Where did you source your Li battery from? Also, what kind of spot welder is that ? And where did you source it from? Thank you

This battery can be bought on aliexpress or amazon. And this spot welding can also be bought on aliexpress. This spot welding is designed for various types of batteries. But the battery can be soldered using soldering. But quickly and accurately obtained using spot welding. You will find links for spot welding and batteries on my other KZbin channel attached to two videos on the links. Spot welding from AliExpress kzbin.info/www/bejne/eoK9o2ejoceZpJY Litium baterys from ALiExpress kzbin.info/www/bejne/f3vPpHyondp7rdE

Hello, I have the same one and the batteries are dead. I will install the battery in the drill directly to the battery with the support.

Hi. Good idea, but don't forget about the battery's current output speed.

@ I want to use batteries that I took out of scrap laptop batteries, what are the V ranges that can be used?

[@repairandinvention6224]

@@huseyintural3749 You can try a laptop battery since this drill is not that powerful. The C rating of a battery indicates its discharge rate relative to its capacity. To calculate it, use the formula: C rating=Battery capacity (Ah)/Time (hours). For example, a 10Ah battery discharged in 2 hours has a C rating of 5C. The nominal rating for a 18650 battery is usually around 2850 mAh, or 2.85 Ah. In simpler words, a 18650 battery rated at 2.85 Ah is capable of providing a current of 2.85 amps for a duration of 1 hour. Alternatively, it can supply a smaller current of 0.285 amps for a longer duration of 10 hours. At 10C the battery should be suitable for a drill.
