If I run it at 16 watts, I highly doubt it. I'm sure that I'll get over a days worth of battery life. I'm going to try it when I get my board. Just like anything from evolv, this board will be very efficient.

I agree, it's very likely there are designs already finished and will be ready for sale the moment the board is released.
But not everybody can afford a $100 printed enclosure...
btw that resin molding smith job looks very expensive for retail production,
just saying.
I'm speculating here, but if I were starting with the premise of a 3S battery, I'd use a buck-only regulator architecture because it can be somewhat more efficient than the buck-boost architecture you'd need to run from a single cell.
I rather doubt that Evolv has gone to full open source.
Oh, I hadn't thought of that! Yeah, if you went to a single 18650, you likely (very, very likely) wouldn't have access to anything over 4.2v minus voltage drop/battery sag. Basically, anything a dna 30 COULDN'T do, that's all that a 1s would be ABLE to do. They are almost certainly using buck only, as that is, like you said, usually more efficient.
Yeah, I did't think they'd go full open source, but it sort of sounded like it from some descriptions.
You can always design your own with Tinkercad.com...that cuts down the middle man and lowers the print costs.
I'd much rather that Evolv sell those custom enclosures...mmm hm.
Just wondering what they are...cast zinc alloy or aluminum alloy?
They clearly went to an awful lot of trouble to design and make them themselves, so they might actually be preparing to market them?
Don't think that they'd just make them for the betas, but maybe?
According to at least one beta...most got the "rough" ones, but at least one other got a much more refined one.
So it leads me to believe that they might be preparing to offer them for sale?

I pretty much addressed the problem of such thinking in my post. You have to compromise to make a better product. If making the board 200W-capable means that it needs to be larger & the mod needs to house 3 batteries, which caters to 1% of users, then you're making it a worse experience for the majority and losing potential customers (me for example).
I didn't feel like posting the video of a high drain imr being hard shorted and shooting across the table like a scud missile, because we all know that it's a possibility of imr's, they don't always "get a bit warm and harmlessly vent gas" as forwarded in this thread.
Li-po batteries have been used in the rc world for awhile now.... How many news stories have you seen..."battery in kids toy explodes, parents be warned of danger from li-po batteries"
All batteries have an inherent danger, but nearly always brought on by user error. Just like imr's when sub ohming started becoming a thing, it's up to the user to educate themselves about the do's and don'ts of what they are using. What is our reply when sooner one posts about a mech exploding? "what did the user do?" It's no different with s li-po. Sure, some bone heads will cause damage with them now and then... They already are with these "safe" imr's, but give more credit to the average modder, far more are doing it right, or reported accidents would be much higher
It's funny you keep babbling on about people not understanding current LiPo tech when you clearly have no idea regarding current hybrid battery tech.
They have a machine shop in-house, but have said it's not a really advanced one and not good enough for mass production. So I assume they made the BETA enclosures in house and will only sell the board when retail time comes around.
As for people complaining about the size, it's hard to tell without a frame of reference, but the pics make the mod look rather small, imo. I assume it's because of the Li-po packs, which I think will be the standard in most mods in the near future (and yes, I realize other companies are already using them).
Coming from the guy who thinks a 5c lipo is suitable for a 200 watt mod?
I've not babbled about "understanding lipo tech" I have been pointing out the irrational fear of the tech, a big difference. Nothing in my posts would indicate a lack of understanding of hybrid imr's. If you think they will always vent safely, go ahead and vape on happily unaware of the possible risk. But fear mongering about something you have proven to not know about does no one any good.
Sent with one hand, the other is busy vaping.

Now you're poorly attempting to put words into my mouth? Or you're having issues reading usernames?
There are pictures and videos all over the place of vented HE2s and 25Rs, they're neither exploding nor going up in flames.
Meanwhile check what batteries are found in all the fixed battery devices that are burning up and in some cases setting people's houses on fire.
Real world experience doesn't seem to agree with you.
One can hope, but given John's comments in the past about Evolv not being good at cases I have my doubts.
Sigh... how many times does it need to be said? It doesn't NEED to be larger. You don't NEED 3 batteries to use this board. A 3S Lithium Polymer battery will work, too. Look at the picture of the beta test rig. It's pretty small, and could be made even smaller with a different LiPo in it. LiPo's come in all shapes and sizes. LiPo's are the future, you can get just as many C's and mAh and take up a lot less space than if you were using 18650's. Think about it like this: Everyone raves about how great Sony VTCX's are, how great Samsung 25R's are, but a good LiPo puts any of those to shame. Not saying that those are bad cells,,,I love Samsungs 25R's and 30Q's, but my 1800mAh LiPo in my Hana v4m lasts longer than either of them. This unwarranted LiPo-phobia really needs to stop. Yes, they can vent and explode. ANY battery can vent and explode. Your friggin car battery can explode, it happens quite often, believe it or not. If anyone is afraid of thermal runaway, maybe you should refrain from vaping. Or using a cell phone, for that matter.
I dunno...this looks pretty clean to me.
I'm not familiar with a metal-print but on close inspection it's clearly a custom made something?
omg ALL? SERIOUSLY? Holy cheese whizz on a cracker, Batman! We're in a lot more danger than we thought!
I'm putting words in your mouth? You didn't reply to this post...
Whatever, I'm not here for a pissing contest. Think what you wish, I'll continue using lipos and combat misinformation about them when encountered.
For those able to see objectively.... Factor in the sheer number of lipo batteries in the market..... The accident rate drops to a pretty miniscule amount, and those mostly user error. Don't allow others to steer you away from very capable equipment, research and decide for yourself if its good for you.
... With this post...
Now poke it with a stick.
