Wiltson Energy and Our Low-Temperature Technology

Wiltson Energy focuses on advanced lithium iron phosphate (LiFePO₄) batteries. Our low-temperature series, LT3500 (3.2V | 3.5Ah), is designed to work directly in extreme cold conditions without heating. Traditional lithium batteries often lose capacity in freezing weather, but Wiltson batteries keep a high discharge efficiency even at $-30^\circ\text{C}$, and still perform reliably at $-50^\circ\text{C}$. This breakthrough makes sure robots, forklifts, and sensors can keep running smoothly in cold environments without extra heating systems.

Solving Challenges in Industrial Automation

In cold regions and freezer warehouses, battery performance often drops sharply. Regular LiFePO₄ batteries can lose nearly half their capacity at $-20^\circ\text{C}$, and charging can even damage the cells. Lead-acid batteries do even worse, with usable capacity dropping to about 45% at $-18^\circ\text{C}$.

Wiltson’s LT3500 low-temperature battery solves this. With optimized materials and design, it can charge and discharge quickly in freezing conditions. Unlike solutions that need heating blankets or insulation, our battery saves energy, reduces maintenance, and is ready to use right away. The natural safety and stability of LiFePO₄ chemistry also makes the system more reliable.

Value in Robots, Forklifts, and Automation

For industrial robots, forklifts, AGVs, and sensor networks, battery performance is critical. Wiltson’s low-temperature batteries bring several advantages:

• Higher energy efficiency – up to 99% output, compared with about 80% for lead-acid.
• Fast charging – fully charged in about 2 hours, with 15–30 min opportunity charging support.
• Lower maintenance – sealed design, no acid leaks, no water refilling, no gas emissions.
• Stable operation in the cold – delivers reliable voltage output even below freezing.

Case Study: Northern Germany Cold Chain Warehouse

A cold chain logistics warehouse in northern Germany upgraded its forklifts and robots with Wiltson LT3500 low-temperature batteries. Before, the machines struggled in $-20^\circ\text{C}$ environments. With Wiltson’s batteries, they now operate without warm-up delays and deliver stable power through long shifts.

The results:

• Energy efficiency close to 99%, reducing wasted power.
• Continuous 24-hour operation in freezing temperatures.
• Maintenance costs down by almost 20%.
• Safer working conditions with no acid mist or gas leaks.

The customer reported much higher productivity and reliability compared with their old lead-acid systems.

Other Advantages

• Long cycle life – about 1500 cycles, much longer than standard batteries.
• 5-year warranty – ensures stable performance over time.
• High safety – LiFePO₄ chemistry is stable even under stress, reducing fire and explosion risks.
• Eco-friendly – no toxic heavy metals, greener materials, and fewer replacements over time.
• OEM & ODM support – customized designs to match different robot and automation systems.

With Wiltson Energy’s LT3500 low-temperature battery, industrial robots and automation systems can run longer, safer, and more efficiently in extreme cold.
