and a Q6. The Icharger really is the best charger ever. Combined 75 amps of raw power but the price point is insane. The Q6 is a great fieldcharger. I power it up with a 6S 12000 mah lipo and it keeps me going on a day of flying. For discharge or storage it is a pain in the ass. Discharge max is 0.4 amp so it is taking for ever if it does not overheat before that. So ideal field charger. That T8 looks like an awesome value for money home charger.
Nice THANKS For all your videos on Beta & Cleanflight I am learning something every time I watch .
I have the iSDT Q6 Pro charger, I have used the duel port HiTec for years. I prefer the Q6. I like both chargers. The Q6 is so small and light so I find myself using this charger more. Plus I like the features of the Q6 better and feed back it gives me while charging. The Q6 was like $50 bucks? My HiTec was around $180-$200. I’d recommend the Q6 for sure. I use an old computer power supply to power the Q6, usually charge around 3 amps off the laptop power supply. But being mobile I charge off my Truck at 5.2 Amps. Don’t charge 5 Amps off your cigarette lighter power supply, you have to run designated wires from the battery through the firewall of your vehicle because the cigarette lighter power supply will melt in time charging at 5 amps.
I had this charger for about 8 months. It's definitely got some quirks and reliability issues. For example, I've had to manually calibrate the ports. The individual port readings drifted so far that they no longer added up to the main port's reading. This causes the Q6 to throw an error in the middle of charge.
The other issue is it would spend too much time trying to hit balanced charge. A firmware update seemed to have helped, but recently it's started to really fail to balance charge port #4 completely. It started off as a 5mV offset from other ports and has grown to almost 50~100mV. The self check fails with error code 407-10.
Unfortunately when I contacted ISDT for warranty, they needed me to ship the unit to Shenzhen, China (at my cost). And I'd have to pay shipping for the repaired unit. So to repair a $50 device under warranty, I have to dish out almost $30-40 in shipping.
So at the very least, I recommend buying this from a US distributor like getfpv or Aloft. They have potentially very good service. But I didn't get it from these companies so I'm out of luck.
But to be honest, given the risk of damaging expensive racing lipos (a decent 1500mAh Lipo is like $30), what's the true cost of a defect? ISDT doesn't compensate you if their defective product damages your batteries.
John Xia Yeah I want to buy a T8 but I heard to many bad things. I think I’ll stick with the 20amp icharger
I have the T8 and love it. JB its 35A max input current 30A max out
Thanks Joshua I appreciate your take and presentation. Always so well done.
Very nice video!Thanks for your support to ISDT
I have been using a Thunder AC6 charger for some time now and have wanted to upgrade to a better one. The IChargers look great with some great features, but I have not wanted to spend that amount of money on a single charger. These seem to be a great balance in price and features and I will be picking one up on your recommendation good Sir. Thank you as always for your help and honest reviews, Please keep up the good work.
Bought a Q6 to charge LiHv tiny whoop batteries when they 1st came out, which was last Dec or so if I recall. At the the time there were some growing pains reported on RCG, but mine has been flawless. At least a thousand cycles on it (it does keep track but I don't pay attention) and it's still terrific. I had 2 brand new 4 buttons (Thunder AC680) and they've been almost totally forgotten. (still good chargers, but the Q6 just works so nice).
I routinely charge 6 Graphene 4S1300 and have never needed more even for my Big 6S8000 airplane packs. 300w is enough, but you'll want a 24v supply to get it without hitting the current limit. I built my Q6 into a case with a 24v 280w SMPS and it's a good combo. The Q6 doesn't get by well charging from a car battery, it runs afoul of the low voltage shutdown. I built a 6S10p 18650 pack from surplus cells to use for field power, and it's a great combo.
Thanks for another great review.
Happy Halloween! I love my ISDT Q6. I have been saving up for a Icharger, but the new isdt is so tempting. Thanks for the video.
