Im trying to power 2 - 1W high power LEDs for a sterilization device. Theres not much room and I am using a pico buck converter for constant voltage to drive the LEDs. I need to have a rechargeable battery that can put out the required 7 volts to drive the buck converter. Is there any options besides putting two bulky lithium ion batteries in series considering Im tight on space?
