QH Battery: Why Choose LFP Technology?

QH Battery prioritizes safety and quality, ensuring exceptional performance and extended cycle life for our batteries. We have established a strategic partnership with a reliable and advanced lithium battery manufacturer to secure a consistent supply. Among various chemical options, our primary focus is on LFP (Lithium Iron Phosphate) technology, which we consider the optimal choice for material handling applications.

Why Square Lithium Batteries are Preferred for Forklift Batteries?

Square lithium batteries have become the preferred technology for material handling equipment due to several advantages:

1. Higher Nominal Capacity: This technology offers the best power-to-energy ratio per unit volume. Material handling equipment requires batteries with high capacity, high current, and relatively low voltage, making square lithium batteries an ideal choice.
2. Optimal Utilization of Battery Pack Space: Square lithium batteries eliminate voids inside the battery pack, maximizing the pack's capacity. This provides additional space for weight, sealing elements, heaters, internal chargers, or other battery upgrades.
3. Robust Contact Connections: The busbar contact points in square lithium batteries are reliable and secure, making them suitable for high-vibration operations, particularly critical for cushion-tire forklifts.
4. Flexible Battery Weight: Unlike passenger electric vehicles, the weight of a lithium battery pack does not limit its range per charge in most material handling equipment. Forklifts primarily operate near charging stations, allowing the battery weight to be optimized for balance.

Advantages in Capacity and Cycle Life:

Lithium battery chemistries, including LFP, offer higher energy density compared to lead-acid batteries. QH Battery specifically chose lithium-ion technology due to its significantly higher energy density when compared to current lead-acid solutions. Our primary chemistry, lithium iron phosphate (LiFePO4), provides a specific energy of approximately 110 watt-hours per kilogram, while lead-acid batteries offer only around 40 watt-hours per kilogram. As a result, our batteries weigh approximately one-third of their lead-acid counterparts with the same ampere-hour rating.

Cycle life is another crucial factor. Different battery chemistries are affected by the depth of discharge, with deeper discharge shortening the battery's lifespan. Our lithium-ion batteries can be safely discharged to 80% depth while still maintaining a long cycle life of over 3500 cycles. In comparison, lead-acid batteries experience a significant decrease in cycle life when discharged to 80%, offering only 1000-1500 cycles. This highlights that our batteries have a three times longer lifespan than lead-acid batteries under similar discharge conditions.

SPEED & EFFICIENCY

QH Battery offers exceptional speed and efficiency with our advanced lithium-ion batteries. Our batteries are designed for fast charging, allowing for complete charging in a significantly reduced time. With ultra-fast charging capabilities of up to 1C, you can achieve a full charge in a fraction of the time compared to traditional lead acid batteries. Unlike lead acid batteries, which experience a dramatic drop in charging current after reaching 80% charge, our lithium-ion batteries maintain stable performance throughout the charging process. They can handle high discharge rates of up to 3C continuously or 5C in pulsed mode without compromising performance. Unlike lead acid batteries, which suffer from voltage sag and capacity reduction, lithium-ion batteries provide a consistent voltage and power output throughout the discharge, ensuring optimal performance even when the battery charge is low. Additionally, our lithium-ion batteries are free from memory issues, allowing you to discharge and charge them at any point without any negative impact.

SAFETY & RELIABILITY

When it comes to safety and reliability, QH Battery stands out with our carefully chosen lithium iron phosphate (LiFePO4) chemistry. LiFePO4 batteries offer three key advantages that make them the ideal choice for demanding applications:

1. Thermal Stability: Our LiFePO4 batteries are thermally stable, even at high temperatures, eliminating the risk of thermal runaway. With the ability to operate safely in ambient temperatures of up to 55°C (131°F), our batteries outperform lead acid batteries, which experience an 80% reduction in cycle life when operated under such conditions.
2. Long Cycle Life: QH Battery's LiFePO4 chemistry provides an impressive cycle life compared to other alternatives. While lithium titanate batteries may be costly and lithium nickel cobalt aluminum oxide chemistries can be unstable, LiFePO4 strikes the perfect balance of longevity and stability.
3. Power and Energy Density: Our LiFePO4 batteries offer superior power and energy density, surpassing lead acid batteries and many other lithium chemistries. This makes them an excellent choice for demanding tasks and efficient energy storage solutions.

At QH Battery, we understand the importance of safety standards. Our batteries are designed to meet or exceed UL certification requirements, ensuring the highest level of safety and reliability.
