The mounting points (board to case) does provide heat transfer. Of coarse with a plastic case that's not happening. The board once the sled is removed the board should be held in place by one screw that sort of hides under the 510's ground wire. On some DNA75 mods the mounting screws can provide ground for one or both the battery connection and 510 so only two or three wires are used to build it. Oh, BTW..great news

Might want to see if it will fire from the "Puff "tab in Device Monitor, maybe the fire button isn't working at all. Just thinking.

Is the screen black before you press the fire button as well?

The 200 boards (with the exception of the latest ones) only charge at a maximum of 0.5 amps when a data path is present. If you have a 200 then that's to be expected.

In EScibe under "Help/ About EScribe" you will find your version of EScribe. In EScribe Device Monitor in the lower right hand corner the firmware on the device is listed. The latest is always found here in post #1: /topic/66731-topic/?do=findComment&comment=900119

Just an example: http://www.ebay.co.uk/itm/Voltz-1300mAh-3S-11-1v-30C-LiPo-Battery-/172113838208 or https://hobbyking.com/en_us/turnigy-nano-tech-1300mah-3s-25-50c-lipo-pack.html

Did the unloaded pack voltage drop also or just the percentage?

Same thing happened to my VT133, Evolv had me send in the board and they sent me a new one. They were going to let me send the whole mod but I just sent the board.

Sorry to tell you but the board is the problem.

My money would be on the battery contacts...just saying.

0.3 ohms (hot if TC wire) @ 6 volts =120 watts 0.2 ohms at 6 volts would be 180 watts Here I'm seeing around 3.65 volts /topic/65896-topic/?do=findComment&comment=892026

What does eScribe show for cells 1 & 2 voltage?

No additional files are needed for Nichrome or Kanthal, the board automatically stays in power mode when using them.

You want the 167 version, right? PM sent.

Set at 133 watts, got 133 watts....for sure pushing it

I'm guessing here but all the +'s are really the same no matter their label. So if you pick up power off just one it could power the added board for all buttons. How about a picture from the side showing how the 6 connections are made from one board to the other?

I guess I might as well through this in. The DNA200 has a hard cell cut off of 2.85 volts unless that changed with firmware update, I don't know but doubt it. Probably the 250 is the same in regards to cut off, again I don't know for sure. The 200/250 was designed to operate with a LiPo pack not round cells (18650, ect.) hence the higher soft/hard cutoff. 18650's, ect have their mah capacity measured between 2.5 - 4.2 volts, a lipo shouldn't be drained down that low. So when you use 18650's, ect. with a board designed for a LiPo pack so the capacity of the round cell between 2.5 and 2.85 volts is not usable. I set my round cell powered 200's 12% lower than what the calculator comes up with. A firmware update listing the round cells would be an option but for sure folks would be using it with a Lipo and that could end up being a safety issue. Call every thing here "just my opinion"

It isn't showing the value of the loaded pack (sag), what is the voltage? Might have two problems going on there, providing that's a TC profile.

It appears Google Translate isn't cutting it. Must be: What does "check battery" mean.

I suspect your problem to be with the battery sled contacts, you will soon see. HE2, HE4, 25r's....all good