I use an 150W iSDT SC-608 with a cheap 24V power supply and it has been a fantastic first charger.
I have a 12V lead in the back of the truck for field charging. I use it as a checker too.
I bought the small SC-608 recently as a companion to my awesome Q6 Plus I've been using for a while. I didn't realize it didn't have the Cell Voltage selection in the Storage function as it does in the Q6 and other ISDT chargers. Sometimes I don't always want to store a lipo at 3.80v either which the Q6 allows for. Still, they are great chargers all around in price, features, performance and portability. I really want to pick up a D2 if I see a good price on one.
I’ve been using the Q6 for 6 months and it’s been superb. It can really do the amps it claims. However.. it sucks at discharging, it discharges very slowly and usually after 1 minute it shuts down and says “OMG IM OVERHEATING” and beeps like crazy till you deal with it. Apart from that though, I love it 🙂
Honestly, the best tool for discharging is an automotive or halogen light bulb. Or you can build a discharge load out of some 1 ohm 300W resistors.
Joshua Bardwell fair point 🙂 however, have you seen the ISDT-FD100? It’s interesting and solves this problem. 80 watt discharger with automatic cutoff. And the heatsink/fan it uses looks great
m.banggood.com/ISDT-FD-100-80W-6A-Smart-Control-Discharger-for-2S-8S-Lipo-Battery-p-1145999.html
YEP. I will be reviewing it soon :-)
Joshua Bardwell cool, I will be looking out for that review! I hate having to disgracefully discharge my batteries after sessions where I break everything. I hate it even more when my chargers don’t do it properly so having that problem solved would make the process less annoying.
I also just had a thought.. you might be able to use a balance board for discharging with that ISDT discharger. I can’t immediately think of a reason why that wouldn’t work. It would be great to be able to stick everything on discharge at once
It's not a feature or design problem, it's physics...
All that energy in your batteries have to become heat in the charger (and if you have a parallel board worth of typical flight batteries that's ballpark 40 Wh into that small charger, at 10W that's four hours... )
Considering i paid $229 for my 4 way prophet!! I was astounded by the price of these products....time to buy a travel charger...thanks as always Josh!!!
Hi Joshua I always watch your videos with a big smile on my face. About this chargers: the only con i find is, you always need an external powersource for these. I mean you can't plug it in the wall.
The Q6 looks good for anything you would want to do with quads.
I could see that the Q8 may need a connector upgrade for doing high end RC (like 700+ size helis or big planes - I use an iCharger and a 1000+ W power supply for my 700 size heli). The 60A max rating for the XT60 connector (for both input and output) could be a limitation in high end applications (This is why we use EC5's for 400+ size heli's instead of XT60's - big low kv motors, lots of torque, lots of current).
The T8 has a 35 amp max input limit so I don't think it can exceed the rating of an XT60.
Joshua, I got the ISDT FD-100 discharger about a month ago and really love it. Not sure it you have got hold of it but if you do, please investigate the feature where the Q6 can be connected to the FD-100 to change its settings. At least ISDT's minimalistic documentation hints to such a possibility.
Does the FD-100 have something that looks like a headphone jack? If so, try connecting that with the "headphone jack" (obviously not a headphone jack but it uses the same connector) of the Q6 using a standard audio cable. (I only have the Q6+, so I'm kinda speculating here ;D)
Yes, the connector is over the fan outlet. Look here : www.isdt.co/fd-100.html
My ISDT Q6 plus lasted about 20 charges before deciding to just take forever to do the final balance. This has occurred with multiple charging boards and harnesses, when it occurs I do the charge on my 4 year old icharger 208B and its done within a minute.
I specifically bought the Q6 plus for the high balance current numbers, in reality it doesnt seem to matter that much.
I have done side by side charging tests between the Q6 plus and icharger 208B (4 identical 1300mah 4s in parallel on each charger charging at 14amps). When the Q6 plus was doing the correct final balance, it might end up taking about 2-3 minutes less.
