Bảng Mạch Pcb Pin Lithium 18650 / 26650 / 32650 Chuyên Dụng

Tips:
-The package include should be spare parts, which need welding and assembly by yourself
-And it also need you to have some welding technology and circuit knowledge.
-Please mounting the capacitor to avoid the board burn and other issue before use.
(ps: The 12V spot welder’ capacitor has been welded to the board in advance.)

Used for welding 18650/26650/32650 lithium-ion batteries, advantages: portable, stable and reliable, durable.

Users need to bring your own 12 v battery power supply, welding current is 90 a ~ 130 a, for common 0.1 mm ~ 0.12 mm nickel plated piece of welding.After several generations of product updates, now it is upgraded to automatic trigger welding, liberation button on the finger.

Note:
If the battery is pretty good and the internal resistance is very low, and then there may be large current overload.
If you are not sure about your battery, it's better to extend the wire by around 1 meter with 2.52 or 42 wire, then it will reduce the risk of power tube burnt.

Below is for 12V spots welding kit
Specification:
- Can be welding 18650/26650/32650 lipo battery, it is portable, stable and reliable
- System voltage: 12V-14.6V
- Working current: 90-150A

Suggested battery:
- 20-45ah Lead-acid battery with good performance and small internal resistance
- 3.5-5.5ah 45C 3S aeromodel lithium battery pack
- 30-35ah capacity 18650 battery pack
-This circuit with a 12V battery will become an energy storage spot welding machine for welding nickel pieces such as lithium batteries and nickel-chromium batteries. According to different configurations, the thickness can be about 0.1MM-0.15mm

1set 12v spots welding kit include:
1pcs x Main Circuit Board
1pcs x Buzzer
2pcs x Input Wire
2pcs x Output Line with Welder Pen

Below is for 3.7V spots welding kit
Specification:
- Equipped with 3.7-4.2V 4.5ah power lithium battery, with a discharge rate of 100C and a load capacity of about 400A,
- Through the MOS tube output, this energy will be collected at the end of the solder pen, and the nickel sheet will be fused with the battery firmly by means of short circuit heating. All this will happen in milliseconds, controlled precisely by the microcontroller program, and no trigger switch required
