Warning:<\/strong> Lithium Ion and Lithium Polymer batteries can catch on fire if shorted, punctured or overheated. Before you solder the terminals, plan your wiring. Strip and tin the wire ends. Peel back one of the battery terminals.<\/p>\n With a small file, roughen the outer half of the battery tab.<\/p>\n Fold the end of the battery tab over, to create a small \u2018hook\u2019. Put a tiny drop of flux in the hook. Place the wire into the hook – making sure it matches the polarity – and press it closed. Carefully, press the soldering iron against the folded hook. Run the solder into the folded hook until it begins to melt and \u2018wet\u2019 to the metal. Roll the tab up until it is inside the battery sled. Repeat for the second battery tab and wire.<\/em><\/p>\n Once both tabs are soldered, the wires can be fixed in place with hot glue, and the area covered with a small quantity of masking tape.

This could also be done using a battery spot welder, clamping, or screwing. Warning: Lithium Ion and Lithium Polymer batteries can catch on fire if … Continue reading
\nBe careful when soldering that the battery does not become hot.
\nEnsure you have an appropriate fire extinguisher nearby.\u00a0<\/em><\/p>\n<\/div>\n<\/div>\nStep 1: Wire Prep<\/h1>\n

\nWhere should the battery wires exit the battery? In what direction will they go, and how far?\u00a0(A scale printout of the layout may help)<\/em><\/p>\n
\nEach bare end should be slightly shorter than the battery tab\u2019s width.<\/p>\nStep 2: Tab Prep<\/h1>\n

\nIt should be just large enough to fit the wire in.<\/p>\n
\nYou can spread it around with a piece of wire.<\/p>\nStep 3: Soldering<\/h1>\n

\nIt may help to clamp a little bit of the insulation in the hook as well.<\/p>\n
\nThe aim here is to heat up the tab, the wire and the flux, without heating up the battery.<\/em>
\nIf the battery near the tab is warm, stop and wait 2-3 minutes before attempting again.<\/p>\n
\nAs soon as it seems that a good contact has been made, stop. The\u00a0solder should have bonded well to both sides of the hook, and to the wire as well.<\/p>\nStep 4: Tidying<\/h1>\n
