High-temperature batteries, such as high-temperature ER batteries and LiSOCl2 hi-temp batteries, are designed to operate in extreme temperature conditions. These batteries are commonly used in applications where traditional batteries may fail or perform poorly due to high temperatures. Additionally, round and custom LiPo batteries are popular choices for various electronic devices due to their high energy density and compact size.

Here are some key points about high-temperature batteries and LiPo batteries:

High Temperature Batteries:

1. High-temperature ER batteries: ER batteries, also known as lithium thionyl chloride batteries, are known for operating in a wide temperature range, including high temperatures. These batteries are commonly used in industrial and military applications requiring high-temperature resistance.
2. LiSOCl2 hi-temp batteries: LiSOCl2 (lithium thionyl chloride) are specifically designed to withstand high temperatures. They offer excellent performance and reliability in extreme temperature environments, making them suitable for downhole drilling, aerospace, and automotive.