I really want to like the ISDT line but will be replacing the Q6 plus on my bench with an icharger 306B and will use the Q6 plus for fast field charging.
When you compare the new T8 charger with the icharger 306B its less, has the same 1000W charge capability but has no real discharge capability(The 306b does 80W). You can add the 80W ISDT Smart Discharger for $40 but now your about the same price.
Also, while the ISDT GUI certainly looks nicer, I see no real advantage over the old 4 button interface. Takes me just as long either way.
I love my Q6, been using it for parallel charging and it gets the job done. I really want the T8. ProgressiveRC has all the lastest chargers and a lot of options. They make great custom charge cases for the ISDT chargers too.
Nice! What kind of power suppy do you use to be able to parallel charge? thanks!
Thanks for pointing out the balance port thing! I have blown up some batteries because of those stupid things on other chargers
I got the Q6 with the four port parallel charging board and the isdt PSU. Its pretty nice I can charge 4 packs at once at 1 or 2 C.
Hi,
I purchased an ISDT Q6 Pro charger. When i charge lets say 2200mah 3s battery from storage voltage. It only charge battery 1200mah and 4.2v each cell. If i charge same battery on IMAX B6 from storage voltage it fully charge to its capacity of 2200mah and 4.2v each cell.
There is also a T6 and T6 Lite on iSDT site. Banggood also has a Q6 Lite (200W 8A instead of 300W 14A) and in the description of that it mentions a Q6 Pro (Same as the Plus but with BattGO technology built in.)
I am completely newbie, feel pretty safe about the Q6. Thanks!
Happy charging? I love the ISDTs. I've had a couple had issues, e.g. the backlight on the LCD failed, but Hobbyking had the replacement arranged within hours of me submitting warranty claim. Kudos to ISDT and Hobbyking.
thank you very much, JB. please stay safe and healthy. God bless.
yet another down to earth review!!
I wish they made a dual charging version though. I've got the SkyRC D100 and that's really nice to be able to charge two different types of batteries at once
+Fincky just buy two!
Check out the ISDT D2
I love the mic!!!!
Joshua bardwell you should take a look at the Revolectrix gt series of chargers. They’re the company who makes the powerlab chargers and has competed toe to toe with icharger and have had their gt chargers which are every bit as good as the powerlab minus having the pc interface and logging capabilities and they’re half off now, I picked up the gt1000duo (2000watt) charger for 125$ recently and its amazing. The single 1000watt version is 75$. The only category the Isdt chargers beat the gt in is portability, but at the price I’d take and recommend the gt over anything on the market right now, best feature set/reputable company and great customer service
+sean metzger that's a good charger at that price!
Finally picked up one of these:) thanks for the great info
Hey Josh great content! Noobie question for ya. What type of a charging cable/block do you get for these chargers? Is there a difference in them, and any reasonably priced ones you'd recommend? Thanks for all the great info!
Getting me one o dem fancy pants chargers you eccomend Mr Bardwell:) I must also tell you that your video on the Commanders was top notch. I am returning mine. As someone who has been spoiled by the 55 degree field of view you get on transformers I really didn’t like the 32 FOV and I couldn’t get the IPD where it felt any where near normal. Your observations were spot on. If I do go for goggles it will props have to be HD3’s
+PuppetMasterFPV commander FOV is about 24 degrees. Just don't want you being miscalibrated for the rest of your life. IMO 32 degree FOV is flyable.
Joshua Bardwell thanks for responding sir:) 24 degrees!!?? Sweet baby Jesus that’s less than half of what I get through the Transformer and I don’t really have any break up or multi pathing issues so at would be a downgrade IMO not the upgrade I am looking for. What was the biggest FOV goggles FatShark has made? Would that be the HD2’s that they don’t make any more? Appreciate the help.
I'm seriously considering their 1000W model as a mobile alternative to my Powerlab 8. 12S 5000 helicopters (2x 6S in series for flight, in parallel for charging) is what I'll be using it for primarily. I think I'm over my FPV phase. I like the prices, but the thrill just isn't the same.
