You canât say? Why bother posting all those pics if u canât explain what supposedly is wrong?
Can anyone say? Thereâs no fishpaper between groups. Yes. Anything else?
You canât say what these smart people told me im doing wrong?
Hard to disagree with someone when they donât actually make a point.
And first to be insulted because I canât imagine any other reason the bms isnât working. ⌠while not actually posting any reasons. Itâs saying ur smart but being incapable of showing it.
Know it all dick heads over and over.
I mean I donât build batteries, but have built a couple in the past.
I wouldnât use packing tape, you can still get a short thru it. Maybe if there was a case it was in then It wouldnât throw red flags in my head.
You said it yourself no fish paper, There should be fish paper.
Some of the solder joints look to be not attached very well as in they arenât using all of the surface area on the cell.

Like yeah I would agree its a battery and it will work, ive built worse looking batteries, but ive also had a couple catch fire (seems like youre the same there)
If it were me would pull that pack apart and redo it. But we are all different.
My head is screaming no, that is not a good idea,
But yours might not be which is fine everyone has differing opinions
I think what @BenjaminF and @xsynatic are trying to get to is that they wouldnât run that pack and they already advised you what they think on it.
Moving onto the BMS thing, have you checked B- and all the balance leads?
I know that might be stupid but I just had a similar issue and it was bc my -b was connected wrong on the Battery side, not the BMS side.
I know overkill solar has an âadjust BMSâ type of setting where you can go in and manually adjust the cell voltage after checking with a mulitmeter. That happened to me for a little bit before I recognized what was going on.
That being said once again im not a battery builder just a dude who has an eye for things and has a good knowledge of batteries.
LMK if that helps at all lets try to figure this out

Iâve never had a fire. Thatâs a big short from the charge port being wired backwards when I went to charge. I posted it as a warning what can happen. Iâve always used lifepo4 to be safe till just recently.
You can cut through aramid tape pretty easily too though. I didnât sell it with a case. It was sold as is and if had a problem with it they couldâve come to me.
Ive had the same people post this same battery for maybe years now. It needed fishpaper. The soldering looks fine and not being beautiful doesnât make it dangerous. Thereâs nothing more theyâve said about it in the past and theyâre not saying anything at all now. They bring it up out of nowhere whenever.
Actually as I say it wasnât the topic. The topic was a possibly faulty bms. No advice was given by them related to the topic just insults and a battery I made about 2-3 years ago. They wonât even talk about the battery. Iâm not listening they say. I donât see them writing anything to listen to. Iâm supposed to read the whole thread they say.
At this point if I keep getting unrelated insults Iâll be giving them right back.
Iâm glad to hear that this is obvious to other non-hummie readers.
Also, Iâm sorry that you have been sucked into wasting your time trying to explain anything to hummieee. I hope you succeed, but Iâm confident you will not. I encourage you to do something more valuable with your time. I know Iâm coming across like a massive dick here, and thatâs simply because of how long hummie has been doing this exact same song and dance.

I ended my comment with that to try and help you out. Maybe @BenjaminF and @xsynatic made the right decision to stop helping you as you let your emotions get the best of you.
Maybe try looking at it from our side âlet me see if I can help this guyâ
This guy, âno youre wrong and you make me angry bc you donât like my packâ
Us âokay well you donât seem to want help even when askedâ
@BenjaminF I think I have reached the same conclusion. You canât help someone who doesnât wanna be helped.
Hummie good luck but youâre attitude killed my ever growing want to help someone.
If you want help from me ill second @xsynatic deal $100 to my paypal.

Not what happened at all.
I was asking for advice on how to make the bms work. They didnât give any advice as u can see. Just gifs n memes and a battery from years ago.
They say I canât be helped and I wonât listen. When I ask what theyâre talking about⌠nothing. Told to read the whole thread.
@BenjaminF if I run lipos in parallel, will that double the output current? or does it stay the same. As in if its 10C will it be 10C, or 20C?
I want to make sure I donât raise my battery current too much
So u did give advice on the bms and not just post a meme insinuating I was missing something? Itâs pretty clear.
you did not post any advice and instead just posted a meme insinuating I didnât know what I was doing. Am I wrong?
Awesome! Glad to see Iâm not the only one. Seems like a cheap, easy and most importantly cool looking way to get a robust enclosure.

Can you say what Iâm wrong about? What is everyone else right about? But donât just make a broad empty statement. Post exactly what ur talking about
How bout some words instead of gifs n memes
I should post the pages and pages of people here telling me Iâm an idiot n danger since I told people you can charge cells that have gone below 3v. You were one. Such long eloquent writing but the reality remains and the manufacturers say u can.
What else? What am I wrong about? Again, be specific.
This is a boring question, but which has been made interesting by the way you phrased it 
Ill explain:
The reason is that âC ratingâ is not a simple spec. It doesnât tell you anything about a batteryâs current rating on its own. Itâs a relative spec, dependant on a batteryâs capacity. To find a batteryâs current rating, you multiply the C rating by the capacity in amp hours.
Putting two lipos in parallel will double the output current potential. However, it does NOT double the C rating.
For example, if you have two 10Ah lipos, both with a 10C rating, then individually they are each rated for 100A
- 10Ah * 10C = 100A max
Put them together in parallel, and their combined rating is 200A.
- 100A + 100A = 200A max
However, thatâs still only 10C for the combined pack. You might think that 200A should now mean 20C. After all,
- 10Ah * 20C = 200A
But thatâs not how the math works out. When you put packs in parallel, you are not just combining their current potential, youâre also combining their capacity.
So the proper math for the two packs in parallel is
- (10Ah + 10Ah) * 10C = 200A
- which simplifies down to
- 20Ah * 10C = 200A
Hopefully this explains why, yes, you are doubling the current potential, but NOT their C-rating

So still nothing. No advice related to my question was given and no evidence of all this wisdom I refuse to listen to. All I see is running when called on ur bullshit claims. @BenjaminF
Awesome that is exactly what I was looking for!
That makes sense, the relationship between the AH and the Current rating.
When it comes to Series instead of parallel, Output current is not doubled, Is there something that does get doubled in series? Or does that tie back into just having higher voltage?

is it true C ratings are not always accurate/inflated? how can u double check
