eLeaf iStick TC40W 18650 battery replacement extension

thingiverse

If your TC40W's battery dies, you'll want to try to replace it. After cautiously opening the iStick case, you'll see a soldered LiIon battery and think as I did "Easy job: it's a 18650!"... Well, not so easy, because the original battery is not a 18650 (18mm x 65mm), but a 20600 (20mm x 60mm). So even if the 18650 diameter would be OK, there is not enough room in the length of the case for a 18650. So, I designed this small extension that sits between the top plate (where the atomizer is fitted) and the main body of the TC40W. After printing this, you'll have to: Change the two wires that connect the atomizer connector to the main PCB for longer ones: Use thick enough cables, if possible with silicone sheathing. Sand the interior of the screw tubes of the printed part as there are small bumps there on the interior of the top plate (see picture) Replace the two top plate screws by longer ones I printed mine in PLA as I never go over 15W and the plate doesn't heat. If that's not your case, use PETG. A word of caution: When disassembling or assembling your TC40W be VERY CAREFUL not to short anything as a 20600 or 18650 lithium battery is a dangerous device. I'm not responsible for anything happening to you, your house or the earth if you try this...
