Thanks for the reply. After three months, the silver adhesive is performing well. The Orion BMS 2 only puts 50mA through the cell tap connection.One of your questions in the video was related to BMS wire attachment.
There are some silver filled epoxies on the market that I have used for connecting wires to contacts that were not solder compatible.
I used them back when LED domes were not capable of handling solder temps as a way to attach the LED thermal path to a heat spreader.
I tested a few types for durability by throwing completed assemblies up in the air as high as I could, and letting them crash land on a concrete driveway. The other test was to throw them as hard as possible at a concrete wall from a short distance. At that time I could throw a baseball ~ 50 - 60 mph.
My very crude experiments indicated that epoxy mixtures optimized for toughness performed better (in this test) vs those optimized for adhesive strength.
All of the ones that I tested performed pretty well - if fully cured. Check the full cure temperature requirements for your application.
Pre cleaning with pharmacy grade iso propanol had a much greater effect than the difference between materials.
I didn't test the electrical properties in any detail, because they all performed more than sufficiently for what I needed. (about 2 amps)
They all had odors and some resulted in a bad headache, so use a LOT of ventilation. I thought that I had plenty in the garage but it wasn't enough.
