From trash to treasure: Teardown & Repair an Ego 56V 5.0Ah battery
HTML-код
- Опубликовано: 9 ноя 2024
- This one is overheated or at least that's what the charger says. Could it be a bad thermal resistor (thermistor)? Or maybe not! I'm going to tear it down and find out!
THE DROP METHOD ACTUALLY WORKS:
I was having the same issue with my 2.5V battery. I dropped 3 separate times at different angles & put it back on the charger. I came back 20 minutes later & plugged it back into my leaf blower… it started working again. This actually fixed my battery issue ❤️❤️❤️
THE BANG TRICK WORKED .SO glad I saw the comments about banging the battery from about a foot off the ground and dropping it. IT WORKED I had THREE bad batteries. ALL THREE have been working GREAT since May and I recharge and use the OFTEN. HOLY GUACAMOLE. Those three bad ones were here for over a year. I bought two news ones for 200 bucks a piece but something told me NOT to throw those bad ones out. THREE bad batteries now working PERFECTLY for five months with CONSTANT charging. I have the lawn mower, leaf blower and snow blower and I use the blower daily and the lawn mower once per week. HUGE area. SO glad I was the comments about BANGING the batteries. THANK YOU THANK YOU THANK YOU
Explain this please. Or link bideo
@@bigkk758 Very simple. Hold the battery in your hands at about waist level. Drop it on the ground, like a sidewalk. That's it!
@tonys4396
Are you dropping in a particular side of the battery housing, or flat on the top, flat on the bottom where the charger connects... it's there a specific way?
@@LarryMusgrave One I dropped from waist heighht. straight down. Another I held in hand and smacked against the sidewalk while holding it on the top corner. Just hit it any old way. it worked for three of mine. I wasn't careful because I thought they were going in the garbage,
That actually worked
The one piece of advice I'd give all ego customers is this: register your batteries!! They have a good 3 year warranty if you register them, and they are very good at replacing batteries that have started losing their ability to hold a charge. I just replaced a 2.5ah, a 5ah and a 10ah battery, and all I had to do was call EGO and tell them they weren't holding a charge any more and they sent me three brand new batteries. They would have cost me about $900 or so, so that's a great deal. Now I'm set for at least another 2-3 years, and before the warranty on the new batteries goes out of date, I'll replace those as well. So now I have new batteries and the old ones as backups. REGISTER YOUR EGO EQUIPMENT AND BATTERIES!
This is good to hear. Thank you.
Ego just told me they don’t put another 3 year warranty in replacement batteries. The warranty is still only based on your original purchase date. Pretty bummed because my replacement battery just died as well. And they won’t honor the additional 3 year battery warranty
the battery is too expensive to replace over the year it costs much more than the strimmer itself. Not for me unless I know I can rebuild the battery for less by myself.
Wish I knew this
@@baymaxhero4127 I would have never done it either, it's my wife that is fanatical about warranty registrations, and it's saved our bacon on numerous occasions.
I pulled my 7.5A/h pack apart as it would start to charge then stop and the charger would switch off. After pulling it apart I noticed the terminals were really dirty. So I carefully cleaned then and batts looked to be OK so reassembled and now its working perfectly! Thanks for showing me how to get it apart and test.
Dude, the stuff that is encasing the BMS actually comes off fairly easy on some of the batteries. Fuse on the larger batteries are bigger too. Man your vids inspire me to make more vids!
Not on this one. If I try to peel off that silicone, all of the electronics will come out too.
@@vuaeco
I have a video from over 5 years ago showing how easy the silicone potting on this BMS is to remove. It was my very first EGO repair video. These 5ah and larger have a temp. monitoring board in the middle of the pack halves with smd transistors. Hope it helps.

@@vuaeco interesting, the one I took apart was super easy to get the silicone out.
@@vuaecosame. I’m working on a 4ah one now and the silicone just won’t come out. It chunks out in little pieces. Took me over an hour to get it only half way uncovered
It looks like epoxy. Impossible to remove.
Thank You! Thank You! You and your knowledge were very valuable to me. You are the reason I love and enjoy RUclips!😍
I had the same problem with the same EGO 56v 5Ah battery. The red, non flashing "overheat' light remained on and it would not charge, even hours after the battery was at room temp. I put the battery in a ziplock bag and put it in the freezer overnight. Next day, I let it warm up to room temp inside the ziplock bag after I removed it from the freezer so condensation would not form inside the battery. It now works & charges.
Excellent video. Diagnosed to find the culprit is what it is all about.
Is this guy have an Asian/southern accent? It’s almost like there is a southern Georgia gentleman hidden inside of this Asian technician who is sneaking out to speak every once in a while.😂😂
When i had this issue, i dropped it on the floor about 1 foot off the ground.... it fixed the issue 🤣 . Found that fix from a comment on reddit, and Apparently its worked for many people. For a product so expensive, these batteries are built pretty cheaply.
Also found out when attempting to replace one of my dead batteries, EGO had the info for the warrenty on file, but because they didn't have a copy of the reciept on the dead one, they would not honor it, even though they acknowledged i purchased it as a new product. They said it was up to me to find my two+ year old receipt. Rethinking about staying with EGO. Really ticked me off.
Yeah they suck. Im staying away from flex bc of my ego warranty BS. Milwaukee honors by mfr date. It also explains their high resell value. Ill stick w ego for yard stuff, but no way im replacing m18 for flex.
same, but I had the receipt in the booklet. I scanned a different receipt from the same store. they had my info on file too. I sent them a picture of the original mower receipt, so hopefully I'm good. 10 days left on my Battery warranty 😱
I had the same issue just last week. The blower was a gift and I had never gotten a receipt. After much haggling, they sent a new battery, but said it would not be covered under warranty if I did not have the receipt. Really dumb since they have the manufacture date and know the battery was still in warranty. Products are great until you need to get warranty replacements.