My Q6 has a poor scroll wheel that just barely plays nice enough to start a charge. I still recommend the charger but just get one from a retailer that will help you with issues.
NoLongo I had the same issue with one of my Q6 chargers. Horrible wheel that clicked every time i scrolled.
Great video like always :)
Can you please make a video on power supplies? What to use, what’s best, and what you need to reach each chargers full potential?
+brennen nisporic start here.

SMC racing sells a 1025watt power supply for like 70$ All soldered with 2 sets of bananna's and a fake carbon fiber wrap. www.smc-racing.net
Thx for video. I hope to see power supplies video one day.
I have the isdt SC-608. It is really nice. It can run off of a 20 dollar 10A 12v PSU.
I really like my isdt q6 but after 6 months I get an "Abnormal battery connection" alarm and it wont charge anything now. I'm really hesitant to try another one and can't really recommend one now. :(
Travis Miller i have the exact problem. How to fix this? I watched Livyu video about this my paraller charge board does not have LED. Still couldn’t find a solution. @joshua do you have any idea?
Hi Joshua, maybe a bit off topic, but can you possibly do a video about pro's and cons of reversed motor direction on a copter ?
Very interesting information and a great review. I will look into these because I'm after a new fild charger. But as for home chargeing i use THUNDER POWER TP820HVC 40A charge , in my opinion the best on the market, but they do have a high price point, but they have come down in price recently.
If a person has an ISDT Q6 charger, and an ISDT Safe Parallel Charging board, how does one send the output from the ISDT Q6 charger output (MALE XT60), into the INPUT of the ISDT Safe Parallel Charging board 'input' (MALE XT60) ?
Neither the ISDT Q6, or the ISDT Safe Parallel Charging devices seem to come with cables to bridge between them, and on the sites i've looked at, nobody seems to sell a FEMALE to FEMALE XT60 charging 'bridge cable' set to go between the Q6 outputs and the Safe Parallel Charging device... what am i not understanding??
$100???? No. NO. What's the catch? Come on. It's too perfect. Great video, as always :)
Joshua, I have watched many of your videos on chargers... lots of good information. What I would like to ask is that you make a video on ACCURACY of chargers... I have two, an Imax B6 (Original) and a HTRC T240...they both work but when using a Voltmeter (I also have 2 and they are accurate) the readings on the chargers are never the same as shown on the Multimeters.
Thanks.
I made that video :-)
ruclips.net/video/L5gAohxwOxU/видео.html
Nice chargers but they dont have power supply, which is minus points for ne.. would like to plug them in the wall..
I see it as a plus. If power supply and charger are two things you save money when one of them breaks. And as a power supply you can just use an old laptop or PC PSU.
Mr. Tux Its just me personally, I remember buying my first charger, at home I was going to charge for first time.... and could not cause I had charger without power supply, it pissed me off. Also its not usually mentioned so begginer have no idea... I have couple really old 4 button chargers with inetrnal supply and they still work after 4 yeras :) I also have one of this chargers from video, they are great but I still wish for internal power supply for easy use. BTW they sell the power supply brick separately on their site...
Seems my original comment might have been removed but I'm not sure why because this is valuable info for someone purchasing one of these...anyone looking to purchase these chargers they do no come with a power supply. If you want to power them off of a regular old power outlet, chances are you will not find a power supply laying around the house to utilize the Max current capabilities on ANY of these. The power supply Josh is using (a laptop as same do I) is only good for a low current output and most likely cannot even supply the 10 amps to run the lowest model isdt. Isdt sells a power supply for another 80$ but I've done quite a bit of searching online for a cheap one and a power supply capable of a 10amp output at say 12vdc let alone 35amp for the bigger charger is completely out of reach for most of us...we bought a 70$ charger and we don't need to spend 100$ to run it....that being said any laptop adapter you find will most likely charge your race quad batteries at 1c or even 2c, but you won't be plugging in a balance board with 8 of them with a laptop supply....let alone charging a 8,000mah 3 cell at 1c
I've got power supplies on my Ultimate FPV Shopping List:
www.fpvknowitall.com/fpv-shopping-list-charging/#power-supplies
Including a 360 watt 12v PSU for $35. Or you can mod an HP rack-mount PSU and get 1200 watts for about $45.

