The car remote control has been converted to lithium battery, so exciting! [Copy link]

The ordinary batteries I bought for the Xiaosan remote control ran out of power after a short time, which was very depressing! I thought about it over and over again but there was no good solution. One day, I saw a Bluetooth headset that I had given up, and I suddenly thought, could I use its lithium battery? I picked it up decisively and disassembled it! Remove the battery, remove the contacts of the remote control battery pole, identify the positive and negative poles, and weld the wires! Install the shell and test the machine! More than 50 meters is no problem! Important reminder: It is best to have a protection board for lithium batteries, car remote controls are very expensive!
