thank a lot mate, It is exactly what happens to my battery and no one explains it so clearly and simply. In fact, the title of the video or article is failures of the bms and they end up explaining the theory of relativity.
Thank you for showing me how to read each set of cells & their voltages via the BMS with volt meter probes! I must have toasted the BMS when I shorted live wire on power cable on positive terminal of cell group 5... Thankfully I have another BMS to swap... 🤷♂️
you prolly dont care but does any of you know a way to get back into an Instagram account? I was dumb lost the password. I would love any tricks you can give me.
@Phoenix Mekhi thanks so much for your reply. I got to the site thru google and im trying it out atm. I see it takes quite some time so I will reply here later with my results.
Better to keep one probe on N and move one probe and look for increase in increments of circa 4v. Less chance of the unpracticed hand shorting out between probe tips
i've tryed to upgrade a ridgid's battery pack by 2200mah to about 6700mah 18650 panasonic ncr18650, (2 pair for 5 in series), when i started to use a brushless drill i've had no problem when tryed a brushed tools the same battery pack stopped to work. To enable the battery i insert into owner charger and all back like before, what i have to think bms problem with the brushed tool Thank you vey much
Hey I have a 48v 13ah battery that won't power my bike , What do I do if my discharge ports are reading 21.4v but my battery charging port reads 53.4v and one cell group is drop down to 3.7v
I just installed a brand new bms on my 48 volt 13s pack, before I installed the bms, I brought all the 18650's up to 4.1 volts. I went to charge it tonight with the new bms, using one of the Luna chargers set at 100% at 3 amps. After quite some time charging, the lcd on the charger said 53.3 volts and as I was watching it all of a sudden I heard click and the charger said 54.6 volts and shut off. I checked the voltage at the charging port and it was at 53.3 volts. But I checked the battery voltage at the main output leads, and the battery was sitting at 54.0 volts!? What's going on???
Late reply fella but check each cell in that bank as sounds like 1 has dropped too low. Will have to disconnect the problem cell & trickle charge it to around 4v using a ecig battery charger then when done add it back to the pack.
I have a question. Is there a trick to testing each series without accidentally touching 2 of them at the same time with the one probe? Last time, I must had about 5 arcs that way. My battery isn't a Luna cycle pack and my bms has those pins packed so close together. Any tips?

Thankyou so much! Great video helped me so much! Ivee been trying to find information on how to do this for 3 days now!
The comments help more than a video 😊
When checking the Banks disconnect the banks Cable

@Phoenix Mekhi it worked and I now got access to my account again. I'm so happy:D
Thanks so much you saved my ass!
@Landry Zaid you are welcome xD
Thanks for posting.

Nothing wrong with BMS, it's a protection circuit. BMS triggers when plugin charge 1st time.

where to buy a new bms ?
What would you think is wrong if one bank is reading low (2.4v)
Late reply fella but check each cell in that bank as sounds like 1 has dropped too low. Will have to disconnect the problem cell & trickle charge it to around 4v using a ecig battery charger then when done add it back to the pack.
Dude, did you actually say why and how it was the bms that was faulty?
Cheers Stevie.
Can i use a 42v 2a hoverboard charger to charge my 10s 8p 36v e bike battery pack.

U need calm Fingers
can you guys advise where i can buy a stock surron bms board?
Did you ever figure this out? Looking for one as well
So, testing the cell bank voltages, then the overall battery voltage proves a working BMS then ? simples.
No proves a problem with the bms