I have the isdt q6 and it has been great, I just got the d2 and it was DOA! waiting for the second one to come in.
Hopefully your retailer took care of you.
Sergio @ piroflip took care of it. Just wanted to chime in that there have been a couple of issues with the chargers. Still love the idst stuff.
I might need to pick this 1 up thanks!!
Awesome review. Thankx
Onyx 260 does most of the higher features, and is dual charger, all by touchscreen. $149.99. Best charger I've had so far.
Sorry, but I disagree. Its max charge rate is only 60 watts per channel, or 120 watts for two channels. No comparison at all to any of these chargers, which are rated at between 300 and 1000 watts, and practically speaking, achieve real rates of about 250 to 500 watts on 4S packs.
I don't know how you can look at a charger with between 1/2 and 1/4 the power, and costing $50 to $90 more, and tell me it's better.
You want a dual charger? Buy two Q6 and have 2x 300 watts for $120.
The only thing the Onyx has that these don't is a built in power supply. To me, that's a down-side not an up-side but others disagree. Okay, so compare the Onyx to the ISDT D2.
D2 has built in power supply, does 200 watts or 24 amps x 2 channels for $140. Onyx has 2x 60 watts for $150. Who wins?
In a real-world scenario of chargers, what will 250w give me over a 60w charger? All of my batteries have a 5A recharge max rating, and say a 6 slot para-board? I do charge in parallel sometimes, but only with 2 to 3 packs at any one time in most cases.
Awesome review. Thanks.
I wish they came out with a charger with higher discharge power for balancing. Then we'd have a viable alternative to icharger, revolectrics.
I mean, 2+ amps for the T8 is getting close to the max safe current of the typical wire used in balance leads. What more could you ask?
Joshua Bardwell I not to sure about the technicalities but withwhat I've read the discharge power is a indication of how fast the charger can balance bigger packs, like 6s 5000 700 size helis. I have a icharger 308b with 80w balance power and a icharger 108 300w charger, this only has a 20w. Or do these chargers use a different technique to balance the packs.
I have questions and would like to learn about inputs to these DC chargers. Now I know you say you can charge this many batteries that this mini amps takes this long but what about the inputs? Like a server wreck input or a CB radio DC supply or the race day quad power supplies how does that affect how batteries get charged?
I have seen your battery charger fundamental video but it does not cover exjectly what you are using in this video. Can you please make a video for XT60 to DC soldering. I can't find any good video for this part in youtube.
Great vid as always! Could you test the max input current of these, as you did for the sc620?
I assume that the Q6 will reach max output on 12v, but the T8 will not.
Joshua the input Voltage for the Q6 or SC620 needs to be higher than 12V for it to reach its 14A and 20A outputs when charging 4S Batteries. Using a 24V power supply overcomes this issue. On 12V you can only charge at approximately 12A on the Q6 and 17A on the SC620 when charging 4S batteries as the output voltage is higher than the input.
Hi, could you tell me please why my T8 doesn't discharge at more than 0,9A no matter what discharge current I set? I have it powered by a 30A 12v surveillance power suply set at 13v (so it won't drop under 12v under load). Does it need more than 13v? How come that two 3S 2200 LiPo packs in paralel can't be dicharged at more than 0,9A?
Because it is discharging through a small resistor bank and if it went faster it would burn up.
@@JoshuaBardwell Thank you! I thought I'm doing something wrong. I see now that although rated 0,1-5A discharge, also 20w so at 2 x 3S 2200mA in paralel is 22v x 1A= 22w so ther's the 0.9A limit.
