In industrial and medical applications, reliability under extreme conditions can make all the difference. The Tefoo Energy GS4040FL and GS4040IL smart batteries are specially designed to perform reliably even at very low temperatures down to -40°C—a feature that sets them apart from many standard lithium-ion packs.
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 fuel gauging 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.
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°C. The temperature range is 0 to 60°C for charging, but -40 to 60°C for discharging. Although the maximum peak current and SoC measurements are slightly less accurate under these conditions, the packs remain operational and reliable.
Technical specifications:
- GS4040FL (3S2P): 10.8V, 5400mAh, dimensions 150.0 × 58.5 × 22.0mm, approx. 355g
- GS4040IL (3S3P): 10.8V, 8100mAh, with dimensions of 214.0 × 58.5 × 22.0mm, approx. 510g
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.
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't be a problem.
