Ultra-Thin lithium battery solution for smart jump ropes and fitness exercise equipment

To assist with product selection and performance comparison, this guide summarizes key specifications of widely used rechargeable lithium batteries in the current market, categorized by application type: smart fitness equipment batteries, cylindrical general-purpose batteries, and compact device batteries.

1. Lithium Batteries for Smart Fitness Equipment

These batteries are specifically designed for low-power, portable wearable devices. They offer compact size, stable discharge performance, and extended standby times.

2. Cylindrical General-Purpose Lithium Batteries

Ideal for power tools, energy storage systems, and portable power banks, these batteries are known for high capacity, strong discharge performance, and standardized dimensions for easy integration.

1. 18650 Lithium Battery

• Nominal Voltage: 3.6V
• Capacity Range: 2000–3400mAh
• Max Charging Voltage: 4.2V ± 0.05V
• Cut-off Discharge Voltage: 2.75V
• Size: Ø18mm × 65mm

2. 26650 Lithium Battery

• Nominal Voltage: 3.7V
• Capacity Range: 3000–5000mAh
• Max Charging Voltage: 4.2V
• Cut-off Discharge Voltage: 2.5V
• Size: Ø26mm × 65mm

3. Lithium Batteries for Compact Devices

Designed for space-constrained and ultra-low power devices, such as smart toys, pet gadgets, and mini sensors.
