I have been learning about lithium batteries and how to refurbish and build battery sets for various applications.
- For Power tool batteries.
- For packing my own batteries for off-grid solar set-ups.
- So I can refurbish other peoples tool batteries.
- To convert appliances (flashlights) from NiCad to Rechargable Lithium cells.
I bought a Spot Welder from China
I got it off AliExpress. I found it was recommended from this Youtube Video:
Here is the description (from seller)
Description
The welding process is based on the principle of high current and high temperature, rapidly melting part of thespo nickel sheet, and cooling. This spots welding machine is 3 pulses design, high power and 99 output power adjustable for more accurate welding, suitable for continuously welding thousands of points on nickel/nickel-plate sheet. It supports welding 0.1-0.3mm nickel sheets with solid and beautiful welding spots. This product needs your own power supplies, support 12 V 20AH-65AH, the working current of power supplying equipment is about 100A-900A, support welding 0.1-0.3mm nickel-plated sheet.
Features:
The welding process is based on the principle of high current and high temperature, rapidly melting part of the nickel sheet, and cooling, can fully meet the requirements of small spots welding machine.
3 pulses design, 99 gear adjustment, simple operation, high conductive performance and nice heat dissipation, can work continuously for a long time.
This version has a fan interface, which turns on when the temperature exceeds 45 degrees, with fixed buttons and display on the motherboard for easy adjustment. Display languages of Chinese and English can be switched, the default automatic welding mode.
Built-in early warning protecting mechanism, intelligent control, support for welding 0.1-0.3mm nickel or steel strip, stable quality, welding solid, to avoids blowing up the tube.
Built-in 12*MOS tubes, the spots welding peaking current is up to 3600A, welding more firmly and more widely.
Pure copper conductive heat conduction, greatly improve the efficiency of spots welding.
Double-sided outgoing lines, easy to spots welding, the product is marked, not easy to connect the wrong.
Common Working Power Supplies in the Market: 30Ah-35Ah capacity lithium battery packs, 12 V car starting power supplies, 2S/3S/4S model aircrafts lithium battery packs, 3 string high rate lithium battery packs, 2.7V 3000F Faraday capacitor two in series, 12-14.6 V leadacid batteries, 12 V 30-65A stable performance leadacid bottle, high rate lithium iron phosphate batteries.
