boxer 167 battery flash after 60% & lower

[EDMKEV]

Hey guys so i recently bought a mod used with a broken screen, luckily gingervapes had a 6 month month policy so i sent it in & it got fixed and sent back. I didnt use it for a few days then i put my rdta on it with fresh charged 25r's.

0.14 ohm set at 90watts

Working fine up untill I now noticed once i got to 60% battery, the battery symbol would flash and i was getting throttled power  (50-60 watts)

Tried a new set of batteries, works fine but again once i get to 60% throttled power.

Went into escribe and the cell 1 & 2 were even 4.2 (tried with fresh batts) any idea whats going on? Sad i just got it back from repairs & its not working again now.

Flashing battery symbol is a weak battery error message..... your setup of 90 watts @ 0.14 ohms requires 25.35463 amps.... May be battery sag due to large amp draw with your setup..... ohm's law is your friend.....  I don't think there is anything wrong with your device.... try building  a different coil which draws less amperage....

Ive had tons of mods vape past 60% with lower builds dna's & chinese chips..my therion is past 50% with a 0.1 @ 115 watts drawing 33amps off 25rs not flashing battery symbol or throttling power...so thats how/why it seems not normal...maybe just to make sure it clear its dual 18650 boxer dna250/167 & same with my therion.

I would guess its a problem with the contacts on the battery sled if it is of the flat bent sheet metal type.

[retird]

In Device Monitor are you seeing excessive battery sag with full batteries and excessive sag at 60% charge?  Do you still get the flashing battery with a build requiring less amperage?

[EDMKEV]

Oh ya i noticed this yesterday but i forgot to mention the contacts are still bent fine but on botton right side, that contact..the gold plating has cracked and theres a small chunk of gold plating missing...the bend seems to be ok looks even with the other one and they both hold the battery in place pretty solid but would that be my issue? I figured it should still have pretty good conductivity as long as the bends are ok

I dont even know how that happened

Ill have to double check that and let you know later today

[EDMKEV]

And yes they are that thin sheet metal type of contact you can bend

Not much doubt then that that is the problem. Search the forum for more on that using the "search" feature.

For example:

So an update, read through your topic and did some sesrching but couldnt find much to help but i was thinking that the gold plating shouldn't effect the conductivity by a night and day difference in terms of conductivity. I wont be able to get it on the device monitor for a few hours but i tried bending the contact a bit more just in case, so far it seems to have worked, ive gotten down to 54% so far so to the eye the contacts looked fine but i guess maybe it was flattened enough to not make a good enough connection...ill keep using it and update you with whether bending it fixed it for good..i did kinda ruin more of gold plating though so i hope that doesnt become an issue as well..

[EDMKEV]

**another update

after hitting it a few times more i couldnt get below 54% before i would get check battery

here's a little bit more info about troubleshooting i did.

when i left the device in boxers default settings, the device would *sometimes* flash the battery bar but not always but it would always throttle my power from 90 to 60 or so

i tried changing the soft cell cutoff to 2.7 i read somewhere in the forums, and instead of throttling power or flashing the battery symbol, it would just cut power & display "check battery"

 

i just set it back to Boxers default settings for now and took this snip, hopefully you guys can make more sense of what the device is doing. I seen there was another topic with a guy with a therion having check battery issues, havn't gotten a chance to read it yet but i will soon here.

[retird]

From your snip we see a pack voltage of 7.44 (3.72 v. each cell) when not firing.  What does the pack and cell voltages drop down to while firing?  When firing your snip shows the 90 watt setting only reaches 65.23 watts.  Could it be that battery sag is what you are seeing since it doesn't do this when batteries are at full charge?

Ill have to re create this and take 2 snips because there is no scale on the sides showing what level it is sagging to. So ill have to point to it with my mouse to show the level at rest & under fire.

But i only get this problem with this device, i could pop those batteries out and put it in my therion with the same atty and continue to vape without any sag or throttling of power.

