As security becomes a greater concern in both urban and rural environments, solar-powered surveillance systems are emerging as a practical solution for remote monitoring. These systems are widely used in farms, parking lots, construction sites, and other off-grid areas where power access is limited. A critical component of every solar-powered surveillance system is its energy storage—and that’s where lithium batteries come in.
At Himax Electronics Co., Ltd., we specialize in the development and supply of custom lithium battery packs for solar monitoring systems. Our clients across North America, Europe, and Australia rely on us for dependable battery solutions that ensure stable performance in various outdoor conditions. But why are lithium batteries such a perfect fit for these systems? This article explores the key reasons and technical advantages in simple, clear terms.
1. Reliable Power Storage for Day and Night Operation
One of the main challenges of solar-powered equipment is energy fluctuation. While the sun can generate power during the day, the surveillance system still needs to operate at night or during cloudy weather. This is where a dependable battery becomes essential.
Lithium batteries, especially LiFePO4 (Lithium Iron Phosphate) types, are known for their high energy density and stable voltage output. They can store enough power during the day to keep the camera and communication systems running all night. Compared to lead-acid or NiMH batteries, lithium batteries can deliver consistent voltage over longer periods, ensuring uninterrupted surveillance.
At Himax, our most popular battery configurations for solar monitoring systems include:
3.7V 10Ah Li-ion battery packs
12V 20Ah or 50Ah LiFePO4 battery packs
25.2V 15Ah Li-ion battery packs (21700 cells)
Each pack is custom-made based on your equipment’s voltage, size, and current requirements.
2. Longer Lifespan in Harsh Outdoor Environments
Solar-powered surveillance systems are typically placed outdoors in extreme conditions—ranging from freezing winters to hot summers. This requires a battery that can withstand wide temperature ranges while maintaining performance and safety.
LiFePO4 batteries are especially suitable due to their strong thermal stability and long cycle life. Most Himax LiFePO4 packs operate between -20°C and +60°C, making them reliable even in deserts, mountains, or coastal regions. They also have a life cycle of 2000+ cycles, much longer than traditional lead-acid batteries that degrade after 300–500 cycles.
This long lifespan reduces maintenance needs, saving cost and effort for system owners—especially important in remote installations.
3. Lightweight and Space-Saving Design
When installing surveillance systems on poles or walls, battery weight and size matter. Heavy batteries require stronger mounting and increase installation complexity.
Lithium batteries are much lighter and more compact than lead-acid batteries with the same capacity. This allows the entire solar monitoring system to be smaller, neater, and easier to install.
For example, a 12V 20Ah LiFePO4 battery from Himax weighs around 2.5kg, while a similar-capacity lead-acid battery could weigh over 6kg. This compact design enables manufacturers to offer sleek, integrated camera units with solar panels and batteries all in one.
4. Fast Charging and High Efficiency
Solar-powered systems rely on efficient charging during limited daylight hours. The battery must be able to absorb solar energy quickly and efficiently before sunset.
Lithium batteries have a higher charging efficiency (over 95%) than lead-acid (around 70–80%), which means more solar power is stored in less time. They also support higher charge and discharge rates, making them well-suited for systems with varying power loads such as PTZ (Pan-Tilt-Zoom) cameras, motion sensors, and wireless transmitters.
Himax lithium battery packs come with smart BMS (Battery Management System) that optimizes charging performance while protecting the battery from over-voltage, over-current, and temperature issues.
5. Environmentally Friendly and Safe
More companies and governments are focusing on eco-friendly solutions. Lithium batteries are cleaner and safer than other battery types.
LiFePO4 batteries contain no toxic heavy metals and are easier to recycle. They are also chemically stable, with low risk of explosion or leakage, making them ideal for unattended installations in public or wildlife areas.
6. Smart Customization for Unique Projects
Each surveillance system is different. Some require high-current output, others need compact designs. This is where working with a custom battery manufacturer like Himax adds real value.
We work closely with our clients to design custom battery packs that fit their system’s housing, match voltage and current needs, and include the correct connectors (such as DC5521, XT60, or Molex).
We also support features like:
USB-C charging
Waterproof casing
LED power indicators
Built-in heating for cold climates
This customization allows our customers to launch products faster, reduce design errors, and improve end-user satisfaction.
