Summary: mower battery door removal evaluation
Background:
A couple of customers have expressed dissatisfaction with the battery door design, specifically that it cannot be locked in the open position, and therefore takes two hands. Our more senior mower operators have stated that having both hands to lift and manipulate the battery into position would be helpful.
Discussion:
One potential down side is that the battery is exposed to more dust/debris; however, this should be a non-issue as the battery is already very robustly protected from dust/debris and minor water intrusion. The attached picture shows very little dust at the bottom of the battery compartment after mowing for about 45 minutes (bagging not mulching). The mower does not have active cooling, e.g. fan drawing air into the battery like it has during cooling, therefore, the potential for sucking in additional dust/debris is pretty much minimal.
Procedure:
For the 20" Gen 1 mower, tip the mower back (storage position); let the handle down and rest it on the ground; open the battery door; remove four #3 Philips screws which retain the pivot bar clamps; remove the entire door assembly.
Pros:
Simplified design (less cost to produce mower)
Easier load/unload of battery (less operator fatigue and frustration).
Better ventilation of battery (lower operating temperature, increased longevity)
Potential for less heat retention in the motor chassis area (increased motor/system life)
Cons:
Decreased ability for mower to survive a tidal wave event
Conclusion:
Ego, evaluate pros/cons of removal of the battery door assembly from future mower models.

Why not just make the door where it will engage a simple lock when pulled up to the full open position and remain open until it is pulled back down?

The 100% solution is to make a door that stays open on its own, in my opinion. :-)

The most simple—yet somewhat unattractive—solution might be a self-stick 3m hook attached to the front of the battery cover and a cord or strap with hooks on either end to latch the door to the handle.
I wouldn’t run the mower without the cover.

I can envision people mowing with the door open and then filing warranty claims after the air intakes on the battery gets clogged with dust.

Seems like the tools that need an enclosed battery bay have them: Lawn mowers and snow blowers.

It is a matter of removing door for convenience v keeping door for possible extra protection.
Not sure that either of them are a critical need.

And if you are really concerned, then you ought to implement a process where by you "sanitize" your battery before charging, e.g. dust it off, vacuum out the vents, maybe even put it into a "clean room". Then once you've cleaned it, do you charge it in a HEPA filtered room?
The genius of Ego's battery design is how robust they made the batteries. The dust screens are pretty porous and are more likely there to prevent larger debris from getting into them, rather than trying to prevent dust from entering the battery assembly.

Of course I spend more time using my tools than trying to figure out how to modify them.

What is your theory on why Ego covers the batteries on the mowers and snow blower but nowhere else? Or why they designed it so it doesn't stay open on its own?

- Hum... I see. So much for that idea. Can you add a shim or similar object in or around the hinge somehow that would impede the free movement of the hinge and hold it where you move it to?

Mike, I'm glad one person understands my motivation, thank you.

I wonder if operating the mower without the cover voids the warranty. Seems I personally would not want to stand behind my product if it were modified to this extent.

Something a bit more substantial and better secured to the battery housing would be a great improvement for handling the battery.

Cool - I may have to get me one of these mowers :)
I can see were having to use two hands because its heavy while pressing the release button and having to hold the lid open all at the same time is problematic...

edit: Does the newer mowers have a brushless motor?

Although, for smaller hands the strap isn't a bad idea.

I see. Yeah, two hands needed for the battery with an ornery lid might make me think 'who tested this'...
Will the handle as shown be an issue when placing the battery on other devices?
