dwcraig1 Posted November 9, 2015 Author Report Share Posted November 9, 2015 Does the battery icon have the charge symbol when it's balancing, does it show any amperage? How long does it take? Should I keep it on charge for a couple of days?It was similar to this so I changed the battery. I tried to balance this battery and the original battery with the cheap charger that comes with the Hotcig mod, all it does is overcharge the "good" cells. It stops charging when 1 and 2 reach 4.20 volts, or I think it does. Link to comment Share on other sites More sharing options...

If you hook it up to escribe you can trace the charge amount of each battery and monitor, you can also change the DNA screen to show charging rate, voltage, pack voltage.I think anyway, someone more clued up will be along soon no doubt to assist further.

Spector NS5 RD Posted November 10, 2015 Report Share Posted November 10, 2015 is there any way you can multimeter each cell and post what they are. maybe escribe is a false number for cell 3edit i doubt two batteries would have the same problem in the same exact cell, which leads me to think a bad solder job on cell tap 3 on the board or the the charging portion of the dna is going kuh-blu-ee Link to comment Share on other sites More sharing options...
OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 Hi all. I hope someone could help me. So i left my mod for its first charge over the night. I came to it in the morning and cells were reading 4.20, 4.12, 4.20. No matter what i do now that middle cell wont go up. It only got to like 4.09V and than back to 4.12V. I tried everything. Please help me! Sorry for my bad english. Thank you all! Link to comment Share on other sites More sharing options...
VapingBad Posted February 4, 2016 Report Share Posted February 4, 2016 The balancing happens at the end of the charge cycle, it works by discharging the highest cell or cells then charging them all again until the highest reach the max voltage and should repeat until they are all close enough. This happens at a very low current so it takes time and it is conceivable that if your USB supply switches off when the current drawn is low that it doesn't get to finish. It is implemented like this as all 3 cells have to be charges together at the same rate. Link to comment Share on other sites More sharing options...
OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 Thank you for ur reply. I didnt get anythig from that... Can u explain to me what should i do please? Thank you very much! Link to comment Share on other sites More sharing options...
VapingBad Posted February 4, 2016 Report Share Posted February 4, 2016 Give it time and maybe try a different USB supply, if you have USB Current as one of the fields on the charge screen you can see when it stops charging it goes to almost 0.000 A.

dwcraig1 Posted February 4, 2016 Author Report Share Posted February 4, 2016 It's a slow process, slower than slow in fact. Link to comment Share on other sites More sharing options...
OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 It curent is now 0.80A Link to comment Share on other sites More sharing options...
VapingBad Posted February 4, 2016 Report Share Posted February 4, 2016 0.080 A is still charging, almost certainly balance charging if it stays around that level for long. After you get it balanced if it continues to go out of balance a lot you either have a faulty battery, wiring or board, in that order of likelihood.

OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 So my Device Monitor looks like this now. Is it okay? Should i leave device connected? Link to comment Share on other sites More sharing options...
VapingBad Posted February 4, 2016 Report Share Posted February 4, 2016 If Cell 2 is not changing from 4.12 after a time (sorry don't know how long, say an hour) then if you are confident to remove the battery and test on a multimeter I would do that. On the white plug with 4 terminals test the voltage between the middle 2, if it is 4.12 V then the battery is faulty, if it is 4.2 V then the wiring/soldering is faulty or dirty.

OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 I dont have that connector there. Its just balance wires as i understand. And it has been 4h no moving. It moved to 4.16 at the start when i tried to fire atty and it sad unbalanced battery. After that it was 4.16 and slowly dropped on 4.12 while on charger. Sorry for my bad Eng...

lewisss Posted February 4, 2016 Report Share Posted February 4, 2016 I would use the mod to let the voltage drop on all the cells. From what I have seen on device monitor it looks to me like the balance process works throughout the charging cycle ie if you have two cells at 3.7 and one at 3.5 the 3.5 one will charge faster until it catches up. This is quicker at lower voltages as the device is demanding the full current charge. To do it when two cells are practically fully charged will take an age!

OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 I cant use it... it say imbalanced battery Link to comment Share on other sites More sharing options...
lewisss Posted February 4, 2016 Report Share Posted February 4, 2016 Sorry. Did not realise that! But I think being 0.08v difference should not being up unbalanced battery message Link to comment Share on other sites More sharing options...

OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 After firing it a few times i jumped at 4.17. It was under constant pop up of the imbalanced battery and reducing my wattage Link to comment Share on other sites More sharing options...
OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 And its slowly droping... Its at 4.15V now Link to comment Share on other sites More sharing options...
dwcraig1 Posted February 4, 2016 Author Report Share Posted February 4, 2016 Here's a screen of mine when the battery was unbalanced more than this one, there was no unbalanced message and the mod worked good.https://forum.evolvapor.com/topic/67594-topic/?do=findComment&comment=908452There must be considerable voltage drop when under load perhaps. Looking like a bad cell or connection between cells under the shrink wrap.I'm just thinking out loud here.(my situation above ended up not being a bad battery BTW ) Link to comment Share on other sites More sharing options...
OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 I dont relly know what to do now... i will leave it connected to the pc ohe night. If that fails than i am hopeless. Link to comment Share on other sites More sharing options...

It would be great if you could post a screen shot like above while firing to be able to see the voltage drop on the individual cells. Link to comment Share on other sites More sharing options...
OSvaper Posted February 4, 2016 Report Share Posted February 4, 2016 Here it is. After that it gets to the 4.15V and slowly drop to 4.12V-4.13V Link to comment Share on other sites More sharing options...
