The Tefoo Energy GS4040FL and GS4040IL smart batteries are specially designed to perform reliably even at very low temperatures down to -40\u00b0C\u2014a feature that sets them apart from many standard lithium-ion packs.<\/p>\n\n\n\n<p>These hardcase-certified smart lithium-ion battery packs combine high energy density with advanced battery management via the SMBus v1.1 interface. An integrated microprocessor performs precise <em>fuel gauging<\/em> off, while built-in memory stores the specific cell characteristics and algorithms. This allows the host system to obtain real-time information on capacity, charge status, and temperature.<\/p>\n\n\n\n<p>While many batteries experience a significant capacity loss in freezing temperatures, the GS4040FL and GS4040IL retain up to 80% of their capacity, even at -40\u00b0C. The temperature range is 0 to 60\u00b0C for charging, but -40 to 60\u00b0C for discharging. Although the maximum peak current and SoC measurements are slightly less accurate under these conditions, the packs remain operational and reliable.<\/p>\n\n\n\n<p>Technical specifications:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>GS4040FL (3S2P): 10.8V, 5400mAh, dimensions 150.0 \u00d7 58.5 \u00d7 22.0mm, approx. 355g<\/li>\n\n\n\n<li>GS4040IL (3S3P): 10.8V, 8100mAh, with dimensions of 214.0 \u00d7 58.5 \u00d7 22.0mm, approx. 510g<\/li>\n<\/ul>\n\n\n\n<p>Additional features include cell balancing for extended lifespan, extensive safety features such as overvoltage, overcurrent, and reverse polarity protection, and an integrated LED charge status indicator. Thanks to the finger-type metal connector design, the batteries are easy to replace.<\/p>\n\n\n\n<p>With their exceptional freezing performance and broad safety and quality certifications such as UN38.8, UL, CE, the GS4040FL and GS4040IL are an ideal choice for applications where cold weather shouldn&#039;t be a problem.<\/p>\n<p>The message <a
