More than a year watching your videos and waiting for the day when I can assemble a great Battery Pack. But here in Brazil this day never comes. For now it's just some pack of semi-blown LiPo cells. ;) Thanks for the videos.
Excellent video @jehugarcia! You didn't notice at the time but when you tested the last battery, the meter showed negative voltages, while on the previous tests it showed positive voltages; so It does not matter which way the connection is made, it still shows the individual voltages and tells you if the 1st pin goes to a negative or positive end of the battery.
Cannot believe that this really exists - I have been searching and searching - had given up - and then BAM - it's here! And thanks for the heads up on the other cell checkers - I was wondering if I could use a setup like that - now I know. I like that it has a separate power supply - the idea of only turning on when needed is a real plus - didn't want to leave on all the time.
Wow. This is EXACTLY the problem and solution I've been dealing with! I'm literally using two BG8S meters for a 14s 48v (Nissan Leaf golf cart ) battery just like you're doing. They've been plugged in about 18 mos. Pack is a bit unbalanced just like you describe here. I keep the balance function of the BG8s on the higher half constantly just to try to keep bringing that side down. Always wished I could just get a damn 14s cell meter. Finally!
Glad you found this, I too have been using those 2x good old BATG-8S and its been serving me faithfully for few years... If its made specifically for this purpose without other bells & whistles, there's good chance this can't miss its intended purpose.
You have very interesting films, they teach and help inexperienced people like me, I am from Poland and I also run a channel, but on a different subject, what you normally grow every day is a delicacy for me that I have to keep
Scott Bennet, the manufacturer says that only one set of pins will work at a time. So hooking up a balancer to the other set of pins probably wouldn't work.
7:46 I have some Makita batteries and want to know under load how many Ah I am using. They are for a lawnmower so it uses 2 batteries at a time for a total of 36V. What meter could I use?
Do you know the minimum voltage between cells it will read? Wondering if it would work on a 24 series of 2V lead acid Cells? To be able to easily check the voltages of each cell, that’s all. TIA
Ive got a bunch of ES2 expansion batteries for the scooters. Any word on when you're going to do a video on how to use them? I'd rather not break them down just to build another pack
Hi jehu. On that last battery 14s can you point me to the bms that I need for it I just received mine from you by the way very nicely packed..looking for 40amp one bms just want to get it right the first time I order it thanks and bless be safe.
I'm just putting this out there for anyone else coming along in future trying to solve this problem. I'm building a 36V pack with e-scooter batteries that I've gotten for a song. The plan is to buy a 48V Victron inverter/charger which has a low voltage cut off at 38V. I'll pass that output through to the AC-In of my existing 12V Victron Multiplus II to passthrough. If I bump against the 38V cutoff voltage too frequently it'll be cheap and easy to add more e-scooter packs. It will allow me to tear these down and build a proper powerwall in future if I really want to without being sucked into a 36V sub-system I wouldn't otherwise choose to use.

Dude. Your vids are so good. Sometimes i re-watch just to chill. hehehe. Cheers from Brazil

Hey that’s cool, you plugged the last battery in backwards and it shows you all the voltages in negative
Very nice looking unit. Would be awesome if it included a settable alarm to alert for low voltage cell and high voltage cell.
Thank you for the excellent video, having an external power source allows the device to be more accurate. It is a pretty cool device.

Could just turn an ant bms into what you were looking for. They even come with a display or Bluetooth. Not as elegant but would also balance.
Awesome, been looking for this for electric scooters. Just ordered it now.
What does the SD memory card slot do ? ... on the same side as the 5v/USB power input .. data logging , firmware update, nothing ???

Can you link to a BATG-8S, can't get any results 😕
3.9.22 Jehu, are you going to stock this item so that people can buy from Jag35?

add an extension A/B pinned switch - concern solved.
Enjoy your trip- Safe travels !

So with this voltage tester you can trouble shoot if you battery has a bad cell and replace the bad cell ????
Excellent. I’ll need to look at it.
Price at the listed location is 51+ $.
that's a great meter to have, thanks for sharing!
WATCH OUT ALL SCAM REPLY's.
Dont whatsapp anyone replying to your comment saying you won something.
You won something! :-)

@jehugarcia what cable parts are needed for the Heltec bms with this?
Nice video. Did you try to connect this to a computer. Thanks
I bought this 3 months ago and finally used it on a 14S6P. What do you use to balance battery packs that have several cells in series like a 16S7P?
Nice cell meter china sells it all now days
There is a huge need for more plug and play bms readouts of all sizes especially for smaller packs .
Hi there for testing you can hot glue a small power bank to the back
will any inverter handle the 36 volt?
Use an Inverter designed for a 36 volt battery pack.

The aliExpress link is giving me a page set to Netherlands. I can't change to English even though I see US in pop down list.
The solution was to open link in an incognito window.
Awesome! I could use that also!
Is it possible to monitor cells in a single parallel pack, or only groups in series?
how dumb can you be offcourse not
All of the cells in a parallel pack, have the same voltage
So they are one cell
2.54mm
1/10 inch
with this meter do lifepo4 3.2 cell packs
I need a 12v 100ah battery that costs less than USD50, bro? i mean second hand battery..
Used lead asid is your only option with such budget.

I just notice he did reverse the connector.
Take an EV BATTERY, a solar inverter (PV input) and try to output usable AC
It has been done. It works.
I like the batt go better still
Enjoy and stay safe and hope that God will rap his arms around y’all and keep everyone safe and healthy member sir where no where without you!
