fich Posted October 30, 2015 Author Report Share Posted October 30, 2015 hi guys, ive got the vt200, been using it a few days, set the wh to 11.1 as suggested. ive noticed something weird, my mod said that battery %was %55, i hooked up to escribe to chnage a few screens, uploaded to device and it shot up to 72%, so uploaded settings again and it shot upto 92%. according to device monitor pack was at 12.48wh?anyone had any experience with this kind of thing? any help would be appreciated, cheers Link to comment Share on other sites More sharing options...
fich Posted October 30, 2015 Author Report Share Posted October 30, 2015 So according to device monitor the pack is now full 12.6v and all cells at 4.2v. Yet the battery indicator says 97%, wh set at 11.1wh. So I've uploaded settings again to see what happens and battery %dropped to 91%? Really strange Link to comment Share on other sites More sharing options...
Popeye Posted October 31, 2015 Report Share Posted October 31, 2015 My vtbox 200 is doing something similar.When i charge it, it eventually displays 100% at 11.9V pack voltage, if i do a soft reset it drops down to 70% then charges normally. After this it charges to 4.2V per cell.Seems to only happen if i drain the battery below 11.1V Link to comment Share on other sites More sharing options...
fich Posted October 31, 2015 Author Report Share Posted October 31, 2015 It's very strange mate, it's sorted itself out now, in device monitor the pack showed fully charged, all cells at 4.2v, wh set to 11.1 but battery percentage was showing 96%. I uploaded settings to device 6 times and the percentage changed to 100% now everything is working as it should. I've noticed though that when charging and the device goes to sleep, that on wake the battery percentage doesn't change to the correct charge percentage until I fire it. Surely this is an issue with the chip? Thx mate Link to comment Share on other sites More sharing options...
fich Posted November 1, 2015 Author Report Share Posted November 1, 2015 OK so I set my vt200 to 11.1wh, I've ran it down to 0% and checked device monitor and my cells are all averaging 3.5 v which indicates I need to set it higher than 11.1wh. So I've changed it to 12.21 as it came when I bought it, uploaded settings but the battery percentage and battery fill meter are not changing? Is this a problem with the chip? I could do with some help if anyone could it would be greatly appreciated, cheers Link to comment Share on other sites More sharing options...
Coldxrain Posted November 1, 2015 Report Share Posted November 1, 2015 So which is it 11.1 , 12.21, or 14.43? Link to comment Share on other sites More sharing options...
fich Posted November 1, 2015 Author Report Share Posted November 1, 2015 I have absolutely no idea, it's all over the place mate. I've set it to 12.21 again as it came from the factory. The battery % changed. I plugged into wall charger, came back to it and it was at 64% charge. Plugged into escribe and it jumped to 72% charge, didn't change any settings as regards to the battery. It's really starting to do my head in lol might run battery analyser tommorow but I haven't got access to a test rig so it will have to be 2 big loops of kanthal. I was hoping someone from evolve could chime in and give me a few pointers. I just want an accurate battery meter lol Link to comment Share on other sites More sharing options...
bmclaurin Posted November 2, 2015 Report Share Posted November 2, 2015 I wish I could help, but other than suggesting that you run the battery analyzer like you've already said you intend to do, I'm not sure what else to add. It's unclear to me how the Wh setting in escribe influences the on-board battery meter (since it only indicates capacity as a percentage, which can be derived directly from the discharge curve .csv using only the battery's resting voltage). But running the battery analyzer for yourself will give you the best measure of your pack's actual capacity. When running it, I suggest running it at a power setting that is representative of your typical vaping style, and set the LVC to a level that is satisfactory to you (evolv's default 3.09v is a good place to start IMO).

fich Posted November 2, 2015 Author Report Share Posted November 2, 2015 It's very frustrating, I've set the screen to show pack voltage for now and I'm just ignoring the battery meter completely. I've already got soft cutoff set to 3.09, I will get analyser done at some point it's just the fact I'm gonna have to sit with it for a couple of hours while it's doing its thing lol Link to comment Share on other sites More sharing options...
fich Posted November 2, 2015 Author Report Share Posted November 2, 2015 Think I've cracked it, I've noticed through device manager that when I fire the mod, there is a little battery sag, when the battery sags a little, the battery meter and percentage drops but the battery recovers straight away, so the meter is not going back up to match the battery. Once hooked upto escribe the battery meter jumps back up to where it should be. So for my particular battery 12.21wh is the actual setting. I'm sure if I run battery analyser it will recognise this sag and give me a perfect battery curve. I've been vaping from a full charge all day at 100w heavily and my packing still reading 11.4v so not even half discharged. That's pretty good battery life for me. I will continue to use the pack voltage display on the vt200 and just ignore the battery meter until I run the analyser sometime this week Link to comment Share on other sites More sharing options...
