[@MarkH10]

I saw you interviewed on Motherboards' video about Powerwalling DIY. I came right over and subbed. I will binge watch later. I have to do 'stuff' today. I greatly appreciate you just from what I saw in these 4-5 minutes where I have heard your voice.

[@nadirsiddiqui9559]

I obsessed by 18650.. A new kind of addiction

[@1ohmwrecker]

I love this thing! I only use it to monitor my cells tho. I use a Heltec balancer.

[@HaloWolf102]

This thing is king for checking cells, but yeah. It's better to get another BMS. I can get cheap BMS's that work like a dream with no software or displays and just use the ISDT Battery Go to check if the BMS is working properly.

[@njfulwider5]

Another GREAT Video, so much better than the one I did, I will add your link for a more detailed description of the BattGo Meter!! Jehu, not sure if you have had a chance, but these guys have some pretty powerful balance chargers also. Just small enough to fit in your hands. I love using these guys products. Not so much the Batteries, but the balance chargers are Crazy awesome!!!

[@yeshecan7]

Jehu...hi I am glad to see you introducing this pcb specially this one, because someone has designed in internet and it was free to print as a board throug JLCPCB then i got it 5 pcs. Just to try...they are very BAD. I had BAD experience with them, 1st the distance of each battery is very near so that there is the posiblity of contact and short-out. 2nd 2of the 4 corner screw are very near to the battery, here also there will be battery-short. 3rd the balance pin indicators wrote incorrect sequence which means when you follow GND...first pin ....B1...2nd pin the writing sequence are not direct to the pin. In general i dont suggest that the person like you have to use this. , unless you correct those faults.

[@peterdkay]

I dont like the "weblearning"battery holder as the positive terminal grabs the battery side. If battery cover is damaged it will short out battery. Your version battery holder is much better.

[@Nostrildomus]

It's why we come to your channel . Not the sharpest knife in the drawer but your honest . . . Lol . Thanks

[@Bigislandguy]

What would you recommend to monitor and balance a 12v, 64ah. Headway bank? I’ll be using it for mobile audio. But I could always hook up an inverter to it for emergency back up.😎

[@JasonWW2000]

Did you already get it sorted out? This looks good as far as monitoring, but you'd need a much bigger unit for balancing.

[@brucebryant6483]

Jehu your killing me with motion sickness!

[@xys007]

8:13 4th and 8th are in black because they have lowest voltage. Before you replaced 1st cell it was black too, because it had exactly the save voltage as 4th cell.

[@jz4958]

I was planning to buy this one to balance my battery pack. Thanks for showing its inefficiency.

[@olly8070]

You should ignore this video and watch the hundreds of other KZbin videos giving this device a massive thumbs up.

[@nickross8181]

I really like Jehu's videos, but he might need to rethink this one. I used one of these Battgo's with 100Ahr Thundersky cells and it balanced them just fine. Took quite a while but I was very impressed. Not sure why Jehu had a different experience.

[@kevinjames5510]

Good to know hoping to find something for 60ah samsung sdi batteries.

[@mikegleasonjr]

@@nickross8181 can it continually balance a battery? Once it is finished, does it starts again when they unbalance?

[@Ziplock9000]

This video is a bit of a mess really, as others have said, look at other videos

[@mylt1z28]

cell 4 is gray because its the lowest voltage in the pack. i suggest you do some more testing and reading about this device before you claim its not good since you dont know much about it yet.

[@jehugarcia]

Context is important, sounds like you don’t get where I’m coming from

[@paridecontini9773]

is it possible to know how to disassemble the batgo? I would like to open it to add a relay

[@sciencetechro9701]

Hello. Can it be used to monitor the battery from the smartphone? The battery can not be removed from the phone. Can be monitored while discharging the battery through usb or other method by this controller you present? Or other product that can help me. Thank you.

[@nosmokenojoke08]

i love watching your videos, you give great information. but please if you could get a steady cam.

[@jehugarcia]

No steady cam allowed on this channel

[@Nostrildomus]

Data logging is important in my mind . At least in setting up any battery , balancing amounts to a pocket full of resistors . . . Lol . Thanks

[@lpi6608]

if i have a 15s battery system do i need 2 of these

[@The.2.Minute-Man]

Hey Mate really enjoy you're videos on the 18650 / do you use the 26650 battery..

[@timmyseegobin196]

Can this work on 3 banks of lithum

[@ALSANMAT]

Hey Jehu. I have a 20s battery, do i series the three balancers? With the last positive sharing the first positive of the next one?

[@shinos9917]

Is there anything like that for a 16s?

[@_el.guapo_]

Maybe it's best to have a cell logger which only job is to show you the voltage of each series (+ alarm trigger). Then you can use a hobby charger at home to charge + balance them.

[@Mark-bb2zx]

Have one: great device, mine runs 24-7 in my DIY lifepo4 150ah power qube.

