First look at the ISDT N24, a 24-slot battery charger for AA, AAA and 14500 cells.

I like all the features available from the display menu. I didn’t know such a monstrous charger was available. Thanks for the exploration!
Another one for my ever growing wish list! Great review, thanks Julian.
That rainbow of eneloops is lovely. Julian, you could make a lovely jigsaw puzzle out of that picture!
From an iSDT manual online.... *_"Activation and restoration functions of excessive discharged battery: When the charging task begins, a 0.1 A current should be applied to activate and restore the battery if the cell voltage is tested to be lower than the pre-charge voltage; on the other hand, it should be adjusted to a rated voltage for charging when the cell voltage is higher than the pre-charge voltage. This design can protect excessively discharged batteries, as well as conduct activation and restoration."_*
I was right! That’s what I thought but only for resetting protection IC’s if the 14500 has it but I guess it is for any chemistry that is really low voltage cool!
Man, I wish that they made one of these for 18650's:) Great review, thanks.
LOL...can you imagine the size of the power brick you would need for a 24 slot 18650 charger..... it would need to be at least 12amps if you were going to provide 500mA to each cell , and the size of the circuitry to handle that beast and the heat dissipation...its like a desktop bomb....
@@sortofsmarter The 5V line of a computer PSU can do over 30A, enough to drive a rack of 24 TP4056 boards at 1A, and for a lot cheaper.
@@ahaveland True, I'm not saying it isn't possible. But depending on circuit design and chip demand you would need more than 5 volts. Even if you passed the current through one schottky diode and had no other losses in your circuit would loose 0.46v right there and now you dont have enough to reach full charge. But there are definitely ways just not cheap...
@@sortofsmarter No Schottky needed. Please read up on the spec of the TP4056. I know what I'm talking about because I've built a parallel independent charger for just a few quid.
They take 5V, and regulate it to follow the charge profile of a liion/lipo cell according to its state of charge.
Make two thick busbars, supply negative at one end and positive at the other, hang the TP4056 boards and 18650 sockets off it, and you're done.
@@ahaveland I have also built a similar board to charge 6 18650 at once, But i was implying a commercially viable unit like Julian's in a "all in one" form with a touch panel and a single interactive screen to display all the data for the entire unit. Just needing to add power to it.
Why didn't you open it up and see how it works?
Does this charger use negative delta v for NiMh termination charge? I don't see a temperature sensor. In that case I'll stick with my Maha Powerex because in reality very few users use the Lithium chemistry in AA size.
I'm not sure yet. Most of the eneloops have been topping out at 1.50V almost as if it's terminating at that voltage. But some have only made it to 1.40V. Feels to me like it's delta V but with 1.50 as a maximum.
i see this unit being very usefull for company use. media companies for example.
and youtube reviewers... :-)
@@ahaveland More and more I'm feeling like watching home shoping TV. Reviews are advertising. BTW, rechargeable AA cells are quite useless today.
@@dorfschmidt4833 I think the same but look at photography channels. Camera flashes and stuff still use AAs
@@CZDrMike Yes, I have four AA Eneloop Pro and two AAA Eneloop for my flashes. Some old Pentax DSLRs run on AAs, but otherwise serious gear has LiIon batteries.
Dunno - probably a bunch of the cheapest type of wall wart charger available would be preferable... so you cant get one wally disabling the entire company by mucking around with the setting or otherwise busting it ... don't like the fiddly lip at the +ve end requiring the use of a sharpened lolly stick for something in daily use use by group of people of unknown brutality/clumsiness either. I think it's really for one careful person with a lot of AA batteries... i.e. a Julian
Activation is probably refresh cycle(s) to re-activate a dead cell. Did you figure out what it is?
On the C4 you change the chemistry per slot. Not with the N series?
Oh wow! That’s a lot of bays! It could totally use a firmware update to be able to change chemistry on a single slot ( but reset once the cell is out) thanks for sharing that monstrosity!
Activation usually should be used on new cells as it will try to do a break in to get maximum capacity from the cell and it is done by doing some charge / discharge cycles.
Julian, I would rather see you working with some electronics design, etc. than seeing end user products. Time to get back to building *_stuff!_*
I like to do a bit of everything. I have more time now, so my productivity should improve :)
Can it be used to test capacity of non rechargable cells, like alkaline, zinc-carbon or zinc-chloride? Is it possible to set custom discharge voltage threshold?
Also does it measure mWh? That I would find very useful.
