Junda Battery’s low-temperature lithium battery packs are engineered to perform in extreme cold, with reliable discharge at -50°C and optional self-heating for safe charging below freezing. Designed for harsh outdoor, marine, and industrial environments, these battery systems maintain high capacity retention and offer waterproof, ruggedized enclosures built to last.
Junda Battery offers advanced low-temperature lithium battery solutions specifically designed to operate reliably in harsh, freezing environments. Whether your equipment requires discharge at temperatures as low as -50°C or charging below 0°C, our low-temperature battery packs deliver stable power with high capacity retention.
Thanks to built-in self-heating technology and IP68-rated waterproof protection, Junda’s low-temperature batteries can safely charge even at -20°C. This makes them ideal for outdoor, remote, and mobile devices exposed to extreme cold.
Junda’s low-temperature rechargeable batteries are widely used across demanding applications that require durability and performance in sub-zero environments. We offer custom pack sizes, shapes, and capacities to match your system requirements.
Proven in sub-zero field deployments, these projects demonstrate how Junda’s low-temperature LiFePO₄ battery packs support stable performance in extreme cold — from -20°C to -50°C — across marine, medical, and mobility sectors.

Junda’s low-temperature LiFePO₄ battery packs can reliably discharge at temperatures as low as -50°C and charge below -20°C with built-in self-heating and IP-rated waterproof protection.
Yes. Many of our battery packs feature IP64 to IP68 waterproof housings, making them ideal for marine, outdoor, and industrial environments that experience freezing conditions.
Absolutely. Junda offers custom battery solutions with flexible voltage (3.2V to 51.2V), capacities (from 9.6Ah to 200Ah+), and physical formats to fit your device’s design and operating conditions.
Depending on the pack configuration and depth of discharge, most solutions offer 2000+ cycles at 80% DOD, even under repeated exposure to low temperatures.
Our batteries are widely used in RV power systems, trolling motors, buoys, medical devices, outdoor sensors, agricultural robots, and marine vessels deployed in cold climates.
With more than a decade of experience, Junda delivers precision-engineered lithium battery packs tailored for your unique applications. Here’s what makes us a trusted partner for global B2B clients:
