2s 18650 discussion

[John]

It is a drop down, click on it and change it to 2s. On the mod tab.

Upload this curve into the battery discharge curve. Note that the curve is for lg he2 cells. http://evolvapor.forumchitchat.com/file?id=2391339

is this discharge curve for the battery meter? Or does the chip use this curve for other things, plus is it a standard curve for that type of battery or is it a combo of batt and chip profile?Im going to be running sony vtc4 batteries

[John]

Just for the meter. It doesn't have to be exact as long as it is generally correct. 

[adski]

I must be blind can you point it out?  

[John]

Oh wow, that is a strange display bug. The thing that says 3 cell should be a drop down. I bet it works if you click on it. 

Is this windows 8 or 10?

[adski]

Windows 10. It does nothing when i click on it.

[adski]

I reinstalled escribe yesterday when i updated to windows 10 and have since updated escribe.

[Guest]

Would this work for people that want to type there batt curve in manually?

[Guest]

Or this

[retird]

EScribe version 1.0.28, Firmware version 7/29/2015, and Windows 10 64-bit Home version here and the drop down for 3 cell/2 cell works here.

 

[VapingBad]

Is it as simple as an older version of escribe?  IIRC 2015-07-2 or later is required from here

[adski]

VapingBad you are the man!
I must have downloaded an earlier version. Weird because escribe offered me an update.

Can someone make a wiring digram for how to connect the battery sled to a DNA 200 for a dual 18650 mod.
Please and thanks
I'm considering a dual 18650 version of a DNA 200 mod.  Just want to get it straight in my head how it's wired

Laguz, yes, if you don't want to use Battery Analyzer you can put in a curve manually. The only difference is that EScribe wants the curve in percent remaining, not mAh. (It splits out Watt-hours as a separate setting.) I think you will find Battery Analyzer produces a similar result, though.

ill run the battery analyzer first and see how it comes out, what about the wire profile curve, what would the results be if I set more points along the curve

A simple diagram will help all of us with dual 18650 configuration. John already mentioned that we need to bridge tap connections 2 and 3, but how exactly the 3 wires from the tap are connected to the battery sled?

[valld]

 

This should help I guess. From bottom to top on the diagram: the '+' wire will go from the battery holder '+' to pin no 2/3 on the board, the middle wire will go from the battery holder bridge to pin 1 on the board, and the last cable will connect the battery holder '-' to ground tap connection on the board. Please correct me if I'm wrong.

I'm trying to get this up and going and can't get past a "Check Battery" message when firing. I am getting 8.4v and in Device Monitor I am reading 4.2 for cell1 and cell2. Cell3 is reading .6. Any help would be appreciated.

Some additional info. The board works fine set to 3 cell with a lipo. I set it to 2 cell, load the curve, and set wh. It will then show the error after I connect the 2 cell sled. I metered the sled and get 8.4v, cell1 4.2v, cell2 4.2v, cell3 0.0v. It also seems to be charging properly. Cell3 shows voltage jumping around .5v in Device Monitor.

I have taken wattage to whole way down to 1 with a preheat of 10 and still seeing this. Also ran over all of the solder joints to make sure they are good.

I am also running the 8/5 version.

Thanks,

Rick

Here is the sled

[Dejay]

To my unsohpisticated eye it looks like the both white wires should come from the bottom (white to 2+3 pin)

Like you wired you would always have 0 voltage for one cell and the DNA200 probably thinks one cell is busted.

Why so many leads for the balance charger?  With a 2s configuration you have a common ground, an intermediary hot and a final hot.  What are you trying to accomplish with the others?  

[valld]

Did you set your battery configuration to 2 cell? You are not supposed to see a third cell 'cos it's not there.

I was using the #s connector and wiring 2 and 3 together.  What's confusing me is that Device Monitor is showing good voltage on 1 and 2. Not sure what it is supposed to look like in Device Monitor on a 2 cell config.

It is set to 2 cell in escribe.
