Electric Cycle Kit Battery Sizing Guide: 7.8Ah, 10Ah, 13Ah & 15Ah Compared (2026)

The Heart of Your E-Bike

Choosing the right battery is crucial for your conversion kit's performance. The battery determines your range, speed, and overall bike weight.

Battery Types

Lead-Acid Batteries

Cheaper but heavy and bulky. They have a shorter lifespan (300-500 cycles) and take longer to charge. Suitable only for ultra-budget builds where weight is not a concern.

Lithium-Ion Batteries

The industry standard. Lightweight, compact, and long-lasting (800-1000+ cycles). Though initially more expensive, they offer better value over time.

Voltage and Capacity

Match the battery voltage (e.g., 36V, 48V) to your motor kit. Higher capacity (Ah) means longer range. A 36V 9 AHbattery is a common starting point for most commuters.
