I was hoping to learn how to replace a faulty cell, but instead we got a half-hearted video on how to completely fuck it up. Well, we all know how to do that.
Hi! Like the title says, this video is about a teardown not a repair. Some of the components were destroyed but some other components can, and will, be used in other projects. Maybe, someone, with the same faulty battery, after seeing this video could take a different approach and effectively repair the battery. Thank you for your comment!
@@LegendaryUrbanHackerZ do a tear down on stihl cordless chain saw. i would love to see the motor and compoenent inside.
I dropped my EP 300 and it doesn’t work now it blinks three times when I try to power it or charge it. Does still have a replacement program or warranty when you buy the batteries?
How to get the front plate with BMS separated from the front of the pack? I have a different model but it looks similar. Shell removed but front plate is not budging from the pack. Looks like it might have some epoxy holding it in place on my model and I don’t want to tear the plastic up to access the board.
Hi, Can you please tell the IC number, not just the MCU but the other main ones. I am working on something similar and want to know what Analog Front End (AFE) chip this BMS is using. Thanks
Hi! I´m very sorry but i have deposit the board in the recycling center with other stuff so i cannot search the information you want. On other hand, i remember that at least one other IC had no marking... All the best!
:( Thanks anyway
Thanks for the teardown. I own a defective AR3000 with fine cells. I disconnected the BMS in order to reset it but now there is no life on it. I think it must be initialized. On other batteries, the scope (between green and yellow communication wires) shows signal like a 9600bps RS232 communication between the tool and battery. Do someone knows a place to grab informations on the communication protocol or the Stihl BMS reset ? Thanks
Bonjour Sébastien, Tu as trouvé une réponse à ta question ? Je suis dans le même cas....
Have you solved the problem ???
I too am a proud owner of an AR3000.
I got it for cheap at an auction because it wouldn't charge anymore.
I opened it up and charged the cells directly so now it shows half full when I press the button on the battery pack.
I don't have the connection cable or a charger for it. The connector is called a speakon connector, usually used for speakers.
There are 4 cables going to the connector, red and black for power but also a green and yellow wire for some kind of communication. I'd love to use this battery for some projects but I can't get it to work sadly.
Hi, what is the purpose of the two slots in the middle of the battery. Can the chainsaw work with an external diy +/-36v battery pack ?
georgilisev Hi i'm interessed.
Hello, do you find a solution to adapt any 36V battery on Stihl garden tool ? Thank you
2 central pins (green and yellow wires) are TX and RX pins for communication between tool and battery. That's why you cannot just feed 36v from external power source (tool won't start).
@@ssd8339 It would be nice that we could make a bridge in the toold, then make a backpack diy battery with 18650cells, 10s5p 36v 15Ah for example, with a Battery Management System like those used in ebike batteries. I do not find information about it
Got a ap200 few months back dropped it last week and now its not working
Any ideas what it cud be
SAME PROBLEM
I have a dead stihl battery can i change the cells easy ? or is that too much work ?
I think it will not be easy to replace a dead cell in the Stihl AP 80 Lithium-Ion Battery. To know who is the dead cell you have to dismantle the battery. After identifying the battery you have to remove it and solder a new one in that their place. Possible but difficult. I would suggest save the good cells for other projects. Thank you for your question!
I need to know which of the wires (Blue, Black) is negative and which is positive. Do you know?
The Stihl AP 80 Lithium-Ion Battery was fully dismantled long time ago. I don't remember that detail. Sorry!
Black = _ and blue = +
@@greenthumb7086 Which is fucking logical ))
can i connect my msa140c to a power supply and use without battery
No because stihl use a communication protocol between battery and tool... So you won't be able to run the tool by only feeding it with 36v from external battery or external power supply.
It seems to be a simple RS232 communication but didn't find any work on this yet.
This was the 1st time I saw on PCB with melted plastic on top, probably would heat sink function.
And YES, the chemical batteries are dangerous, thanks for the video,
continua curioso :)
+G7Dropes The melted plastic protects the PCB from the surrounding environment. This battery was removed from professional gardening equipment... (subject to water, mechanical shock,...). This method it is called "Potting" . In this method one liquid potting compound is poured in the case/PCB covering all and completely encasing it. In the other hand, the most usual method is "Conformal Coating". You can search on Google for more info!
+Legendary Urban Hacker
Interesting ... by chance did not know the technical name of "Conformal Coating", I have seen some devices with a black epoxy, but not transparent; It is pretty transparent but to repair no longer be.
Sorry for my English
I think my charger might have died.... I have 2 180's and both do nothing when plugged into the charger
What kind of 18650 batteries are they? Are they Samsung or sony batteries?
There is no brand on it. If it helps they have printed SE US18650VT and T T1122QK11V.
SE US is Sony battery.
@@LegendaryUrbanHackerZ the brand is Sony. But what is the number after VT? 3, 4, 5 or 6?
@@polinaterzieva7460
It's just VT, an 1100mAh cell.
🔋🔬
Had one fail after less than a 100 cycles , was just out of warranty.No rough handling . Had to stump up $250 for a replacement .Pissed.
Is it was just enough to swap batteries or it was needed some short off programing/pairing of new battery? Or it just worked at once?
Hello,
thank you for the video.
Do you know if it is possible to use a 36V E bike lithium battery to power a stihl equipement, making a diy adaptator to link the + and - of my e bike battery to a stihl equipment as fsa90 or fsa 130 ?
Magnet genius
I've got into the video 7 minutes I'm looking at somone who won't spend a few quid on anti tamper torx screwdrivers, I'm finding it hard to take him serious as an engineer I should follow for advice. I'm watch some more but in sceptical he knows what he's doing?
Hello please answer on my question on AP 180 all 4 light is red what that means ?
Hello,
If you have Voltage on the battery above 36V the problem is on BMS board. I have now the same problem, I do regeneration on battery because voltage per cell is approx. 2V now is 38,5V wait for the charger to finish it but the charger flashing 10 red lights. And I can't find solution (reset BMS or change board chip or what...)
Hello, did you find any solution? Four red lights flashing, connected with another ap battery to revive but nothing.

Yeah cheers UA-cam! Just cut the sound. Because of copyright no doubt. Ah those poor starving musician's yeah brilliant! Don't think about your partners do you? No not those people who take the time to film edit and then upload onto your platform.
You don't have to wear gloves to carry out such sabotage.
Don't even try opening any lithium battery without proper tools and some electrical knowledge. Very dangerous business
