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
What type of battery chemistry does the Howell 12V battery use?
The Howell 12V battery uses LFP (Lithium Iron Phosphate) chemistry, also known as LiFePO4. This chemistry is well-regarded for its superior safety, long cycle life, stable discharge voltage, and environmental friendliness compared to other lithium-ion chemistries.
Can the HWE-4F7 battery be connected in series or parallel for higher voltage or capacity?
Yes. The HWE-4F7 supports a maximum configuration of 2S4P, meaning up to 2 units in series (for higher voltage) and up to 4 units in parallel (for higher capacity). This flexibility allows users to scale the battery system to meet different energy requirements.
How long does the Howell 12V LiFePO4 battery last?
The battery offers over 3,000 charge/discharge cycles and an operational life of 10+ years under normal usage conditions. This makes it a highly cost-effective long-term investment compared to conventional lead-acid or AGM batteries that typically last only 2–5 years.
Is the HWE-4F7 battery safe for outdoor and marine use?
Yes. The battery carries an IP65 protection rating, which means it is fully dust-tight and protected against water jets from any direction. This makes it suitable for outdoor environments, marine applications, and other demanding conditions. It is also certified under IEC62619 and CE standards.
What is the recommended charging current for the HWE-4F7 battery?
The recommended charge current is 3.5A, while the standard charge current is 1.4A. The maximum allowable charge current is 7.0A. For optimal battery longevity, it is advised to use the recommended charge current and a compatible LiFePO4 charger with a charging cut-off voltage of 14.6V.
Can the Howell 12V LiFePO4 battery replace a traditional lead-acid or AGM battery?
Absolutely. The HWE-4F7 is designed as a direct replacement for conventional lead-acid, AGM, and gel batteries. It offers 98% efficiency, 100% depth of discharge, no memory effect, and zero maintenance — all while being significantly lighter and more compact. It is widely compatible with applications including RV motorhomes, golf carts, marine yachts, camping vehicles, electric skateboards, and engine starting systems.
