Product Introduction
Howell 12V lithium battery (LFP – lithium iron phosphate) is a kind of new environmental-friendly backup power system product made by our self-developed core technologies. The product has great features of short-time and high-rate discharge (1C) and over 3000 times of cycle life. With a built-in BMS, the product is fully protected under high-voltage protection and featured with higher reliability. It also has impressive weight reduction and high integration which can save more installation space. The product has no memory effect and enjoys free maintenance, saving a lot of labor for people. In addition, it enjoys over 10 years of operational life. 12V lithium battery is a perfect replacement for the conventional lead-acid, AGM, gel batteries for its high performance and increased efficiency and can be widely used in many fields like camping cars, RV motorhome, golf carts, boat marine yachts, electric skateboard, LED backup, engine starting battery, mobile POS and mining light.
Frequently Asked Questions
Q
What type of battery chemistry does the HWE-4F20 use, and why is it better than lead-acid batteries?
The HWE-4F20 uses LiFePO4 (Lithium Iron Phosphate) chemistry, which offers significantly higher efficiency (99%), longer cycle life (over 3000 cycles), 100% depth of discharge, and no memory effect compared to conventional lead-acid, AGM, or gel batteries. It also requires zero maintenance and lasts over 10 years in operation.
Q
What is the maximum charge and discharge current for the HWE-4F20 battery?
The maximum charge current is 20.0A and the maximum discharge current is also 20.0A. The recommended charge current is 10.0A for optimal battery longevity, while the standard charge and discharge current is 4.0A.
Q
Can multiple HWE-4F20 batteries be connected in series or parallel?
Yes. The HWE-4F20 supports a maximum configuration of 2S4P, meaning up to 2 units in series and 4 units in parallel. This allows you to scale voltage and capacity to meet the requirements of your specific application.
Q
What certifications does the Howell 12V LiFePO4 battery hold?
The HWE-4F20 battery holds IEC62619 and CE product certifications, ensuring it meets international safety and quality standards. For transportation, it is certified with UN38.3 and MSDS, confirming it is safe for shipping and handling worldwide.
Q
What are the recommended operating and storage temperature ranges?
The HWE-4F20 battery operates safely within a temperature range of 0°C to 50°C. For storage, it can withstand temperatures from -20°C to 60°C, making it suitable for a wide variety of environments and climates.
Q
What applications is the Howell 12V LiFePO4 battery suitable for?
The HWE-4F20 is a versatile power solution suitable for a wide range of applications including camping cars, RV motorhomes, golf carts, boat marine yachts, electric skateboards, LED backup systems, engine starting batteries, mobile POS terminals, and mining lights. Its compact size (181×77×167mm) and lightweight design (3.0KG) make it easy to install in space-constrained environments.
