Temperature changes affect your LiPO battery in many ways. When it is very hot or cold, the battery does not last as long. It also cannot hold as much power and will not live as long. High temperatures make the inside parts break down faster. This can make the battery swell or even catch fire.
You can expect a 3.7V lithium-ion battery to last about 2 to 3 years. It usually handles between 300 and 1,000 charge cycles before you notice a drop in performance. How long your battery lasts depends on how you use and care for it.
C rating looks like a small label, yet it controls big outcomes. It tells you how much current a LiPo battery can deliver safely. Many buyers focus on voltage and mAh first. They forget discharge capability. Then the pack runs hot, sags hard, or ages fast. Those issues show up in RC, drones, robotics, and power tools.
