I’ll just dump water on it
I know that 400c all too well, yet still I find it underwhelming , do you have that same experience?
I do. you only need 4 cells?
Is a lot better than a 15 watt anal stick I was using before to solder I can say that much…
Just did about 9 twelve gauge phase wires in a row and filled em like a champ. I’m using a pound of kester solder (stuff from amazon that is highly recommended and costs like 30$ a reel) so that helps as well for sure.
Lol. Yea I have 12 4p groups already spot welded. Need one more for 13 and then need to get it built.
I was gonna ask you but I read that you onto build if other builder can’t or are busy etc. Figured I’d ask around but if I can send you the p groups would you be able to put together a pack.
I’ll PM you.
Yeah I can assemble them, got plenty of supplies here
Or should I just make/mod in a ‘pressure connection’ similar to how people use these braided copper ground wires with the NESE systems or others similar where they just sandwich the cell terminals in between two of the straps and some plastic connectors @Fosterqc

Thanks man. I sent you a PM
I’m looking for help with some bms questions. The specific unit is this one - https://www.litechpower.com/product-detail/HCX-D503V1LI12S15A_01.html#
In the picture below I’m guessing that’s an antenna of some sort. Can someone confirm? If so that would imply Bluetooth or other connectivity which implies an app or other software interface. But I don’t see any mention of this on the product page. I don’t need or want an app for what I’m doing. Can anyone confirm if I can use this for charge only without any software or app based configuration?
Thanks!
I believe that is a temperature probe, however not certain
Didn’t even consider that but it makes total sense. I’ll investigate that further. Thanks!
It’s a temperature probe.
Did you calibrate it? Mine was like 20c off out of the box
And flux 
thats just braided uncoated copper wire as i know
Yeah, but appears to be less dense than the braid most of you guys use, I guess I will buy some, twist it tightly and measure to see what AWG equivalence I get
Solder wick is considerably thinner, and I wouldn’t expect  equal consistency over it’s length or material purity since none of those things really matter for it’s purpose
Think of it as the braid that didn’t make it to graduation 
Uploaded the new FW, might need to callibrate the temps though.
It can be done, but there are better, cheaper options - Solder wick is not tinned for corrosion resistance, and is usually impregnated with flux to help it wick solder, which is undesirable for use as a flexible bus material.
It’s also a lot thinner than what most pack builders use - I use flat tinned ground braid that’s the equivalent of 10AWG.
I will have to use a bunch of it them, I’ts to join each 5P group, I guess I can easily use 10 strips