Your videos are great. I have an JLB RC car where i will be mainly charging 3s stock batteries and maybe 4s. I do have two questions:
1. How can you get a this T6 charger to be plugged in the wall as AC power source?
2. Can the ISDT parallel board charge 3s batteries or is it only for 6s ? (I've seen your review on that).
1. You need a DC power supply (www.fpvknowitall.com/fpv-shopping-list-charging/#power-supplies) or you need to look at something like the ISDT D2 which has a built in power supply.
2. Generally a parallel board can charge 2s through 6S but check the specs on each one. The ISDT boards have a single balance plug for all batteries which might be what is confusing you. It's a custom design that takes all sizes.
Joshua Bardwell Great, thanks for the link in question 1. I think i may get that AC adapter that has XT60 connecting end to go in the Charger.
Yes about question two, it did have me a little puzzled with the ISDT parallel board. So just to clarify, the ISDT board port can parallel balance charge from 1s Up To 6s and Not just 6s?
Thank you. You rock!!!!!!
I know this has nothing to do with this vid but are you going to be reviewing the true D module for attitude v4s at any point would be nice to see your review before I commit to the upgrade 👍🏼
Question about parallel charging, I bought your JB edition charging board, if I plug in 4 x 1300 mAh batteries,
On my charger I change amp to 5.2, but there's also mAh battery size I have to input on my charger, do I leave that at 1300 mAh, or do I set it to 5200 mAh when have 4 1300 batteries connected
Thanks in advance, love watching your channel JB always good information
The mAh doesn't have anything to do with charge program except maybe to show % finished. How exactly it works depends on your charger. But you would set it to 5200 mAh (the sum of the individual capacities) if you wanted to be accurate.
Awesome thanks for the info and quick reply:)
Are these chargers just for flight batteries or will they work well with rc car and truck batteries with high mah like 7000 and 8000 3s and 4s? Thanks.
iSDT FTW!!!
Do you ever have a problem with the wheel scrolling when you're trying to use it as a selector. I kind of wish there was one separate button for a selector.
I haven't, but I see how that could happen.
Will the fast balance on the ISDT chargers work with my existing parallel balance boards? Or will the faster balance (higher balance current) trip the polyfuses on my older parallel boards? ie do you have to use the ISDT1-8S SAFE PARALLEL board?
Fast balance doesn't run at higher current, I don't think. I think it just finishes sooner. Anyway, no, it shouldn't trip the polyfuses. Balancing current on most chargers is around 500 mA or less.
Hello Joshua, I bought this charger but I have a big question, I adapted a xt60 to a pc charger but it only delivers 90w (19.5v 4.62a). So according to my math I can only get 5a while charging a 4s, so I can parallel charge 3 1550mah batteries at 1c . Am I right? Or does this charger pumps those 90w to the 300w that is labeled on the specs sheet?????
Sounds right to me.
Watts are watts. You can't pump watts. You can trade amps for volts or volts for amps but watts are constant. If you put 90 watts in you cannot possibly get more than 90 watts out because conservation of energy prohibits it.
I like the idea of ISDT but they don't have anything that can replace my iCharger 308 Duo yet. I like the flexibility of charging two 12S 5000 packs at 30A each out of one charger.
Nope, you're 100% right. iCharger is the product for you!
You forget to mention the non existing support from ISDT.
Story behind: the screen of my Q6 got broken after 3-4 days of usage, so i tried to contact ISDT also per Facebook message and also per e-mail, to ask them how to BUY a replacement sceen. I never got any answear from them..
This is not a bad support, this is a non existing support.
It's a shame.
I would expect this kind of support to come from the reseller not the manufacturer directly. If you're worried about support, buy from a reputable vendor like GetFPV. They're guaranteed to at least answer your emails. The bottom line seems to be that they don't sell replacement screens, so there probably isn't much to be done.
