Efusion dna200 battery problem

[Cooltinha]

I just revived my Efusion 200 yesterday, I think I need to send it back to exchange another if possible, B/c but there's something wrong with the mod, it's work fine right outta box, vape, charge, setting...etc. BUT 10 mins after I change the cell capacity to 1300mah the charging amp drop to 0.10~0.15A on wall adapter and it barely charge on PC 0.05A~0.10A....Then the charging Amp return to normal after going bak and forth like that for almost an hour. After that I charged the mod to 100% and turn on the battery % on main page....But when I vaping...Man the % drops like someone use a knife stab a hole in that Lipo battery, it basically drop ONE % for Each hit, 2~3hits the most, it dropped from 100%~90% less than a minute!! Everytime I look at the screen the % drop after take one or couple of hits....A BRAND NEW mod wasn't supposed to be like this man, it's just really frustrating looking at the % of BRAND NEW DNA200 work like a Lipo that needs to be recycle. Btw I was vaping around 60watts(not too high I think)

post a screen shot of exactly what you have your battery settings at in escribe. also what are the individual cell voltages in device monitor, screen shot as well.

make sure in escribe it's set on '3 cell' 'lithium polymer' '14.43 watt hours' also remember to 'upload settings' to your efusion before leaving escribe.

one more thing, make sure your wall adapter is capable of delivering 1 amp, as well as the usb cable.

Just to add what ChunkyButt200 has said... I wouldn't be to quick to judge a new battery that hasn't been used yet. Sometimes they just need a bit of exercise before they come up to speed. After a few charge and discharges, then see how it is doing.

I'm having similar problems but my DNA200 is 8 months old, ran new(ish) firmware and battery won't charge beyond 42% despite being set to 1300mAh, 14.43Wh as is stamped on the battery. Any suggestions please guys

What does device monitor say the battery voltages are?

what brand is it?  is that battery 8 months old? what are each of the cell voltages in device monitor? they could also be overstating the battery's capacity. if that's the case it will throw the battery meter off. best bet is to run battery analyzer and get your battery's specific curve and watt hour capacity. there is a thread here on how to properly run battery analyzer.

the battery is a fullymax, cell 1 4.18v, cell 2 4.18v and cell 3 3.78 and the mod is an efusion dna 200

cell 3 is out-o-balance. you can try to just charge that cell ONLY through the balance tap with a 3.7 volt lithium charger. bring that one cell up to around 4.18 and see how the pack behaves when re installed in your efusion.

Thanks chunky, where about do I get one of these chargers?

[Daft Chunt]

Apologies for sounding a bit thick, but I'm pretty new to this mod and cloud chasing business :-)

you don't have an 18650 battery charger laying around? hang on, a friend of mine here has a pic showing what i'm trying to explain. let me find it.......hang on

[dwcraig1]

The pack is somewhat unbalanced, it's a very slow process using the on-board charger to get it balanced. It may eventually balance or perhaps cell 3 won't charge any higher due to a bad cell. If you have a meter check the voltages on the balance connector or the power wires, your voltages add up to 12.1 volts and see if they match up to what EScribe says.
BYW 12.1 is 95 +% roughly of 12.6 volts

[Spector NS5 RD]

if you want to try this. dwcraig1 can explain more. basically you're targeting the unbalanced cell. you want to bring the voltage up on it. you single out the unbalanced cell through the balance tap for charging.

[Daft Chunt]

The stamp on the battery reads as Fullymax 1300mAh 14.4Wh 11.1v 5385*1727

[Daft Chunt]

I have a night core charger somewhere but I don't understand how I can isolate the individual cell to bring it into line with the others

[Daft Chunt]

Is that safe?, Looks kinda Frankenstein dangerous to me

[dwcraig1]

It's safe (enough)
Your only looking at 4.2 volts @ .7 amp
Well the wiring must not short as it has quite a bit more power, connect the wires to the balance connector last and disconnect them first.

[dwcraig1]

In the picture a couple posts back it is cell #3 that I'm charging, that's using two pins on the positive side of the connector. The outboard (#3) is positive and next one (#2) is negative.
Mine got out of balance because I got e liquid between the connector and board. I thought it was the battery so I replaced it, soon it had the same problem. Then I cleaned the area and problem never came back.  

[dwcraig1]

I type slow

[Daft Chunt]

What wire did you use?, Just want to make sure I'm doing this right n not trying to blow my self up, lol

Something around 24 gauge solid copper bell wire attached to the right length juice bottle.

So this is how I go about it, again I apologise for my general lack of knowledge but thanks for your time guys - much appreciated

Sorry , do you mean you want me to tell you again perhaps a bit more detailed?

[Daft Chunt]

I'm trying to load a picture but not going very well

[Daft Chunt]

Hopefully.......
