haveacigar Posted October 20, 2015 Author Report Share Posted October 20, 2015 Does this every charge cycle. Drops about 20% quickly and sometimes even reads weak battery at 30% after about 30 puffs. Vaping .5 ohms at 55 watts. Link to comment Share on other sites More sharing options...
valld Posted October 20, 2015 Report Share Posted October 20, 2015 Did you set properly your battery in EScribe? What EScribe device monitor is showing in battery related fields? Screenshots from both screens would help resolving your problem. Link to comment Share on other sites More sharing options...
haveacigar Posted October 20, 2015 Author Report Share Posted October 20, 2015 Yep. Updated through escribe and put in what seems to be the general consensus is the proper "battery capacity" to input at 14.43. Link to comment Share on other sites More sharing options...
blueridgedog Posted October 20, 2015 Report Share Posted October 20, 2015 If you get such performance at 14.43, you have probably overstated what the wh capacity is vs reality. You can try something like 11 or actually measure it with battery analyzer. Link to comment Share on other sites More sharing options...
haveacigar Posted October 20, 2015 Author Report Share Posted October 20, 2015 UPDATE: Box does not charge any more...well...it does, but at .09Amps as opposed to the .97A that it used to charge at. Link to comment Share on other sites More sharing options...

blueridgedog Posted October 20, 2015 Report Share Posted October 20, 2015 Suspect a bad pack then. Can you post a screen shot of device monitor so we can see your pack/cell voltages as well as USB input voltage? Link to comment Share on other sites More sharing options...

blueridgedog Posted October 21, 2015 Report Share Posted October 21, 2015 In Escribe, click "Device Monitor" and you can see the charge levels of each cell as well as lots of other data.It is a great tool and you can vape while watching to see if your pack sags badly.I have seen a good number of folks with that mod complaining about limited capacity and sag. Some have complained to the manufacture and gotten replacement packs. Link to comment Share on other sites More sharing options...

James Posted October 21, 2015 Report Share Posted October 21, 2015 That battery is nearly dead and needs to be charged.If your battery capacity was set wrong, the percentage you are seeing in the meter may be off. Get the capacity set right, let it charge up to around 4.2V on all cells, and let the USB Current taper off. You should be in good shape.It will charge at 0.1A if the battery cells are below 3V for safety reasons, as well as if the room temperature is too cold or too hot.(Once the cells get above 3V it will go back to a normal charge rate.)

haveacigar Posted October 21, 2015 Author Report Share Posted October 21, 2015 Ya, but it dropped from 45% to that 0% and wasn't charging at the same rate yesterday, until I plugged it in this morning. Any idea why that is? Link to comment Share on other sites More sharing options...
James Posted October 21, 2015 Report Share Posted October 21, 2015 If the meter is jumping that means it is automatically correcting for a significant mismatch between the battery capacity and/or discharge profile curve vs. what it is reading from the cells. If it thought it had 45% at 3V/cell, the meter is definitely in the wrong spot.This can happen after the battery capacity and/or discharge profile curve have been changed, but if they are set right, it helps to let it charge up to full once so that it has a good starting point for its metering, as the corrector is just an estimate.The board temperature is fine so it doesn't look like anything is off there.

haveacigar Posted October 21, 2015 Author Report Share Posted October 21, 2015 I've been letting it charge all the way up and then vaping until the "battery is weak" which usually happens at around 40 puffs. You're thinking this is the battery, or the change i made to the "Battery Capacity"? Link to comment Share on other sites More sharing options...
blueridgedog Posted October 21, 2015 Report Share Posted October 21, 2015 What is the capacity set at now and can you take a shot of you vaping normally to show the voltage sag? Put a check mark in each cell box to track them. Link to comment Share on other sites More sharing options...
haveacigar Posted October 21, 2015 Author Report Share Posted October 21, 2015 Capacity set to 16. Link to comment Share on other sites More sharing options...

blueridgedog Posted October 21, 2015 Report Share Posted October 21, 2015 My opinion of looking at your graph is that you have some moderate voltage sag while vaping. Also your capacity setting is a bit high for the real life of that pack. I would:Let it charge fullyChange capacity to 13 (just as a test)Vape again with the device monitor on and just look at the cell voltages to see how low they go.The area to look at is the cell voltages that you can see dip while you vape.Thus far it looks like a basic poor quality Lipo pack. Just for comparison, here is my pack taking a similar hit (the sag is there, but not forming a big dip): Link to comment Share on other sites More sharing options...
haveacigar Posted October 21, 2015 Author Report Share Posted October 21, 2015 Gonna take a bit to charge fully. Any suggestions on replacement LiPos? Link to comment Share on other sites More sharing options...
blueridgedog Posted October 21, 2015 Report Share Posted October 21, 2015 I would start with the vendor or manufacture and ask for a replacement. If they give you the bum deal, they you can take the existing pack and measure it and source something on the hobbyking site (they have a great tool and their Trunigy products have proved inexpensive and good performers). I have a few of these and if they fit, are great:http://www.hobbyking.com/hobbyking/store/__11903__Turnigy_nano_tech_1300mah_3S_25_50C_Lipo_Pack.html Link to comment Share on other sites More sharing options...

With the new capacity setting, there doesn't seem to be any major battery level drops any more, though the battery still drains semi-fast. I'm satisfied for now. Thanks again!
