Why Do Cat Toys Prefer Small LiPo Batteries? – A Complete Guide to Custom Batteries for Pet Toys
In today’s smart pet toys, such as electric flapping fish, automatic laser pointers, and rolling mouse toys, small lithium polymer (LiPo) batteries have become the standard power source, replacing traditional disposable batteries (e.g., AA/AAA). Why is this shift happening? This article explores the advantages of LiPo batteries in pet toys and how companies like Himax, a leading manufacturer of compact, high-performance LiPo batteries, are driving innovation in this space.
Why Are LiPo Batteries the Best Choice for Pet Toys?
-
Compact and Lightweight for Dynamic Movement
LiPo batteries use flexible pouch packaging, allowing ultra-thin and custom shapes (e.g., long strips, small blocks) to fit tight spaces.
Disposable batteries (AA/AAA) are bulky and heavy, reducing the toy’s agility (e.g., affecting a cat fish’s natural swaying motion).
Example: A 220mAh LiPo (3.7V) weighs just ~5g, while two AAA batteries (3V) weigh ~24g, significantly impacting toy performance.
-
Rechargeable for Long-Term Cost Savings
LiPo batteries can be recharged 300–500 times, reducing replacement hassle and costs.
Disposable batteries require frequent changes, leading to higher long-term expenses.
Cost Comparison:
| Battery Type | Capacity | Cycle Life | Unit Cost | Annual Cost (Daily Use) |
| LiPo | 220mAh 3.7V | 500 cycles | $0.7–1.5 | ~$1/year |
| AAA Alkaline | 1.5V×2 | Single-use | $0.3–0.5 each | $30+/year
|
-
Stable Discharge for Consistent Performance
LiPo provides a steady voltage (3.7V–3.0V), ensuring smooth motor operation.
Alkaline batteries gradually drop voltage (1.5V→0.9V), causing weaker performance over time.
-
Eco-Friendly, Reducing Battery Waste
LiPo is reusable, minimizing e-waste.
Alkaline batteries contain heavy metals (zinc, manganese), posing environmental risks.

Key Specifications to Consider
| Parameter | Typical Value | Selection Guide |
| Voltage | 3.7V (1-cell) | Ideal for low-power motors & USB charging |
| Capacity | 100mAh–500mAh | Based on runtime needs (e.g., 220mAh ≈ 1 hour) |
| Size | Custom (e.g., 20×30×3mm) | Must fit toy’s internal space |
| Charging | Micro USB / Wireless / Contact Pads | Depends on toy design
|
| Discharge Rate (C-rating) | 1C–3C 1C for standard toys; | 3C for high-power motors |