Also have tried with 4 different sets of 25r's so i dont think the batteries are the issue..3 sets of batteries are brand new as well.

either your cells are garbage or you have poor connection somewhere between the cells and the board. since those cells work fine in your Therion, that leaves only the battery contacts. Those contacts Boxer uses are less than stellar.

here's an updated snippet and 1 showing the same batteries on my therion with same atty & wattage

ya i think your right, waiting to hear back from boxer...again.

my mod just came back from them too & was still under warranty at that time, now its not so im not quite sure whats going to happen now.

guess i'll see if they cover it, i dont mind paying but still want to see if they'll cover it since it went out of warranty while it was in their hands. 

[Spector NS5 RD]

If they simply replace the existing ones with the same style, my guess is you'll have the same results, maybe not immediately but down the road, taking cells in and out from the mod. More robust contacts are what's needed. Who  knows, maybe they have a fix / workaround I'm not aware of.

Well i did buy the mod used so it wasnt in my possession since the beggining and i believe the previous owner didnt take care of his mods to the extent that i do, but yes i agree..even if i do take care of it once replaced, its likely to have the same issue if replaced with the same contacts..kind of a shame since boxer mods are pretty good quaility but they're only as good as their weakest link

Well guess ill wait to hear back from boxer..at least mines explainable guess alot of the therion problens are still not.

[EDMKEV]

So sorry this is gunna be a long post..i have been talking to GingerVape and hoping you guys can give me some insight on how i should go about a answering them & if my logic is sound as well.

Here is a snippet of part of the conversation after I provided them with the graphs ive posted above and explained the flaking of the gold plating which they said it should still work regardless.

Their response..

Again, the Boxer is set with a battery discharge curve and Wh for our US18650 30A batteries.  Obviously your theriorn is not and this will have an effect when not using the batteries.

As mentioned if you run the battery analyzer at the wattage you vape you will get a true rating for your batteries and usage and it will run down to close to zero percent afterwards.

Yes…. if you have a voltage loss somewhere, this will cause an extra sag and a reduction in Wh.

So i replied with..

Ok so essentially, can't i just take the setting from the therion and save them and upload them to my the boxer and it should work the same as the therion and not be set to the 30a battery anymore? Or

I am willing to go buy a brand new set of VTC5A 30A if your saying thats guarenteed to work and i wont have problems with throttling anymore because when i tried my friends i had the same problem with throttling power but maybe he had bad batteries?

 

 

 

 

Got a.. in my view pretty dismissive/rude responce back but anyways, I am still getting throttling after buying a set of brand new Sonys VTC5A. Instead of 55% percent I get to 45% percent before again, it flashes the battery & throttles the power down. So my understanding is if im STILL getting throttling with a brand new 30amp battery there is obviously some connection problem somewhere & running a battery analyzer wont really fix this problem or do me much good because sure i wont get a flashing battery or throttle power anymore but my vape time is going to get cut at 45% with sony vtc5 30amp batteries or 50% battery with samsung 25rs, just like it is now but it will just show me a 0% battery quicker because the battery analyzer was done with this connection problem. Plus i dont think i should have to run battery anazlyer just to get my battery percentage down past 45%. im not sure if this will address the real problem and just give me a work around to make it seem like its working normally. Ive never had to do this with my other 167 chips & im not sure if im correct but if theyre not willing to explain it to me, was hoping the community might be able to help explain it to me better or if im not grasping something here.

@EDMKEV Try to attach some foam rubber to the bat contacts - right there where the metal is bended ----- it´s not recommended to bend the contacts more open - putting foam rubber into the bending point gives much more mechanical force 

[EDMKEV]

Ya i guess ill try that, id have to find some pretty firm rubber foam though, not quite sure where or from what i could find that from and it would have to be a pretty small piece since there isnt much room like your pictures shows, it looks kinda like it does in the picture but i think it'll be a bit tough.

Couldn't i use a thin piece of business card folded a few times and shoved underneath to try to make a more solid connection?

[Lowbytes]

@EDMKEV I´m pretty sure that every material that gives enough force will work - i´d recommended foam rubber because it works like a spring - i´m sure you´ll find something similar - for security reasons non conductive ;-) 

 

[dwcraig1]

A rounded surface against a flat surface has very little actual contact area, flat to flat has much more.

But not that easy to modify...........i wish they´d used better bat contacts ....... did not find any replacements for the contacts.....

 

[dwcraig1]

That style of contacts is fine for toys and low amp draw flashlights and such but not a high amp device like a DNA200
