2 Section 32650/32700 Lithium-Ion Battery Support Bracket made of flame retardant ABS+PC materials, with high-temperature resistance and crack resistance. There are slots on the edge of the holder that can be combined to create a battery pack of many different sizes and shapes; after welding nickel tabs, the pack can pass vibration testing without using any other connecting device that makes your battery pack Solid and Reliable.
32650 (32mm diameter and 65mm Length) is one of the most common cell sizes for lithium iron phosphate (lifepo4) batteries found worldwide. So it can be easily replaced in any battery-powered application. We need many cells to build a battery pack to power the high power devices like your laptop, small RC cars, or even any small Digital circuit with many sensors and actuators.
