I need a precise, low-resistance solder joint made on the battery leads of my drone. The task is straightforward: take the existing electrical wire coming from the battery pack and solder it securely to the designated battery connection pads/connector on the airframe. A clean, shiny joint with proper strain relief is crucial so the connection can handle both current spikes and the vibrations that come with flight. Bring whatever tools you feel most confident with—a temperature-controlled iron, fine rosin flux, decent solder (60/40 or lead-free is fine if you’re comfortable), and heat-shrink tubing for insulation. Once the joint is complete, I’ll do a quick continuity and voltage drop test; as long as it passes and looks solid, the job is done. If this is something you can knock out quickly, let’s set up a time.

Hi I am an embedded systems engineer with over 12 years of experience. I have extensive experience with RC/drone electronics, high-current battery wiring, clean soldering on pads/connectors, insulation, and strain relief for vibration-heavy assemblies. This is a straightforward job and I can handle it carefully: clean and tin the wire/pads, use proper flux and suitable solder, make a shiny low-resistance joint, insulate it with heat-shrink, and make sure the lead is mechanically supported so it is not relying only on the solder during flight vibration or current spikes. I am also comfortable checking continuity, polarity, and voltage drop before considering it done. Please contact me to discuss details and set up a suitable time.

I am an electrical engineer have done my engineering from dha suffa university.I have four years of experience in the field of electrical engineering.I have implemented on proteus software to electronic circuit design to make pcb design by iron soldering to iron wire to solder component for proper making on pcb.. I have implementation and working of pcb design in which i have solder component to create a iron wire path to make a circuit by connecting the equipment by wire using a iron wire and to make the circuit square shape ready to run conduct and work in a well mannered condition by giving a jumper wire ending output. I am looking forward to work with in solder the battery to desolder it which is causing a lot of trouble can possibly damage if not unfixed an than solder it to the circuit to ensure proper connection has been fixed and in working with you. Regards, Hasan Abdul Wasae.