I could contact the supplier, or start a PayPal case, but that is not what I want.
Any company who will produce a good product should have product support, like all the other good companies in this hobby like Armattan, TBS, Immerson, and so one... If you have a problem with your armattan frame or motors you will not contact the reseller, you will contact armattan directly because they build the product so they heve all the know how to the product. The same for TBS, if you have a problem with your crossfire you will contact TBS support, not the resseler.
And by the way I hno I am not the only one who would need a replacement part for the Q6 but there is no option tu buy them.
Moral of the whole storry:
1, for me the Q6 is not the chatger what I can carry with me in my bag to the field to do some field charging.
2, All the great products have also great suport, that is not the case here.
What power supply is good match for the t8? Something that won’t restrict it. Don’t mention the laptop power supply or the ISDT brick.. I am aware of them for 1-3S... I am looking to charge my 5000mah 5S lipos @ 2C.
5000 mAh = 5 Ah. 2C charge rate = 10 amps.
5S max voltage is 21 volts.
21 volts * 10 amps = 210 watts.
You need a power supply that can provide 210 watts, plus efficiency losses. 250 watts would be more than enough.
The T8 can achieve about 250 watts max on 12v supply, so a 12v PSU would be fine.
I wish they build smart chargers for DIY powerwall.
Hi Joshua can you make a vid on who you made the power supply
Excellent video, very clear explanation! Thanks from a complete novice!
This is old but im hoping you respond. Could i use 2 Q6 in parallel on the same 24 volt power supply, assuming it has the watts to do it? Or a car battery out in the field?
I dont see any problems from an electrical point of view, but from a burning my house down point of view id prefer to check with an expert. Or guru ...
Yes you can do that.
I have the Q6 and noticed weirdness when charging 1S lipos for my whoops: the voltage that is read by the charger over its output leads is high. A 4.2V 1S reads as 4.9V. This is only when the charger is on that main screen (in standby mode, before charging is started or after it is completed). When it is actually charging the voltage reading is correct. I'm curious why this is. I haven't tried 2S or larger batteries yet because frankly I don't have the XT60 leads made yet. :) . FWIW the firmware on the Q6 is 2.1.0.30
When current is flowing there will be a small amount of voltage loss in the lines, so it's normal to have the voltage at the battery be a little lower than the voltage at the charger during a charge cycle. But that's the opposite of what you're describing.
I brought this up at the NewBeeDrone group on FB actually (I got the charger from them) and am more interested in knowing if this is "normal" behavior. It's not a show-stopper by any means because the voltage reading is as expected while charging -- i.e. the primary function of the device lol.
Here's the pic from the FB group showing a single 1S in a parallel board reading 4.9V (that parallel board is the only thing I have w/ an XT60 connector currently, no pun intended)

I really respect your channel and I would like to hear your opinions about EV-PEAK CQ3 100W x 4 10A four channel RC Balance Lipo Battery Charger. No one good known FPV hobby person made any review. Is this product worth any attention, maybe no?
Thank you.
Can i charge and test the resistance of 12v or 24v ups batteries ?
Hi Josh (and people)!!! Totally newbee here and I bought a ISDT q6 nano. Do you think it goes fine using a laptop charger (19v-3.42A) as power supply? I guess yes but it wont stand any parallel, am I right? Thanks for the recomms!!!
Stay under about 50 watts and you'll be ok.
I don’t get the current calculation, I am currently charging 2 3000mah batteries, what do I do? How do I calculate it?
3000 mAh * 2 = 6000 mAh. 1C @ 6000 mAh = 6 amps.
IM A COMPLETE NEWBY HERE!!! do i need a big battery to charge another battery? i cant plug this to my wall outlet? IM VERY CUNFUSED PLEASE HEEEELPP!
i think isdt make other chargers irrelevant, i own icharger 306 and powerlab 6 it is amazing how small the isdt is. small doesn't mean weak. to be frank i dont need those big sized charger anymore because why? isdt is cheaper too.