[@jehugarcia]

Keeps it balanced?

[@mikegleasonjr]

once it balances the cells, does it start again automatically when they get unbalanced? I am looking for a 24/7 cell balancer. Thanks

[@Mark-bb2zx]

@@mikegleasonjr I'm not really using it for cell balancing, more for cell status. I recommend the ISDT T8 BattGo because it will dissipate the uneven load variations much more effectively. Once balanced, I would not want to allow any kind of active balancing device to mess with the cells. The Calb cells inside my 1 foot cube power unit seem to remain within 10 or 20 mv's even after weeks go by without charging or loads connected and the BG-8s just goes quiescent with only a dim pulsating led to let me know its alive.

[@mikegleasonjr]

@@Mark-bb2zx Thanks for the comment! Planning to start solar charging 18650s so I was looking for a battery checker since my solar charger already takes care of the overcharge and over discharge aspects.. thanks again.

[@Thisoldtech]

Nice video I like to see products in use. What if you dip the the positive clips in rubber. Like the rubber that covers tool handles. Or cover the clips on the positive side with capstan tape.

[@jehugarcia]

Yeah except thats more work and more money than using other type of holders

[@marcosmmfreitas]

I'm building a 48v system. A Batrium BMS is good for me?

[@olly8070]

Batrium BMS is very good, but a little expensive.

[@ljprep6250]

What about the Chinese BMSes? BMS Protection PCB Board for 3S 4S 7S 10S 16S 18650 Li-ion LiFePO4 Battery Cell ( 182649915121 ebay) The 10S is $10.28, rapidly delivered in just 6 short weeks. LOL. I'm trying to make 36v ebike batteries. What about 10S and 12S chargers and discharger/analyzers?

[@sunkidsni]

Would you share that 7S battery holder link from Web learning? I am interesting to get from them.

[@kataseiko]

That extra plug on the side is a power supply. Just search for "ISDT Connection Cable Cigarette Lighter 12 V" on Amazon and you should find two versions of that already. There's also versions for banana plugs in male and female.

[@a-dayeight5906]

Hi ! i have 2 of these units and i'm still on the fence about there worth as jehu mentioned you can't get the others anymore

[@jehugarcia]

Yeah the battGo is really limited, you can’t even set the screen to stay on

[@a-dayeight5906]

However ! Battgo's C4 is what every 18650 is copying it is a true beast but only handle's 2 cell's epic fail but i do have 4 at the cost of $240 ouch.....

[@olly8070]

I think Jehu is confused. Battgo is not limited, Battgo is not the BG 8S. Battgo is the battery tech used by the ISDT BG 8S which is not in this review. Jehu, did you actually read the manual before deciding to review this? Seems odd that all the other KZbin reviews of the BG 8S manage to keep the screen on for their reviews but you can't?

[@jehugarcia]

I haven’t seen anyone else do 20. Hour long time lapse tests on this device, have you? I don’t read manuals

[@a-dayeight5906]

BattGo is a great company and i'm not saying so because i own several models in duplicate but the BG 8S was not a planned purchase i bought it because it was Battgo....it has a few flaws it's not a deal breaker but it does need a firmware update

[@gaberBoB]

Where can I get such battery holder?

[@laurentsosson1739]

Hello the balancing current is 1A? 17h for balanced?

[@Royaltea_Citizen]

Jehu how did you loop the 16 ribbon cable down to 8? Regards

[@jimzak6883]

Yes, share the link for the adapter!

[@CrAzYDr1veR]

hi can this take more than 5v on each cell?

[@adam_the_nomad]

Did you get a chance to explore this or other balancers that behave the way this one did in the video when you removed the 1st cell? I bought your 7s starter kit and I'm repurposing the BG-8S for a smaller 24V system, much like your stackable modules, just with the LiPos from Ring doorbells, from Battery Hookup. I have most 7s packs working with balance leads connected to a little PCB breadboard with an 8pin IDC male on the end, emulating your design with 8pin ribbon cable v. 16pin. My question is regarding my struggle with my wiring/soldering/? causing strange behavior. When I plug a good pack up to the BG-8S, it show 1 through 7 all good around 3.9v and I can balance them, etc. However, a certain pack will show values 1 through 8 with values > 4.2v and 8 shows 1... v in RED??? I've checked all my leads over and over again. I test all the cells individually with a voltmeter and they all read around 3.9v, I then test all the pins of the IDC connection and they all read properly Neg to 1: 3.9v; Neg to 2: 7.8v; etc. up to 27.3v for the full pack. I don't believe there is any shorting going on, otherwise the output at the pins wouldn't increment properly...right? Just tired of scouring the interwebs for troubleshooting when every review is less useful than yours, for the most part, starting with how to remove the shrink wrap on the box...sigh... If you have any video I haven't come across in your arsenal, or any other community members that understand what my issue is please share a link to help. Thanks...you transformed my life into exploring off-grid living so much so that I bought 40 acres of raw land and feel completely empowered by just your powerwall builds to know I can succeed. After getting this 1Kw ammo can "Sunny" working, I'll be building a 5Kw unit with some 200Ah LiFePO4s, currently on a slow boat from China. But, I need to get an understanding of this issue first.

