Yeah, you could use a 4cell LiFe, but you would have to charge with a separate charger and use a JST connector with some resistors I think to allow the board to operate. And LiFe's stabilize at 3.2v during discharge and spend most of their useful charge life at that voltage. So with 3cell that would be 9.6v or 4cell would be 12.8v during most of its operation. Sounds like it would operate the board fine at those levels. Mike said the LiFe LVC is 2.84v, and a 3cell Life would cutoff at 8.52v (would not be an issue for a 4cell LiFe), so I'm not sure how that would work out since the boards operating range is 9v to 16v. Maybe the 9v is lowered a bit if LiFe batteries are used? I don't have the answer to that and will have to wait for others with more knowledge of the board for an answer. In a real use case, LiFes drop very rapidly from 3.2v at the end of a discharge so that it probably wouldn't matter is the LVC was 3.0 (to keep minimum 9.0v for board operation) or 2.84. That 0.16v difference would happen too quickly to be an issue.
why dont you just ask it on the DNA200 forum. Evolv would be the best people to answer it.
I personally think any safety that you gain from using a LiFe is negated by the way your wanting to implement it.
Look it's easy. You've got tonight and tomorrow to get done any stuff you might need to get done before leaving home for a couple of days - work, family, whatever stuff like that. Plan to be on a plane leaving Portugal early Wednesday morning. Fly in to Gatwick such that you're getting out of the airport for around noon. I'll come meet you, and we'll be back at my place by 1pm. I'll make lunch (sandwiches OK?) while you solder up my DNA 200. Then we can play around in the evening! Or check out the DNA 200, whichever you prefer.
Or come tomorrow morning if you can also bring a 11.v battery and/or a suitable 12V charger. Or just if you want to gaze at the "DNA 200 retail packaging" for 24 hours. As of tomorrow I'll have the board but not any of the other bits
I see it in some US locations and saw a post of it on a UK website. As to "should", yea. I got one and will get more when the first round of tweaks is done. The one I got will be a good testbed for some 3d printing and some custom enclosures. My order is in, but I don't mind waiting for them to put what they consider final in the way of firmware on the unit.
Uhmm... this is a DNA200 forum thread. And to be clear, I don't want to implement it, I'm a LiPo fan. But this is in response to folks that don't like LiPos for some reason and were looking into LiFe technology as an alternative and have been discussing it in this thread. Although I do find it interesting that Evolv has provided the programming support to use an alternative battery tech like LiFeP04. Evolv has certainly offered a mind boggling assortment of choices with this board, including a variety of power sources to choose from.
But yeah, I think LiPos are going to be the preferred battery tech for the DNA200 and I think the advantages far outweigh the safety concerns some have about LiPos. But that's just my opinion.
Wasnt intended to be directed to you, Just that conversation.
Here is the official DNA200 forum. It would be best inquiring on there about running a non 3 cell with the board.

I'm with you, buddy. I have a SX Mini M-Class and a Hana V4D. I like them both, but 9 times out of 10 I reach for my DNA40 V4D. I use them both pretty much exclusively in TC, for what it's worth. If I could only keep one mod, the Hana DNA40 would be it.
Well, it's here. Quite possibly the most anti-climatic exciting package I have ever received
No battery and wires until tomorrow so in the meantime I guess I'll.. put the lid back on.

The screen is separate? And on the left below the board, the white thingy, is that a battery connector or what?Well, it's here. Quite possibly the most anti-climatic exciting package I have ever received

Yup what he said! There's a Zero Insertion Force connector on the board to attach the screen. The Balance connector solders to one end of the board, the underside that you can't see in this pic.
But I have just ordered a 12V / 25A power supply and am considering using that for my initial installation, which I had always planned to be desk-only to start with. I figure if I can avoid needing to charge, or even connect the balance charger, that's one less thing to worry about. But I'm awaiting confirmation that can will work like that - there's some suggestion it might expect the balance charger in all scenarios.

Nice idea, thebloke. Put that sucker to good use. I'm sure we all look forward to progress and functions of it. Really think it's going to go off without a hitch though..
Just got confirmation from the DNA 200 forum that I can use a 12V DC charger without even worrying about the balance plug. So that's one less thing to solder!
If anyone else is interested in going the power supply route, this is the power supply I got : 12V DC 25A:

The following picture is indicative, looking similar to the one I got but not exactly the same. This one has three connectors each for V+ and V- where I believe mine has one of each:

Not a very pocket friend solution
This would be perfect for testing the board prior to committing to installing it.
