Ego CSX5000 big battery test. Does it matter? Cordless chainsaw with 12ah battery on 22 inch oak log

#cordlesschainsaw #farmandranch #tools
It does make a difference, but not what I expected. More testing to follow.

[@maxmannsperger2816]

Very interesting! Now i would like to see the compairison with the 8Ah Greenworks. Considering the price gap between both saws, its seems to me, that the greenworks is the better deal. Nice test als alway. Thx

[@reusefull]

I have already done the comparison! I'm just trying to get the video together 👍

[@John-cj3ve]

So...I ran MY 12ah test; with a 20" bar, and a brand new full chisel chain... Yes; my battery overheated too. BUT! I got over twice as many cuts; 7 1/2 in a 22" white oak log; before it overheated and stopped the saw. Right now I have the battery sandwiched in between two 4" cooling fans. I was able to check the capacity just now; and there are two segments left. Better than a sharp stick in the eye I guess.

[@reusefull]

I got 7 and change cuts also... what's the date of manufacture on your battery? Mine is November of 22, so I was wondering if you might get better results. Also, how hot was the saw motor? I took the chain guard off and the drive shaft from the motor was very hot.

[@John-cj3ve]

​@reusefull mine is November 22 as well. Curiously; when the battery arrived; it was showing 2 solid segments; and took 90 minutes to charge on the 5500. This time it was showing 1 solid, and the second one blinking when I put it on the charger. Yet; it only took 45 minutes to fully charge!🤔

[@madatu247]

Big money, but I'd be curious how the 28AH ego commercial backpack battery would work?

[@CA34562]

Can you cycle between the batteries to prevent downtime? - Run the 8amp for 6 cuts till it overheats the battery. - then switch the battery over to the 12 amp and make 7 cuts. - then when it over heats switch back to the 8 amp that hopefully had enough time to cool down and see how many cuts you get? - then just keep switching back and forth as they over heat? As i assume its not the chainsaw thats overheating, only the batteries? I'd be interested to see you test this in a video.

[@reusefull]

I ran the 8ah battery for a couple cuts, but I was nervous because the saw drive shaft from the motor felt pretty hot. I guess I should just run it and then try the warranty if it fails and let everyone know about that as well. 👍

[@CA34562]

@@reusefull Fair enough. Maybe switch it back to the default 20" ego bar and chain and re run the tests. Looks like you discovered why it doesn't come with a 3/8 by default. But it would be interesting to see if the same issues arise when nothings modified..?

[@John-cj3ve]

I think I will be able to use it on a project/tree. Because of my depth of EGO products; I have the 12, as well as the 8, plus two 7.5s. One would think that having four batteries, (I have tested the saw with the 7.5; and it DOES run it at full power); you would be able to; as you say; cycle through the batteries enough to keep the saw running. Unless; as reusefull noted; the saw itself gets too hot.

[@reusefull]

@CA34562 I'll give that a try, but the funny thing is, the CS2000 and CS1800 come with 3/8 chains. I know the 24 inch bar and chain definitely works the saw more, but it was odd that this saw was .325 when the others are 3/8. Same with Greenworks I think.

[@CA34562]

@@reusefull likely because the cs2000 and cs1800 has a lower power output. So it’s not producing as much heat to be an issue. If you run the csx5000 on speed 2 itll probably be the same as running the cs2000 on max. I don’t doubt that the reason the csx5000 has a .325 and not a 3/8 is because they found out just like you did in your tests.. that it overheats the batteries too quickly. So they used the smaller chain to try and get around it. I seen a video of the stihl msa300, and that one also had issues with overheating. So it seems there’s a real struggle with all high powered battery chainsaws and heat. Still a great saw if you only use it on the odd occasion for small durations. But gas still wins out for all day use it seems.

[@John-cj3ve]

Hey! I've got ANOTHER Idea for testing this CSX5000! Given that the saw is pretty powerful in the first place; would you please do a runtime test for BOTH batteries at low and medium speed? Maybe the batteries won't cook; or at least give a considerable longer runtime before they do. I would do the test myself; but I don't have that much wood left. I have to wait until a tree service drops some off.

[@reusefull]

I definitely want to do something along those lines. These tests are just torture tests... not how I would normally cut anyway. I was also thinking of comparing the Ego commercial to the CS2000 to see how much more you're getting on the CSX5000.

[@John-cj3ve]

I just saw a video where a guy cut up a rather large poplar trunk with a CS2000; and he cut the entire trunk on high speed; and the saw never shut off on him.

[@reusefull]

@John-cj3ve maybe it's the same motor and they're just asking too much of it with 30m/s. I think the CS2000 is 25m/s max.

[@John-cj3ve]

You are correct about the max speed of the CS2000. That's why I think the test at low and medium speed should turn out much more favorable. Idk how fast the low and medium speeds are though.

[@jean-marcbriane7283]

@@John-cj3ve According to the characteristics: low speed 20 m/s, medium speed 25 m/s

[@John-cj3ve]

...as far as runtime goes; I'd be interested to see if the runtime is greatly increased with the original bar and chain. That should be an overall decrease in demand for power compared to the 24" bar. Looking for a positive here...

[@reusefull]

Right. Maybe the battery won't overheat. The motor got very hot too though, which I find concerning.

[@joshspohn4613]

The thinner the bar/chain. The faster it will cut make sense to me

[@benjaminleslie3155]

Also now that you have that 8.0 and 12.0 you might as well buy the ego inverter to make them worth it.

[@John-cj3ve]

That IS something to consider.