This one seems rather good for keeping cells healthy. The charging method used by my wall type units does track voltage, but is very basic in comparison. I think i like it.
Does the n16 n24 include it's own power adapter in the packaging?
what is the diffrenence with charging NiMH between NiCd? i charge NiCd with an NiMH battery charger and it charges just fine no issues
How do you find this charger after 3 years of use? Do you get a high pitched hum when you are charging 24 batteries at the same time?
ANOTHER GOOD INFORMATIVE VIDEO!! THANKS FOR SHARING.
Activation is likely to be an initial forming charge (break in) for new (or long term unused/uncharged) batteries, at something like 0.1C for 16 hours..
On further investigation, I think it's Charge-Discharge-Charge, but you have to set the current yourself.
I first thought of it being able to reset the protection on 14500’s that have gone too low, but that is a niche feature
It looks to me the Analyze does a charge, discharge, charge cycle, while Activation does this three times and also accepts ridiculously low voltage (I tested with 0.2V 15 year old never used cell). While Cycle does this 5 (or more configurable) times.
does this N24 (and N16) come with a 12V charger?
I just bought some Deleepow Lithium Polymer AAA batteries and the unit does not see them and makes full contact. Would like to find some LiPo's for my TV remotes that work in this charger
And you didn't put them in resistor colour code order :P
If only there were red eneloops :)
Or rainbow Hahaha! Nice one
I got cute coloured AA ones from Lidl (Tronic). They costed 3 Euros per 4-pack. The packaging said 2500 mAh and I measured them (discharging with my Accupower charger/measurer) as ~2260 mAh
What power supply did you use for this battery charger?
Hi Julian can you do an update for lithium cells used with this charger please
It is HUGE!
Real shame about the poor design regarding the flat top batteries though.
Could have been sorted very easily with a button on the top of the charger to move the positive terminal position inwards slightly or just not have that terminal recessed.
However.
I suspect it has been designed that way to discourage reverse insertion of batteries.
Jason Park Moving the terminal won't be easy, as it's obviously just a dot on the PCB that also holds the LEDs. Avoiding the recess would just need redesigned plastic, but would risk reverse insertion.
Is it possible to charge 1.5V AA lithium batteries?
I actually do not have anything in the house that uses AA batteries. Even the AAA (phones) charge in their stand. Everything else is 18650 or Lipo. Will AA batteries eventually die a death?
Is this a valid therapy for ocd victims?
It's working for me - and it's a wicked hand warmer too :)
Does this charger let you set the charger percent such as 80% to extend the life of the cells?
No, it's a fixed charge algorithm.
Julian, at Banggood, they say it's a touch panel. Is it?
There are 3 touch sensor buttons to the right of the LCD. The screen itself is not touch sensitive :)
It would be cool if you could set like the first 4 to something like nizn or something
Why do they make eneloops in so many colors ?
Connect the scope while charging please
Oh my, that's one hell of a long charger.
Thank you for this video 👍🏻 Can you tell me witch is the better choice between ISDT N8 and ISDT C4 ?
İf you want to charge 18650 you should buy ISDT C4. İf you are using only AA / AAA you should buy ISDT N8. ISDT N8 charging AA / AAA size of li_ion batteries too. Im using ISDT N8 and fall in love with it 😂 so I bought 5 pcs ISDT N8.
flap jack 😁 Thanks 👍🏻
@@bidiboutmovies N8 is soo good😉
@@bidiboutmovies You can buy from BANGGOOD. I bought from there.
flap jack Many thanks.
Danke für Dein Video, denn ich hätte mir das Ladegerät bestellt. Nachdem ich 8:34 sah, bestelle ich es leider doch nicht! Wie kann man nur so einen umständlichen Murks fabrizieren?
Die Firmware erlaubt mittlerweile das setzen der Chemistry fuer jeden Slot, und wenn alle Slots leer sind, dann uebernimmt er im Default die Werte fuer den nächsten.
exactly hwat i imagined to build for my 18650 Batteries, i first thought i build a 12 slot but now i think 24 slot isnt so insane anymore ;D
It is $125 on Banggood go to one of the eBay Chinese location sellers in their stores find the exact same charger without the brand name on it white box series it’ll be about half price
IKEA have a really nice 12 battery charger for $35 if one don´t need the fancy discharge or lithium capability
Spot on, ebay or even aliexpress and you don't have to risk getting your money back from Bangbad if the thing isn't delivered..the lying thieves.
and maybe it will even be the same thing, and not just a cheap look-alike clone!