Don't hate me but went ahead and got a 620 because one was underpowered and other overpowered. Liked the form factor of 620. should hold me for a while. Negative is lack of PC monitoring but for price can be forgiven.
Best field charger is the EV-PEAK E5, charge 4x lipos without stupid parallel board
Hi Joshua is 1.5c ok to charge? 2c i think is a bit dangerous and 1c is a bit to slow.
+renato kola depends on your batteries. For single batteries most will take it. For parallel charging I think it's a bit risky.
What I really want is an affordable charger that does 3 or 4 lipo's without balance board. With all the different capacities lipo's a balance board isn't an option. Also 2s and 3s for goggles, lcd screen and tx, 4s for the kwad.
Yeah I really need an affordable 4 port charger
+audiogek fpv you can mix different capacity lipos in the same parallel board as long as they are the same voltage.
I agree with this. I don’t want to do the math or check the batts. I just want to plug them in and let er rip. JB, do you have a recommendation?
got the Q6 Pro since a few days, and i wished i bought it earlier. I had an ToolkitRC M6 before, but that didnt charge my LIPO good, and was giving error, lcd display going crazy when the device get hot.
I own an ISDT T8 and am wondering if the system listed below is a suitable Power Supply for it.
Universal 36V 34A 1200W Regulated Switching Power Supply Transformer 220V AC to DC SMPS, Thanks.
Yep that would be great.
Is it better to store at 3.9v? I've been told to store at 3.7 or 3.8 so I'm wondering what's the difference?
3.8 volts is the correct storage voltage for lithium polymer cells as far as I know. 3.9 is too high.
what power supply would you reccomend for the isdt t8? and this video a couple years old is there anything better that has come out since then? thanks=)
I recently purchased (4) 6s 1100 mah 100c Thunder Power batteries from GetFPV. From my first charge on these new batteries ( not parallel) I have not been able to get them to “full charge”. 2 out of the 6 cells just were not getting to 4.2. This is happening to all 4 batteries. GetFPV is telling me it may be an issue with the charger? Have you had any issues like this with the istd q6 + when charging 6s lipo batteries?
It's normal to see the cells not quite make it to the programmed voltage. The reason is that the charger has to decide when to finish the charge cycle or it would just go on forever. Look up "Xeno's Paradox". If you legit want to hit 4.20 volts, set the charger to 4.21 or 4.22.
Joshua Bardwell Awesome! Thank you for such a quick response.
So I can rule out the charger is bad or doesn’t have enough power to charge (4 to 6) 6s batteries at the same time?
I love my ISDT D2 Charger
What say you to their poor QC? Specifically on the Q6+, I know a lot of people have had QC issues, myself included. Hell, mine blew smoke out the back. And their customer support isn't very strong either, so the retailer is responsible for dealing with defective units.
+The Schire FPV if you're worried about that, buy from a retailer you know will back you up, like GetFPV or ReadymadeRC
Joshua Bardwell I agree that you should buy from a trusted retailer, but don't you think that the manufacturer should be willing and able to provide service and support to their customers. This was not my experience with isdt when my q6+ died.
So to charge in the house I would need to mod a laptop power supply?

Joshua, I have always JUST balanced charged my lipo's. When and How often can I Fast Charge Lipo's? and Can I Fast charge parallel?
Always balance charge. Every time. Especially if you are parallel charging.
whats the specs on the laptop charger your using that you rigged up into that xt60 connector? I was wondering what kind of clever cheap ideas there were.
+VideoGame Polak it's a random 75 watt 19 volt charger. Can't charge very fast but it gets the job done.
id only ever be charging 1 battery at a time be more than enough for me if I ever rigged something like that up..1-1.5a charge
Do I need battery balancing on the battery pack or can I join the wires to my own cells that are not in a pack and does it charge LiFePo4?, because it does not say, it only states LiPo or LiFe, bit strange.