[@swaleedkhalid]

can we use this battery meter on 12v AGM battery ?

[@jehugarcia]

Yes

[@Marginal391]

Hi Jehu. Could you please tell me if this unit is suitable to balance 1866132 lithium polymer batteries please? Regards 🙏 ✔️

[@AmmarAbotouk]

Seems good though the balancing thing I think no body is going to balance 0.5V that way too big though its good to know it didn't work when that happens I would love to see how it will do for more reasonable .1v or more maybe ?

[@jehugarcia]

Yup it does ok, I did record that but I didn’t think it was helpful as I couldn’t tell how much energy it was burning. 1ah = 3.6wh and it took semewhere around 15 hours = .24w per hour = 66ma balancing

[@AmmarAbotouk]

@@jehugarcia I see thanks for the info and your hard work.

[@ninehundreddollarluxuryyac5958]

I keep watching videos about these things and nobody knows or is willing to say exactly how they work because the instructions are rubbish and everyone does a quick review before they know how to use it. I charged my 4s LiFePo4 battery, got the meter into LiFePo4 mode and applied load. I'm measuring load over time to determine the batteries capacity. Soon this thing is sounding an alarm. But why? What does the tweedle sound alarm mean? All cell voltages are highlighted in red, but are within nominal cell voltage limits. (3.298, 3.305, 3.302, 3.308) 13.2V for the 4s pack. Why is it sounding an alarm, and what is it trying to say is wrong? Why is there no useful instructions and why are ALL the reviews superficial and devoid of any useful information a person would need to know when actually operating a battery using this monitor? How about working with it for a while until you know how it works, or even just how the monitoring function works and doing an instructional video about how to use it and what the alarms and display red highlights mean? Do I need to hear it sound the alarm every few minutes even if I just want to use it to monitor the house batteries?

[@Ziplock9000]

All of his videos seem to be like this unfortunately.

[@JusstyteN]

Hello thanks for the video. it seems to be a good meter. I want to use this on LTO (lithium titanate) 2.4v nominal batteries but it seems to not have option for them, can i still use this as meter and balancer?

[@olly8070]

No, supports LiHv, LiPo, Lilon, LiFe, NiMh/Cd battery and BEC output measurements.

[@thinshadow6669]

I plan on buying it for the same purpose as I imagine it should at least work to measure the voltage of each cell. What would make it unable to read their voltage??

[@Silpheedx]

Instantly does everything to break the ISDT balancer lol

[@randycarter2001]

A thing to note: The device is powered by the batteries it's testing. Not good. It does not know when to stop drawing power and will drain the cells to dangerous levels. A beeping alarm is not adequate. Batteries don't care if the alarm went off. The chances of you being there to take care of the situation are slim. NEVER leave it unattended. If you leave unplug it and resume when you return.

[@youmakeitreal]

Which "device"? How much does it draw? What "situation"? Need more information before I panic.

[@olly8070]

All of this type of battery checker are powered by the batteries they're testing. But not all have an alarm to tell you something is wrong ..

[@jehugarcia]

No need, panic is in order in this case

[@JasonWW2000]

Does anyone know how to remotely turn the unit on and off? If disconnecting one particular wire can turn it off, I would think using a relay to connect and disconnect it would work fine.

[@joecachia2]

The grey cell , is the lowest . its the one that won't be losing charge

[@3000gtwelder]

What is the best board to buy to make a battery bank? I am going to be living off grid in Hawaii, and I need to build a battery bank. I want to use 18650 cells.

[@jehugarcia]

It’s too early to tell, we’ve all just started developing our pcb based battery packs, watch my video on the subject about a month back

[@olly8070]

Magic - PCB's are ok for small solar batteries, for RV's sheds etc.. But for large off grid systems they're a huge unnecessary cost, don't waste your money ..

[@3000gtwelder]

@ jehugarcia Do you have a link?

[@3000gtwelder]

@ UK DIY'er Why?

[@3000gtwelder]

@ UK DIY'er I don't need 30kWh, And I can't do the math, if I don't know how much the PCBs cost? Anyway, I guess he's just wasting his time is what you are trying to say? It sounds to me like it's just not right for you, because I see a lot of people going this way, and there must be some reason they are using Li packs.

[@JorgeFlores-ck8bp]

it is so crapy , can we get the old one ?? the one for 15 dlls ?

[@milesmoore5422]

What does "Delta" mean ?

