Emergency rescue started power supply after half a year

September 4, 2024

At first, lithium batteries were not attractive to them. If they were used twice and put them aside for a long time, the batteries would be bloated. I wanted to buy an electric treasure made of super capacitors, but the price was too expensive, 799 yuan. I couldn’t afford it, so I made it myself. I used a hole board for flying wire welding. Although it could be used after finishing, the internal wires really looked scary.

Later, it was changed to PCB production and more advanced single-chip computers. The display screen was made of digital tube and OLED screens. It has more functions than the 799. It can ignite cars with a 0V battery or no battery at all.

No need to fly.

Later, some additional functions were added, such as automatic discharge detection of engine ignition, electrodeless dimming LED lighting, hardware shutdown, and overheating protection functions, so that short circuit protection, reverse connection protection, overvoltage protection, overcharge protection, and overheating protection are complete.

Yesterday, an equalization circuit and a vehicle-mounted function that is fixed and connected to the battery were finally added. For a long time, people have often connected the battery to use it in parallel, saying that it can greatly extend the battery life, improve audio quality, and improve spark plug ignition stability, etc.
