I bought 4 X VTC6 batteries that were installed[In house] with a Stainless Steel BT. Not a solder blob or Third party BT. Liionwholesale will do it for Only $2/battery for any FT you want. They do have several third party BT batteries.
It got me thinking. First I asked HKJ, then did my own brief research on the BEST metals for conductivity and finally contacted Jon, owner[and engineer] of Liionwholsale to get his take.
HKJ did not do tests on this. He just questioned whether 1.5mm of BT would make a difference? I took it that it would not be significant.
Jon from Liionwholesale did test it: Not quoted,his general words.
He said he tested AC inductance and saw around 13.5 mOhm or so with the button top. Without the button top it’s around 13 mOhm, so it’s really rather negligible.
And for me, I did learn some simple stuff.This is from a website.
Best metals for conducting electricity:TOP 13
Pure Silver,Pure Copper,Pure Gold,Aluminum,Zinc,Nickel,Brass,Bronze,Iron,Platinum,Steel,Lead and in Last place was Stainless steel.
Oh yes,It was a 4 year old thread on here[when I googled SSBT] That got me started on this:Last post #15
Would my SSBT reduce current flow with a noticeable loss of Output? My guess is neglible.
What do you guys think?
PHOTOS of batteries below. They tested an average of 3027mAh on my Opus BT-C3100 2.2
