Custom Lithium Battery Solutions for Smart Pet Water Fountains

Smart pet water fountains are increasingly popular among pet owners because they provide a continuous supply of fresh, filtered water. Modern fountains often integrate pumps, filtration systems, sensors and even app-controlled features. For these devices, a reliable battery system is critical to ensure uninterrupted operation, especially in areas without constant access to power or during short-term outages.

PKNERGY offers high-performance, customized lithium battery solutions that meet the unique requirements of smart pet water fountains. Our packs are designed for safety, long runtime and stable performance, helping pet brands and OEM/ODM partners build more competitive smart pet products.

Application Background and Battery Requirements

Smart pet water fountains combine water circulation, filtration and monitoring electronics in a compact enclosure. The battery must deliver both stable voltage and enough capacity to support different working modes of the fountain.

Key Battery Requirements

• Stable voltage supply for pumps, sensors and control boards.
• Sufficient capacity to support continuous operation, standby and intermittent high-load working cycles.
• Compact size to fit within the fountain housing without affecting the water tank volume and appearance.
• Reliable safety performance against leakage, overheating and short-circuiting.
• Low self-discharge to maintain power during idle periods or shipment and storage.

Main Design Challenges

• Handling variable motor loads and pump start-up currents without voltage drop.
• Balancing capacity, size and cost for different product levels.
• Ensuring long-term safety in humid, water-related environments.
• Meeting international safety standards and transportation regulations for global shipping.
• Providing an easy-to-integrate battery pack solution for OEM/ODM engineers.

For pet brands and project managers, choosing the right battery partner helps reduce design risk and after-sales problems, while improving product stability and user satisfaction.