[@jean-marcbriane7283]

I think it is better to use the original saw with 20cm guide and 6 to 8ah battery. If we increase the guide and large battery, the chainsaw becomes very heavy?

[@reusefull]

Definitely, but the 20 inch guide didn't reach through the log😂

[@jean-marcbriane7283]

@@reusefull We don't cut trunks over 50cm every day.

[@John-cj3ve]

I've watched so many of your videos; that I can't remember which one has the comment about the cell size being different between the 10ah and the 12ah. Has that been determined to be true? If so; maybe the 10ah would be the way to go.

[@bizzarko]

Put on eco and low speed I get way more cuts

[@benjaminleslie3155]

That saw has a centrifugal clutch correct? If so then that would be where the heat is generating from. I wonder if outboard clutch is the better option for battery saws.

[@reusefull]

There is no clutch that I know of

[@benjaminleslie3155]

Ah, ok I wasn't sure if it did or not.

[@sanjaygupta666]

Just used my brand new CSX5000 for a couple of minutes when it was cutting beautifully, after which it started to burn the wood blowing smoke & wasn’t cutting. Spent over an hour trying to find the exact cause/problem - seems the chain they supply is junk with low grade metals.. It goes very slack when hot, then tightens when cooling down. Pretty angry. Will refund under their 30 day return policy

[@reusefull]

I guess I really only ran the supplied chain for a few cuts. I've been using Oregon EXL series chain for most of these tests. That's disappointing for sure.

[@pd-cr7sb]

Isn't that standard? Heats up with use and expands, the contracts when cooled down. Also, I know it's a new chain, but does it need sharpening?

[@John-cj3ve]

​@@reusefullI performed the great sin; and touched the ground with the original chain; which rendered it useless. I haven't taken the time to sharpen it yet; so I replaced it with an '8TEN' full chisel; which seems to work well.

[@reusefull]

What speed is your oiling set at? Was the oiling working like it should? If it's a new sharp chain, it sounds like oiling is suspect. If not, maybe the chain hit something in the wood and dulled up, then started to get hot, not cutting well.

[@John-cj3ve]

How EXTREMELY disappointing! I just wasted 600.00 on a battery that's not going to do me any good! I was satisfied with the power of the saw with the original battery. What I was looking for was extended runtime. How come the 'math' didn't work out? If less current is being demanded from each cell; what is generating the heat?

[@reusefull]

I'm not sure. Maybe your battery will have newer better cells and you'll have a different result. It was really puzzling to me that the battery didn't weigh more. I would think it should be pretty straightforward in those terms. I did get a little bit more power and quicker cuts. I really believe that if I back off the saw a little bit that I might get better results. Like I said, I think the feature that makes the saw more enjoying to use (not stalling) is probably why the batteries can overheat.

[@BenDiscoe]

FWIW, my experience with heavy use of a big battery chainsaw, extended runtime is better from having multiple batteries, not a single bigger/heavier battery. Still expensive, but a different expense.

[@John-cj3ve]

​@BenDiscoe after going through this experience with my horribly expensive 12ah EGO battery; what you say makes perfect sense. However; it would appear that from the tests that reusefull has done with Greenworks batteries; the same logic doesn't hold true for them.

[@BenDiscoe]

@John-cj3ve Yes he's seen a bit more power from the 82cs34 by using the 8Ah over the 5Ah, but in my experience the 5Ah already goes hard enough, lasts long enough, and is difficult to overheat. Having more spare 5Ah, in my opinion, is nicer than having a smaller number of heavier, more expensive 8Ah.

[@John-cj3ve]

​@BenDiscoe I don't think that the CSX5000 is ready for market. It feels like we're part of the development team; at our expense!

[@John-cj3ve]

...oh joy; my waste of money is arriving in today's mail 🤬

[@ElectricDanielBoone]

More Ah (amp x hours) increases run time not power. You may get tricked as you go up in ah because other things got changed besides just the ah rating. Things like bigger output wires, higher amp fuses, heavier circuitry, ect, but more ah doesn’t increase a saw’s/battery’s ability to take a heavier load on its own.

[@reusefull]

I was thinking that Ego would follow suit with Greenworks. The Greenworks 8ah (82v) battery definitely pushes more current. There is a chart that gives the ratings, and I've observed it. What you said is definitely logical... if the wires/fuses/circuitry are not bigger, they can't pass more current regardless of availability from battery setup. 🤔

[@ElectricDanielBoone]

@@reusefull Yes, GW had to be changing other things besides ah to get more peak power out of a pack. Dang batteries are way more complex than I realized! I was looking at the difference between GW 80v and 82v and how can 82v make any real difference. Turns out running with an extra 2v is pretty difficult as that puts the cells right at their max voltage of 4.2v and is very close to overcharging them, which is kinda dangerous. It seems a lot more attention has to be given to matching cells and to the BMS to keep the pack alive for an acceptable time when they’re on the upper edge like that. It seems to me at 82v it’d be even more important to store packs better. Time and temperature aren’t good for battery packs (cells). Maybe check the date of manufacture when you get a new battery and send it back if it has been on the self for a few years.

[@John-cj3ve]

​@ElectricDanielBoone what about the fact that there are more cells in the 12ah compared to the 8ah? Wouldn't the load being distributed across the larger number of cells make the battery run cooler for a given draw?

[@ElectricDanielBoone]

@@John-cj3ve probably, but what is being measured to trip the battery off line? I’m thinking more than just battery temp is being monitored.

[@John-cj3ve]

​​@ElectricDanielBoone who can really say? However; the saw will NOT run again with THAT battery; until it has cooled down. The saw WILL run right away with the installation of a new battery; until THAT one overheats.
