Solder Lithium Batteries Into 15 E-Cigs

I have fifteen first-generation “cigalike” e-cigarettes that still work electronically but their original cells no longer hold a charge. I’ve sourced the exact size lithium-ion replacements, so what I need is a steady-handed technician who can:

• Desolder each depleted cell cleanly
• Solder in the new lithium-ion battery without damaging the thin leads or plastic shell
• Re-assemble the body so it snaps closed as originally intended
• Verify each unit charges and fires correctly before returning them

All fifteen batteries and devices are ready to ship to you immediately; you supply the tools—fine-tip soldering iron, ESD mat, flux, heat-shrink, and any protective fixtures you like. I care most about neat joints, reliable connections, and zero cosmetic damage, so please be comfortable working on very small PCB pads and tight housings.

Once you’re finished, a short record of the charge test for each unit (voltage after full charge + quick activation) will serve as acceptance criteria. Let me know your turnaround time and how you prefer the devices packed for safe return.
