Thinkvape finder 167 soft cell cut off

[Alastair Paterson]

I got myself a Thinkvape Finder 167 using the DNA 250 chipset and am looking to find out the recomended softcell cutoff for my batteries.
I use Sony vtc5A batteries in the Mod and have 2 sets so i can have 1 set charging whist using the other set.

Initially i set it to 3.2V and noticed that before the batteires would show as drained via the screen the power and vape seemed to drop away.
i have since set it to 2.9V but i am wary of over draining the batteries to the possible detriment to both the batteries and the Mod
i have set the MAH to 18.5 based on thier 2500mah and a combined voltage of 7.4v

@Tubbyengineer is the DNA guru..... he will be along in a while

That sounds good to me, as i dont relish having to shell out another £100+ for a replacment DNA device.
Out of all the mods i have that can do TC it has been the most accurate

The 18.5wh setting is correct, and the 2.9v cutoff will be fine - IIRC the cutoff is the lowest voltage acheived under load so the mod will begin to throttle back the power as you start to hit the cutoff point when firing, most likely the mismatch between firing and battery display is being caused by the discharge curve for your cells, you can run the battery analyser to get the correct disharge curve - Basically all you really need to run it is a couple of loops of decent Kanthal or SS316 mounted in an RDA without the cap, a fan and something tho stand the device on while it runs the test - pick a decent resistance 0.2 or 0.3 ohms should be good, a wattage to fire at (Lower takes longer but is safer if you're using wire as opposed to power resistors), Hook the mod up to escribe and set the analyser running, it will fire the mod 5s on and 5s off until the battery is drained - and then it will ask if you want to store the settings. this will give you a perfectly accurate battery monitor calibrated to your mod and cells...

I take it i could also get a hold of a couple of 0.5 ohm resistors, load them into an rda and set it to fire at 60-70w whilst running the battery analyser
