In this video, I show you how to add a Rechargeable battery to a Nerf gun. In this case is the Fortinite B-AR Elite Nerf. I use: · 16850 3.7v battery · A battery holder · MT3608 board
Warning: Do not follow this "guide". It plays fast and loose with current "measurements" eyeballed from a power supply while using a no-name 18650 ICR; that's a great way to have the battery catch on fire. The only saving grace is that the thin wiring will probably desolder itself first from all the heat of carrying that much current, though that risks shorting the li-ion cell, which would definitely create a fire.
I don't see any issue with the set up the circuit I use limits current to 2A. There is no short circuit danger as everything is fixed. The current is limited by the motors. Never pass and never pass the limits of the circuit. I don't exactly understand what risk are you talking about
The most risky thing about this is the soldering other than that its pretty safe provided you know what youre doing. Precautions like not burning yourself or inhaling solder fumes, testing your batteries before you use them, cleaning up your mess, avoid operating in high heat. These things can help mitigate any risk and the diy community thanks you for your concerns. I would like to add that many consumer grade products are considered "generally recognized as safe" (GRAS) and that doesnt mean they always are, hence recalls. Always wear ppe and exercise caution when you diy anything.
