TFR/ TCR Curves.

A TCR Curve (Temperature Co-efficient of Resistance) is a plotted chart depicting mathematical rises in a material’s resistance coefficient of the material’s temperature. For example, a Ni200 coil when heated will rise in resistance quite markedly. This rise can be predicted at a given temperature using whizzy maths, and a temperature controlled capable board will be able to use this information to maintain a temperature at the coil and prevent dry hits. It is the basis of all temperature control vaping. Props to Evolv for coming up with that sorcery.

A TFR (Temperature Factor of Resistance) is similar to TCR, but is based on actual observed measurements rather than pure mathematics. We built a complicated and probably quite dangerous rig and measured the TFR of our wire, giving us accurate real-life TFR data. Lars from Steam Engine (a genius and a gentleman) then used this data and translated it into downloadable CSV format to be used with DNA devices. We want people to have the best possible experience when using our wire. By doing this we’re giving you the tools to achieve the best results.

All our TFR/ TCR files can be found int the “Wire TFR Files” section of the downloads page here.

Battery Discharge Curves.

Escribe has a function called “Battery Analyser” which allows you to run a cell discharge cycle according to cell cut-offs and various output wattages (the most common being 40 watts). The analyser carefully plots the voltage decrease as the cell is drained and generates data that can be outputted in .csv format. These curves can then be uploaded to your device to ensure the board is monitoring and reading the current state of your cell correctly whilst you are using it. Whilst this won’t magically add another 10,000 mAh to your battery, it will calibrate the monitoring and information display accurately according to the cells you are using. This way both you and the mod will know exactly the state of your cell and avoid any erroneous readings. 40% remaining  will be 40% usable charge and you won’t get diddled thinking it’s higher. 

We have a wide selection of curves available for many popularly used cells. We have csv data for single cells, 2S and 3S configurations. We shall add many more as they become available. Special thanks goes to Michael Schmidt for providing us with much data taken from his site dna200.de. We also offer up many curves generated by us using a resistor bank made up of two 200w 0.1ohm power resistors in series ,mounted onto an aluminium heatsink to disburse heat  We are running more tests and will be updating the site with curves regularly.

So where can we get these sexy curves?

Easy!
