The problem is, I do not know how conductive the "conductive" glues are. Do they introduce a few mΩ resistance? Is it a few, a few 10s or a few 100s? Is it enough to cause a noticeable voltage drop and hence problems at higher currents?

I personally would solder. The "battery" contacts are not actually directly contacting the battery, there is a tiny circuit board between the battery and the terminals. But I would be extremely careful not to overheat the board while soldering, as even the transferred heat might be enough to permanently damage the battery (trust me, I know - and I have been soldering things for 30 years ). For the less experienced, a glue is a less risky solution.

I agree, it might add too much resistance, and either over heat, or the battery or phone will plain refuse to work due to low voltage

(It's the one which cares about battery security - like shutting down when over charging, voltage under safety point - and talks to the phone over I2C to give battery health information (all the data you can see in CSD)

It might not be *directly* in contact with the battery, but still, they are dangerously close to the lithium.
One wrong movement with the soldering iron or on badly landing drop of solder and you're in for a tiny firework.

The best would be to ask a friend with lots of experience and a steady hand.

The R&D of Keyboard Mod will finish in 10 days. I will be back to China for various things but this will be one of the most important subject. Hopefully when the Keyboard Mod ships I will prepare some hand cast samples of this unit. We are making progresses. (With the new robust 8-string sliding part, also off-set keypad etc.) Will resume updating in coming weeks.

I personally got more excited with the going of this device, and technically speaking (OS aside) it's somehow much easier than Moto Mods platform.

No worries. Take your time. Enjoy China.