[@JasonWW2000]

It means the difference between the highest and lowest. In this case, how many volts between the highest and lowest cells.

[@nickgalena1]

My question for ebike charging and controll is: Can you monitor if the BMS does work properly ? Normally i balance charge my 14s 7p ebike battery with a junsi 308 icharger. (dual channel: 6-8 A current) But with a 14s 7p BMS which I would like to use how can I control the batteries ? There is only a 8s monitoring tool like the one you showed: iSDT BG-8S Smart Battery Checker. Can I go into the 14s thin cabels from the BMS in parallel to get extra 2 separate 7s connectors which I could possibly control with a Battery checker ? Or is there a simple and efficient solution which I dont see at the moment for this problem ? Thanks

[@mrtechie6810]

Yes. But you will need two, and an adapter.

[@66bigbuds]

The sell one that charges too only $20 more

[@kwiatas66]

Looks like I wested my money to buy this to balance my wall:( What next the Batrium ??

[@Ziplock9000]

Nope, it's the review that's bad

[@stealthbanana]

Bit of a rushed video there. I have one of these and it is great when used for its purpose, checking RC batteries in the field and dealing with any slight misbalances, or acting as a quick USB power supply. When balancing, the cell in that was black is the target voltage for the operation, eventually, all turn black when finished, it is a passive balancer after all, and I would look for an active balancer with that size imbalance. It also has the function to check RC recievers and the protocols used for fault finding. Not a fair review at all.

[@jehugarcia]

Great for small batteries not great for big powerwalls, did you watch the video?

[@stealthbanana]

Yes I did, and I stand by what I say, it is a cell checker, for use in the field, with a balance function, for aimed at the Radio Control user, hence all the options to check the functionality of RC protocols which you did not mention at all, that is what it is sold for. In the manual, the cell balancing function that you spent most time covering is the last function mentioned. I use it for checking if a battery is healthy when changing over when flying, and if I need to balance them on my charger when I get home, I also have something that can check the RC system in case of problems. Your test was a bit extreme, as you said, and in correct use, the battery checker would have shown you the problem with such a huch disparity in the cells, so you could take action on more capable equipment. At least you could have read the manual, and explained what BattGo is properly. Shame, as your videos are usually excellent, but everyone has to have an off day.

[@jehugarcia]

I don’t care what it is good for, I only care that it’s not good for what I need it for and for what I see a lot of viewers think they want to use it for. I didn’t say it doesn’t work on small packs. I you shura you watched the video?

[@stealthbanana]

Yes, I did watch, The closest analogy I can think of is if you used a Swiss Army knife to butcher a cow, yes it will do it, not very well, will take a long time, will make a mess. There are much better tools for the job, but these tools would be useless for doing other jobs you can use a penknife for, such at that tool for getting Boy Scouts of horse's hooves or using the Corkscrew to open wine; therefore saying you cannot recommend it because of this one test is not honest and not very good. You neglected to mention anywhere in the video that this is not what the item is designed for, or marketed at. It is a diagnostic tool for a niche market. This is meant as honest criticism, no need for accusing people of not watching the video, or working for ISDT as you have done elsewhere.

[@jehugarcia]

This not comprehensive review, stop criticizing it as if it was, I make powerwalls this device sucks as powerwall balancer, for all out there that are thinking of using it to balance big battery packs, Don’t, it doesn’t work well.

[@jehugarcia]

Alright people. This device failed to balance my small pack. That’s all I’m showing you, if your argument is, “yes but”. I don’t care

[@jehugarcia]

Well thinking about it, I might be wrong, it might work, I mean it’s still way too inefficient but if it doesn’t run out of battery by hour 30 then I might just finish balancing 1Ah

[@SripalTAD]

jehugarcia hi how r u . Use the usb port to discharge more current and balance faster, It works. It can go 10w easy

[@mosfet500]

@@jehugarcia This device is not designed to balance quickly, you're dismissing it on the wrong application. This is the person who disagreed with me a couple of years ago when I said you need BMS control of packs. Then you didn't know that batteries have a maximum charge current per manufacturer's specs. Then you reviewed Tenergy LiFePo4 batteries and said they were poor performers because they didn't have high peak current capabilities completely missing their application. The best batteries for power walls are LIFePo4. They are safe, don't explode and have high cycle rates. You don't need super high peak current capability in power walls. But actually I bought 640 of those Tenergy LiFePo4 batteries a year and a half ago. I got them for a steal on eBay probably because a lot of people were listening to you and buying Li-Ions for their power walls back then which I would never use. Please educate yourself, you don't know electronics and it's a complex field, you can't keep oversimplifying it and making statements that are wrong, dangerous or can cause harm. Batteries need very careful handling and use. People be careful, if you want to learn electronics do it from a good source, someone like Dave Jones on YT who knows the field.
