<h1>Risk Alert! Modify your controller at your own peril. I disclaim all liability for any resulting damage.</h1> Description for fearless experts who know exactly what they're doing: To proceed with confidence, you'll need a TP4056 Li-ion charging board with discharge protection built-in. Two ICR14500 Li-ion cells are also required. Additionally, a 1n400x diode is necessary to slightly lower the output voltage. You'll also need nickel strip, 6mm wide, an ss12d00g4 (4mm) toggle switch, and a self-tapping screw. The diode's purpose is to reduce the output voltage by approximately 0.7v. Since fully charged Li-ion cells reach 4.25v, this drop brings the final voltage down to around 3.55v - remarkably close to two new alkaline cells at 1.65v each. I initially ran my controller without a diode and it performed flawlessly under 4.25v, but for added safety, I decided to add one. Compared to NiCd batteries, this mod significantly extended the working time of my controller. Moreover, I can now plug in the charging cable at any moment and continue using my controller uninterrupted.
