This picture is the previous_test_version battery but not stably enough
Now I make the new version battery.
-First, the Li-ion battery buy from the taobao, it is very cheap. (18650 2400mah 5C 3.6V Lion 6.5 CNY/PCS)
-Putting all battery into 18650 bracket. If feel setup difficulty. You can use soft hammer haha
-Watch out!
1.The electric potential difference should not exceed 0.05V.(boooom😛)
2.When you do the spot welding ,don't short the battery it will explosion💥
-Staring spot welding process by self making spot welder.
-Finish the spot welding , setup and solder the battery protector to the batteries.


-Finally, Using the thermal film to package the battery

-COMPLETE! HAHAHA💥
