Check the wiring on your recharge port. Use the manual for reference. Shtokyd knows his stuff so you're switch is fine on the ground. I was thinking about micro-usb setups. Here's an led calculator. ledcalc.com/ This one shows the actual value and the current your led will be getting. The nearest real world value can be used at your own discretion. Also remember that if you run resistors in parallel that you can split the resistance and double the wattage by doing so. This can help to get a value closer to what you really need. On the smd's that give you a range, I don't know what value to tell you to use. Go too big and the led barely lights up, if at all. Go too small and pop goes the led. This is where bench power supplies come in handy. Also, remember your source voltage. It's 3.7v on the main pads and 3.3v on the accents.
