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.

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.

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 Now I'm set for at least another 2-3 years, and before the warranty on the new batteries goes out of date, I'll replace those as well.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!

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.

Hello and Thanks, have you had any luck finding matching BMS boards on AliExpress or other places?

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.

Hi Where do you buy the battery for replacment? Thanks

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?

@vuaeco

11 ай бұрын

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

Awesome very informative. Learned a lot thank you

Opened up my battery unplugged everything. Plugged it back in and it started working again

I accidentally pulled out the connector wiring I need a picture of the wiring 5.0

🔥📈🧠

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 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

Nothing was repaired but just disassembled.

So why do the volts add up in increments like that? 3:49 Thanks

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