Sylvan Butler Exactly this is the little secret I stumbled upon purchasing some products from particular Chinese eBay vendors sell exactly the same product out of exactly the same manufacturing plant in a white box with either no name on it or offbrand Chinese unknown name but still the same product just re-labeled and re-boxed and when sold to the American public the price doubles or triples
Take it apart?
Julian using mains, now that's a first
Yeah, I'm never happy having to resort to mains.
I know :)
I can't wait till you get the super capacitor from FWG. I'm very curious what your findings will be. :)
I can't wait too :)
AA! What's going on ear then Sonny? He said bending at the knees with hands behind his back.
Damn I thought it's for 18650 as well, was hoping someone finally has created a charger than can help with large 18650 battery builds as each single battery needs testing and it's painful with my 4 channel charger/discahrger/tester
Nifty little charger and it's good that you managed to hunt out potential problems for anyone considering this. I'd probably consider a smaller version for my eneloops and 18650s.
OCD. All the eneloops are facing up.
OCD. You noticed!
Yes, I have orientation consistency disorder ;)
Julian Ilett 😄
@@JulianIlett But it's not ordered and/or arranged by colour! Unacceptable!
That's colour order disorder - I don't have that :)
Se alimenta con un cargador tipo C de celular de 5v QC 3 de 2.5 A?
Gracias hay algún cargador mejor que esté, pero de no más de 8 unidades a la vez, gracias!
Is really good idea to buy a 1.7 v Ni-Zn batteries for replace a 1,2v recargable AA or AAA batteries?
PD: poseo ya un Litokala Lii-600 y Un Li-500.
PD: really? A Eneloop Mode? I really success?
PD3: cómo saber que mis Eneloop son originales?
Qué tipos / series de Eneloop hay y cuáles son mejores? Diferencias?
That's nice, now they just need them for the bigger Li-ion batteries.
Yeah, a similar unit for 18650s would be cool - with a motorised print-head to print the capacity onto each cell :)
@@JulianIlett Just put the whole charger in a tray inkjet printer, and write a script for it :D
@@JulianIlett Ha Ha, but now come to think of.....hmmmmmmm!
Thats so huge!
Hmm, £99 for a charger that takes 24 cells. I don’t think I have 24 operational individual cells...!
The difficulty of taking out the batteries and the requirement of a "hack" to use certain batteries is a major design flaw. Someone was going for looks over function and didn't do any prototype testing before making the moulds.
How has this product held up to today? I just so happened to favor 24 batteries per case and have 24 eneloop pros and 24 eneloop standards in my arsenal at all times. This is the perfect charger to replace carrying around 3 4 bank chargers like the Opus.. (take care of 1 case in a SINGLE CRACK??? Excellent!). the 3x 4 bank chargers only do half my empty case at a time. So this would be perfection. provided it is accurate and any good. So how is it?? this has been around for 4 years now.
I just purchased n8 charger it now uses usb c power connection
It's too bad this does not have a voltage output socket so that if you are in an off-grid scenario and discharging an array of batteries you could feed that power into something useful
Now we know why so many outlets show 'Out of Stock" for Eneloops...
The IKEA batteries are apparently 'white label' Eneloops, according to something I watched the other day. The key, it seems, us that they're marked as 'Made in Japan'. Who knew?
Much cheaper if it's true...
duncan amos it might just be a knockoff rendition that uses the same chemistry for low self discharge
@@SuperBrainAK That was initially what I thought but this puts forward a compelling argument (as do several other sources)...
m.ua-cam.com/video/Jeo_hv-8bHI/v-deo.html
@@duncanx99 It's not true. I've analysed the IKEA battereis and the Eneloops . The Eneloops always have higher capacity than what's on the label. The IKEA batteries are always close to or below capacity stated.
The only way to improve thag would be to have a plug moulded into the package. It might damage the wall socket, but it would look so ridiculous I wouldn't care.
How on earth did you get all those different color Eneloops? Do they make, or have they made in the past, that many colors? EDIT: Silly me Google has all the answers. I didn't know they produce limited edition colors/themes.
good video! T series: nope; N series: yep ;)
oh Missis, that's a large one
It’d probably take a week to discharge 24 batteries with this unit. Most hobby chargers have... basically a heat element with a fan blowing over it to discharge batteries and this clearly doesn’t, so I don’t know that I’d plan on using that feature. That said, I just ordered one(n16) because there’s a giant hole in the market for AA chargers of more than 4 at a time that I would trust to not destroy batteries and/or catch on fire. Yes it’s pricey, but so is everything else from ISDT and it’s worth it to me.