Mine was the termistor. Thank you! 🎉
I love your accent. You sound foreign and learned English in Mississippi. Lol
Keep at it!
I think he is Vietnamese because my accent is the same as he. LOL
Definitely sounds Vietnamese
Yes you can remove the circuit board. I've done it. Peel off the gdet silicone and there's philios screw underneath
Such a good and helpful video!
Thank you for the information!
My ego is 10ah version
Thank you for your video. Where can you buy individual battery cell?
You explain things really well thank you!
P.S. On a crank sensor (red / black / blue wires) how do I check the polarity of the red and black - is it OK to just swap over and see if it works?
Do you mean the cadence sensor for the pedal assist? Usually red is positive 5V (for most sensors), black is ground, and the third wire is variable voltage for sensor. This is exactly the same as the throttle cable. I think you can swap it with a throttle control and it should work but don't blame me if you burn your controller because I've never tried that before. I'm just guessing. :D
@@vuaeco Ha no problem thank you!
I have about three dead EGO batteries. Do you offer a repair service. I'd be happy to send them out
Hello and Thanks, have you had any luck finding matching BMS boards on AliExpress or other places?
Excellent video. Thanks
This was very useful for me. Thanks
Very good video!
Hi Where do you buy the battery for replacment? Thanks
Where can one purchase a (used) 2.5Ah controller or bms? I have a battery with good cells but it wont charge. Thanks
so my battery checks out fine in this voltage method but my temp resistors read 12.18 and 12.09 are they ok my charger turns off and on when charging from red to green light i have 2 chargers both do it but not all the time somedays it will charge but last about half as long im at a loss now any ideas
I accidentally pulled out the connector wiring I need a picture of the wiring 5.0
Opened up my battery unplugged everything. Plugged it back in and it started working again
Nothing was repaired but just disassembled.
Awesome very informative. Learned a lot thank you
This was a very informative video. Your English is very good, but your accent takes a bit of getting used to. Vietnamese? Anyway, thank you for the video and keep at it!
I have a brand new 5.0 AH Ego battery the board went bad………….The cells are all Ok, I was thinking of attaching that battery to a working 2.5 ah battery; connecting ( Positive & Negative) terminals tapping the two batteries together……That would make the battery 7.5 ah battery, you think the board on that 2.5 ah battery could handle it????????????????
I would guess that it would NOT handle it. Even with swapable BMS boards like Kobalt, each likely has calibration parameters programmed in it for the cells that come in the pack.
I am going to guess that the people who hsve had success dropping the battery are just causing the connectors to move slightly and then make a better contact.
I hsve tried smacking the battery without luck.
Putting them in the refridgetator for a few hours worked once or twice.
I had one battery that would not charge, i put it in my blower and tried to start it..
If i could get it to run fot a few seconds , then putting the battery on the charger would give a normal charger
However the capacity was nowhere near normal
🔥📈🧠
So why do the volts add up in increments like that? 3:49 Thanks
Series and parallel !!!
The batteries are in series. 1st battery (3.3v) contact positive side to negative side of second battery (also 3.3v) will read 6.6v. This is called series connection. Ego use 14 x 4.2v batteries (charged to 4v each) soooooooooo..... 14 x batteries at 4v each. Connected in series 14 x 4 = 56v
I have one of these EGO batteries on my leaf blower. After watching this video, I would not buy another one of these products. What did you decide to do? I assume you tore it apart to use the cells, but these products are so damn expensive to begin with.
I don't have another 5Ah Ego battery so I'll just wait for another dumpster dive and pray to God it has a dead Ego 5Ah battery inside! :D These are good cells so I'm thinking reusing them for my ebike.
Yeah, you can tell these were designed to fail, or at least designed so when (not if) they fail you have to purchase new. I don't play with companies like that.
I've had good luck with the third party batteries on Amazon. The Tomapex 5Ah worked just as well for a much lower price.
@@DerekWoolverton Thanks. I'll check it out!
Holy shit Video
Run out my second battery, these are truly BS products going back to gas so I don't have to deal with their headache.
At the end of the video you said "so that's how you repair or salvage" but you did not repair anything.
...no...he did not. BUT, he did explain it
He showed the steps necessary to repair if it was a cell or thermistor. Even a board if it's the same size with the right connectors.
I'm thinking a gas powered tool would avoid all the electrical issues.
As the electric would avoid any mechanical issues. Comes down to personal perference
Registering your batteries will not BE COVERED under warranty UNLESS you bought at their stores they say go to. I have several items they were given to me as a gift and EGO refused to cover under warranty. TERRIBLE CUSTOMER SERVICE.

DIY Home disassembly of lithium ion battery packs should not be encourage watching videos like this , fire and explosions are danger to others causing injury and deaths.
That's not necessarily true. If you're mechanically inclined, not an idiot, just use some caution and be careful using metal tools around the battery Cells and it can be done safely.
The other option is the entire Battery will be put into the landfill
We let people change their own break pads on a car!
Ur lame! Change a fuel pump,oh god so dangerous. Change a break, oh you could die. Making beer at home with co2, oh you could auffocate. Seriously, all diy is dangerous. Just buy new stuff and pay pros since life is so scary.
Learn the theory of what youre working on and proceed understanding actual hazards. Build your knowledge and skill set.
Thank you very much for the video.
Oh please, just because you dont understand them enough to work on them safely doesnt mean others cant.
They are not complicated.
@@caseygina3553 you dont need a fraction of the 60v to stop the heart. Voltage isnt whats scary, its A. A taser is safe due to lower Amp.
He said repair or salvage.
