Introduction

The global demand for automatic self-cleaning litter boxes is rising rapidly as pet owners seek cleaner, safer, and more convenient solutions for indoor cat care. With stronger motors, odor-control systems, sensors, and smart IoT connectivity, today’s litter robots are no longer simple mechanical devices—they are intelligent appliances that require stable and safe power systems.

Behind every smooth drum rotation, every detection cycle, and every self-cleaning action lies one core component: the battery pack. For OEM/ODM manufacturers, the battery system directly determines performance, safety, user experience, and long-term reliability. As the market evolves, high-quality, custom-designed NMC/LFP battery packs have become essential.

1. Why the Battery Is the Core System Behind Modern Automatic Litter Boxes

Automatic litter boxes are motor-driven smart machines operating in confined spaces and sensitive environments. The battery pack has a direct impact on:

• Motor performance & torque output – determines whether rotation is smooth and powerful.
• Safety during power outages – guarantees safe operation even when AC power is lost.
• Sensor accuracy – stable voltage helps ensure reliable detection of cats and waste levels.
• Hygiene & odor-control reliability – uninterrupted operation keeps the environment clean.
• User convenience – less downtime and fewer manual interventions.

In short: an automatic litter box is only as safe and functional as its battery pack.

2. Typical Battery Requirements for Automatic Cat Litter Robots

2.1 Preferred Cell Chemistry: NMC vs. LFP

• NMC (Nickel Manganese Cobalt) – high energy density, compact size, and good high-rate discharge performance.
• LFP (Lithium Iron Phosphate) – long cycle life, excellent thermal stability, and very high safety, especially under continuous load.

2.2 Typical Pack Configurations

• 3S / 4S / 6S pack architectures
• 18650 or 21700 cylindrical cells
• Capacity range from 2600 mAh to 10000 mAh or beyond

2.3 Discharge Requirements

• Continuous current: 5–15 A
• Peak current: 20–35 A for motor start and reversing
• Low internal resistance to prevent voltage sag or MCU resets

2.4 Temperature Requirements

• Enclosed housing with limited ventilation demands high thermal stability.
• LFP chemistry is often preferred when maximum heat tolerance and safety margins are required.

2.5 BMS Requirements

• Protection features: SCP, OCP, OVP, UVP
• MOS redundancy for safer fault handling
• NTC temperature monitoring
• UART / I2C communication options
• Low standby consumption to maintain long-term readiness

3. Pain Points Faced by Litter Box Manufacturers

Based on global ODM/OEM projects, we frequently see recurring challenges:

• Motor stalls caused by insufficient peak current capability.
• Voltage sag leading to MCU resets or incomplete cleaning cycles.
• Thermal buildup inside confined housings.
• Backup power failure during AC outages.
• Short cycle life under daily or multi-daily operation.
• Inconsistent cell supplier quality affecting reliability.

These problems increase warranty costs, create safety risks, and damage long-term brand reputation.
