DNA 200 Watt

[retird]

Here is another image of it powered up via USB:

The screen continually flashes when powered on this way. Is that normal?

You probably need the balancing connector and battery installed. Also might mention to those getting new boards to check that it has the latest firmware installed.

EDIT: According to John at Evolv this is normal behavior without a battery attached: Screen flashing when connected to USB (no battery or PSU connected) - DNA 200 Early Adopters Forum

Yes. you need to update the firmware it was a glitch

Thanks guys...I hadn't read all the way down in that thread to see they corrected it in firmware.

But wouldn't the life span and safety be increased using it that way? Hey I don't know hence why I'm asking.

No. Safety yes but lifespan hardly anything significant. It's the workload that will dictate a lipo's lifespan

I'm not debating lipos. I just wanted to know if one can adjust max cut-off voltage. I was told one can within certain limits. I asked my question to be forwarded to the manufacturer in hopes something can be made to accommodate Hv lipos. that's it. Let's not start twisting things around and try push a given voltage as ideal. I know where this will end. Let's just keep objective.

For your information, that particular lipo can output 56A which means it will already have an expected good life span because it will never have to "give all its got".

Its marginal, on the edge, setups that will kill batteries faster. It's like running an engine on the red line constantly. If a board can pull 25A, don't use a 25A lipo if you want to last it long. The higher the lipo rating, the less work it has to put up with.

That's their right. I disagree with them too if what you say is true (no, not going to waste my time going there)

What do you want? Convince me 4.2V is the best for the hyperion hv?

This is simple. Either the dna 200 will support hv lipos or I will charge them outside the mod. Period.

No point in loosing your precious time convincing me of the greatness of undercharging a lipo designed for hv.

You do know that we used to "overcharge" our lipos 8 years ago up to 4.34V to get the Max out of them? Sure they only lasted 20 cycles but winning was everything.

These hv however are not being overcharged. It's their specs and they have dedicated chargers for them.

There are other people asking the same as I and Evolv will probably accommodate that request unless there is some sort of hardware limitation so I really don't understand your point trying to push 4.2V as ideal?

Why are we arguing anyway? Simple question, simple answer. The end.

So I found a DNA 200 sled on thingiverse.

Wow...you thinned it out a great deal. Depending on when you downloaded it, you should not have had to alter the USB port...a slightly enlarged one was posted on Friday, but that one has the lower window position to make managing the ribbon bend easier. Since you are going to shorting the mount towers, I assume you will use your own buttons or just shorten the chip side portion?

It appears that they can set cutoff charge points as they easily added the drop down menu item for 4.1v. I suspect it can be done. I ordered a Hyperion pack....but I don't mind if I have to wait for the full charge...I am searching for SMALL...which is normally your game. Do you have any good recommendations for a pack? The H HV 900 is thus far the best I have found.
Still the best on the list:

Hv 900 or flightpower 800mah. Both are very good packs and small. The flightpower is smaller though.

The major problem I see is the 510 connector. You need space for it so either you widen up the mod and make the connector fit in between the board and the lipo or you stretch it upwards.

My ideal box would be the beta box widened by 6-7mm and then you could drop the top like at least 10mm and make the connector bottom fit between the board and lipo.

It is physically possible to build a 79mm high box using a 75mm long lipo.

You could even make a 75mm high box but you need to find a lipo under 71mm tall and still accommodate that 510 connector

You would need at least 3mm on the top and bottom for the shell/case. You are right that the 510 has to move...the only way to lower it is to grow a bulge or similar to move the 510 forward. This is the H 900 with VT 51 and DNA200, with the 510 at the edge of a 3mm case wall:

What about having a "tier" on the top, to raise the 510 without changing the over all dimensions of the box?

I left that Flightpower 800mAh 30C off of my DNA200 LiPo Battery Options list when I created it because it's 24A...not quite the recommended amps. But...I don't think people will run into problems with it if they do run it; my preference is for the Hyperion because of its 60C rating.

While we're on the topic of the battery (Hopefully not derailing too much), for anyone with an Opus or using a similar charger and battery for that matter, how long does the battery take to charge?

Also, while I always try to not charge things over night, I sometimes have no choice due to my work / related research schedule. Despite this, I sleep a bit better knowing my chargers will stop their input at 4.2 volts. Does the DNA board have a similar safety feature? Or will I have to continuously monitor the device every time I charge it? I don't want to start another LiPo safety war like the one that existed early in this thread, just a yes/no would be greatly appreciated

I've charged mine from a computer usb, a 1 amp charger, and a 2 amp charger. The usb clocked in at .5 amp while both the other chargers were at 1 amp and all of them stopped charging when full. I didn't time any of them and left them charging overnight each time. The closest time approximation is the last time I charged it, I'd say it was around 20-25% battery left, put it on the 1 amp charger around 3 am and when I got up at 8 am, it was full.

can you link me the slightly enlarged one? The one I have has a slightly too small USB hole.

But yeah this thing will be soley used to mount the chip so it is easier to set in the mod.

But yeah I will be using my own buttons. fire button I picked is abit too big so I can't shorten the encasing as much as I like but I love me some big fire buttons

Good idea. Though would still contribute to the height, it is a good option.

It was the V7 of the sled...but you may have printed that one. I can't tell from your image which file you grabbed. Let me know your version and I can bump it up if needed, but V7 should be very close (may need a bit of file work yet).

Yeah that is the one I printed. The usb is like a touch too small in width and height. We are talking about a mm or two. The screen seems to be good though from fitting.

thank you for that file tho

I can bump it up and update or you can file...it is about spot on for laser printing but bigger would not hurt.

Just want to say thanks for this link, very informative pertaining to my use. I only maybe drop mine down to 75% remaining before charging so that's good but I leave them in the charger and charger on after charged and that's not so good.
I shall be changing my ways.
