Travel multicharger 2-3-4S

thingiverse

I created this charger because I had several Hobbyking chargers and when it came to charging they took up a lot of space on my table and had numerous cables scattered everywhere. The box consists of a 10A to 12V power supply and 6 Hobbyking 2, 3, and 4S chargers with input voltage between 9 and 16V. It also has 2 USB charging ports with 1 and 2A and 4 fans that efficiently extract the heat generated during charging. The power supply is separated from the charger area to allow for independent cooling. It features an EC5 connector, which can be used in conjunction with a car cigarette lighter cable to charge LiPos using the car battery. A 3 position switch enables selecting AC current, off or car battery, and a voltmeter allows monitoring of the input source voltage. With this power supply, the voltage drops to 9V when charging multiple batteries simultaneously, but still charges correctly. The design includes 2 switches that control fan operation in the power supply or charger areas. In my case, I removed all speakers from the chargers as they produce a cacophony of beeps when multiple batteries are being charged at once. Viewing the screen's flashing display is sufficient for me to determine charging status. I have uploaded the design file so that anyone can modify it to their liking. **Required Components:** * Power supply 12V and 10A https://banggood.app.link/ZKR1NvlUUZ * 6 Hobbyking chargers (similar to those found at Banggood) https://hobbyking.com/es_es/hobbykingr-dc-4s-balance-charger-cell-checker-30w-2s-4s.html * 6 connectors 5.5X2.1mm male right angle https://s.click.aliexpress.com/e/2vmG6xKu * 1 switch 3 positions https://s.click.aliexpress.com/e/5qaU3XUU * Plug C8 male https://s.click.aliexpress.com/e/BbskJRfw * 4 fans 40x40mm 12V https://banggood.app.link/LLPMF1aUUZ * 3M threads (many) https://banggood.app.link/chxwBCqUUZ * Battery connector EC5 https://s.click.aliexpress.com/e/FynSvSks * Cigarette lighter adapter cable https://s.click.aliexpress.com/e/qq6MRmiU * C7 plug cable https://s.click.aliexpress.com/e/qV7fzO5E * USB 2 Port Charger Board https://banggood.app.link/WWJ7IWCJVZ * Voltmeter 2.5V-30V https://banggood.app.link/KE3vLMGJVZ