Bloody hell I want one lol
holy hell
If it could accept 18650, and be controlled via USB (set per-bay modes and limits; and data log voltages and currents lets say every second), it would be an amazing device. The built in firmware is reasonably nice. The graph definitively needs voltage and current units on y axis, and time or capacity on x axis. Not hard to fix. Hacking a firmware (or writing it from scratch) to do it all, shouldn't be super hard, but would be nicer if the source code is available. But lack of 18650, is a bummer. Also, would prefer 32 bays, and 100W , 24V power supply. :D I guess 12V is nice, because you could power it directly from car or 12V battery.
There is analysis mode. I wonder how it works exactly. Would be nice, it it could optimize discharge and charge, so when in analysis mode, it discharges some cells, but instead of dumping power it into resistor or mosfet, it uses it to charge some other cells. This way one could even make it almost self contained unit, and not need external power, or very little. Sure, you will eventually need to connect it to power, as there will be losses in redistribution.
well that's a nice one nice to see some orange cells I like it but its a bit big for me I would find it difficult to use more than 6 !
ye! It's massive. For what it's worth, they appear to do an ISDT N8 which has 8 bays.. it's like £40 though (17% "off")
Thanks Ollie B bit pricey but if I ever need a reason to use that many AA ,s I'll buy one
Good lord, that's a monster :)
Your thumbnail is a sight for sore eyes 👀
Nice innit? Shame 7 bays have failed (yes 7).
@@JulianIlett thats a high number of bays that yielded up there life before there time. 😔
That's a damn nice charger to get for free!
Nice but very pricey,don't they make.a.smaller one,great review.
Actually they do ;)
anyone has any idea of designing a DMX transmitter?
"All 17 inches!"
That's what she said. :)
I started to like it as I have seen it in the websites, but...
8 slot has only USB input?
You can't set up by channel what you want to do?
Well, thanks but no!
That's a battery and assault charger!
Nice if you have a charging room:>)
As it doesn't do 18650s there's a very limited market for this.
Anyone that wants a 24 bay 18650 charger would just make their own out of a pile of TP4056 boards and a computer PSU as I and many others have already done.
It's good it can measure capacities but better if each cell's info could be selected by touching a sensor below the actual cell. The menu interface and number of clicks required would get quite irritating quite quickly!
My guess is that it's aimed at users of radio mics or walkie talkies.
@@JulianIlett Not my industry, but it sounds logical.
@@JulianIlett Yep that is my use. Sound departments for film use these quite a lot.
I was tempted but not at £97
whats this hype about eniloops? I have never heard of them. Whats wrong with duracel?
Crap! $125 worth.... Can Bangood send me one for free please? ;-)
massive beast, but kudos that color palette it looks wicked.
it reminds me a little of the Efan.. just taken to the max and perhaps also with a lesser advance feature screen hence graphs lygte-info.dk/review/Review%20Charger%20Efan%20Lux%20S4%20LCD%20charger%20UK.html
but when it comes to chargers a lot has to do with how these chargers actually charge the batteries and the cycles... and if they are "nice" to the chem/battery and nurse it along or simply "foie gras" the current down the throat in abnormal pulses.
it doesnt look like this N series have been analyzed.
lygte-info.dk/info/roundCellChargerIndex%20UK.html
Teardown or it’s never existed 😁
It's not a good review. Its only advert because he got it free. I bought 8 slots version N8 and I lost my 50 bucks. It cant charge any LiIon (tried 14500), LiFepo4, LiPo, LiHv which declared in manual. It is bad unusability expensive toy with color lcd only. For ordinary nimh. It charged 8 AA after 34 hours! It's,, fastest,, charger?! Not more!
Wow, very expensive.
Yeah 3x N8 would also charge 24 batteries and be cheaper and more flexible. ;-)
When you say "interesting feature", you really mean: weaknesses? Right? Because as you noticed yourself, 1.5A times 4.34V times 24 is.... nearly 160W. Also not being able to assign chemistry to individual slots... meh. All this fancy interface, but no real value added.
Хрень конечно прикольная ну только я не хера не понял чего там говорят а так смотреть можно
Sorry i didn't watch the full length of the video. Must say the video's are getting less interesting with all this donated, way too expensive banggood stuff, that i won't even consider to buy. I'd rather see the (very) inexpensive stuff that anyone can afford. Way more interesting ! Pity...
Fell asleep.
