Designed to securely house three standard 18650 lithium-ion cells, this holder is internally pre-wired in a series configuration. The moment you snap in three fully charged cells, the holder instantly combines their voltage to deliver a nominal 11.1V output (peaking at 12.6V), making it the ideal power source for standard 12V DC components.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eBuilt for prototyping and field deployment, the chassis is molded from rigid, high-impact ABS plastic. It utilizes heavy-duty, nickel-plated steel coil springs that maintain constant tension against the battery terminals. This ensures a solid, low-resistance electrical connection that won't momentarily disconnect if your hardware is subjected to bumps or vibration. Terminated with standard red and black pre-stripped wire leads, this holder is ready to be soldered straight into a 3S BMS protection board, wired into a custom PCB, or plugged into a testing breadboard.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eKey Features \u0026amp;
