EGO 56V Battery Cell Replaced

Anyone who uses bad language in my comments will be deleted. Don't waste your time. We can very easily express ourselves completely without the need of that.

Excellent. Thank you. Finally a video that clearly shows the phase change material

Thanks for the videos. I have some older EGO products, NO experience with electronics and no repair facilities near me so I will be using your videos alot. Thanks again

While I don't have confidence in sauntering batteries. You gave me the idea on a solution and much respect for the time you've put in

I accidently found a quickway to solder. If you use bevel tip and apply a little bit of tip tinning solder first on the bare steel then soldering will be a breeze. That's what i ended up doing when soldering those 10 awg bare wire to the cells' strip. That was very quick and didn't overheat plastic underneath. Thanks for the teachings.... helped me out.

Thanks for the video , excellent , clear and precise. Subscribed!

Thank you for information . I will keep on watching.

Thank you for your vid. That's a ton of work and know how. I wish EGO would make these packs so we could EASILY replace the individual cells like replacing flash light cells.

I'm glad you addressed the flux at the end. I wondered why you weren't using it.

Thank you for the great informative video! I know now that I won’t be repairing my ego batteries when they fail. I’m pretty handy repairing appliance’s and other equipment and I think I’ll pass on cell replacement. Did like your fuse repair on your 5ah Ego video repair!

your patience is very commendable. I don’t have the time to repair my Ego batteries. I like the tools, but the batteries have been a disappointment. My, even new batteries act strange, and after a full charge, may flash red for no reason. 5ah battery , sitting on the shelf, sometimes heats up the lights turn red. And, I am not rough on my tools; they are treated with kid gloves. These batteries cost more than my first car, and are way too expensive to behave so badly. Will be scraping Ego tools and go with Lowe’s Kobalt. Less cost for competitive performance. Fed up with expensive equipment that doesn’t operate correctly.

Nice catch at 6:07! Not your first rodeo obviously. Very informative video.

Great video!

Very nice video. Thank you.

When you recycle your cells, rip the tabs off the bad cells, but keep them welded to the good cells. Your recycled cells will then have tabs that can be soldered to directly. Then just solder tab to tab into the pack. This way avoids soldering directly on the cell, and the the heat that would pass into the cell. I repaired my an ebike battery with this method, when the last cell group failed. It worked great. I soldered a heavy copper wire in parallel to each tab, then in serial to the rest of the battery. No cell was soldered directly.

Very informative video. Cell balancing is important. All 14 cells get the same charging current , and all get the same discharge current. If you install a fully charged cell among 13 nearly drained cells then this cell will will get overcharged during a battery charge cycle which could be explosive for that installed cell! Likewise installing a drained cell among 13 fully charged cells and using the battery in a tool will drain this cell excessively to failure ( charging it in reverse polarity). With another 14 cells in parallel (in 5 Ah battery) even more issues occur. The installed drained cell will immediately get charged by the the second set of charged cells (but again overcharging the 13 other fully charged cells). I can only hope the BMS circuit should help correct or detect some of these cell balancing issues. A protective circuit inside each cell is another helpful thing. NiMh cells can cause fires if over charging or excessive draining to reverse polarity.

At time marker 2:35 you are able to pry the plastic housing apart enough to slip the bad battery out of the black plastic holder. I had no luck with that process. I worked at it for a while and eventually ended up breaking the plastic holder. Which wasn't the end of the world as I could reassemble it with the screws. It seems like the contact strips are welded on AFTER the batteries are put into the plastic holders. This means that in order to properly service these, it might be necessary to take all the metal strips off of at least one side of the pack and reattached them after battery replacement. This is a disappointing amount of work, but might still be worth it to get the pack working again.

Glad I saw your videos, Looks Like I almost fell into the EGO trap, of Battery short Life. I think Ill hold off buy anything EGO, since the Battery Life is Not very long, If their Battery warranty was 3 years I would consider them

@thrifty Tool Shed Please do you know in batteries (BA1120E/BA2240E/BA3360E) which type of cell is used ?

This is a great video! Just what I was looking for. I’ll try the same repair. Maybe use a 40 amp? I replaced the soldered fuses on the SNT2100 snowblower, adding replaceable fuses and had to go to MAXI fuses to do 60 amp. So I’m wondering if the battery fuse should match these??
