The Complete Guide to E-Bike Batteries: The Power Behind Every Ride
Understanding your battery is the first step to building a great e-bike.
The battery is the heart of your electric bike — it determines the bike’s power, range, and safety.
A standard e-bike battery consists of four key components:
1. Battery Cells
Common models: 18650, 21700, 32700
Leading brands: Samsung, Panasonic, LG, Lishen, and others
Each cell provides 3.6–3.7 V; multiple cells are connected in series/parallel to form the full pack
2.BMS (Battery Management System)
Controls charging and discharging
Protects against over-charge, over-discharge, and short circuits
Monitors temperature, voltage, and capacity to extend battery life
3. Battery Case
Common types: Hailong, Silverfish, Dolphin, and Custom Box
Provides physical protection, waterproofing, and vibration resistance
Also serves as a design element for your brand
4.Connectors & Wiring
Typical types: XT60, Anderson, DC plug
Quality connectors ensure stable current delivery and safety
Know your numbers — match the battery to your customers’ needs.
| Voltage (V) | Typical Capacity (Ah) | Bike Type | Key Features |
|---|---|---|---|
| 36V | 10Ah–20Ah | City / Commuter | Efficient, ideal for short trips |
| 48V | 13Ah–30Ah | Mountain / Urban | Balanced power and range |
| 52V | 15Ah–25Ah | Modified bikes | Stronger acceleration, sporty feel |
| 72V | 20Ah–40Ah | Delivery / Cargo | Extreme power and long range |
Pro Tip:
Voltage = speed.
Capacity = range.
Cell quality = lifespan.
| Comparison | Lithium Battery | Lead-Acid Battery |
|---|---|---|
| Weight | Light (⅓ of lead-acid) | Heavy |
| Lifespan | 800–1000 cycles | 300–500 cycles |
| Cost | Higher | Lower |
| Energy Density | High | Low |
| Eco-friendliness | Recyclable, clean | Contains lead, polluting |
| Ideal For | Premium or performance bikes | Entry-level short-range bikes |
Marketing Line:
“Lighter. Further. Safer. — That’s the power of lithium.”
Proper use = longer life + greater safety
1.Avoid charging in extreme temperatures (below 0 °C / above 45 °C)
2.Always use the original charger
3.Recharge every 3 months during long storage
4.Keep terminals dry and clean
5.Stop using the battery immediately if it swells, smells, or overheats
Visual Tip:
Use simple icons (temperature, plug, raindrop, power bar) to display each tip clearly.
Solid-State Batteries
Higher energy density & safety
No liquid electrolyte → lower fire risk
Expected to enter the e-bike market soon
Swappable Batteries
Popular in delivery and sharing fleets
Riders can exchange empty packs for charged ones in seconds
Great opportunity for dealers & service centers to join new networks
Marketing Line:
“We don’t just sell batteries — we power the future of e-mobility.”
A battery is not just a component — it’s the core of every ride experience.
By choosing premium cells, a reliable BMS, and durable housing,
you give your customers longer range, better safety, and lasting confidence in your brand.
