E-Bike Battery Solutions
Matched cells and proven packs for 36V/48V/52V e-bike systems.
Industry Overview
The global e-bike market is projected to exceed 40 million units annually by 2027, with Europe as the largest market. E-bike battery systems range from 250Wh commuter packs to 750Wh+ cargo and mountain bike configurations. The key challenge for e-bike brands: balancing range, weight, cost, and certification compliance — without investing 6-12 months in custom pack development.
Battery Requirements — What E-Bikes Demand
- Energy density — range is the #1 customer metric. Every extra Wh matters.
- Moderate continuous discharge — typical 250W-750W motors draw 7-15A at 36V/48V, well within 2-3C for most pack configurations.
- Cycle life — 500+ cycles minimum for consumer confidence and warranty support.
- Vibration resistance — cells and welds must survive years of road vibration.
- Regulatory compliance — EN 15194 (EU), UL 2849 (US), UN38.3 for transport.
Recommended Cells
| Cell | Best For | Key Spec |
|---|---|---|
| INR18650-2600mAh-3C | Standard commuter packs (400-500Wh) | Cost-effective, proven reliability |
| INR18650-3350mAh-3C | Long-range packs (600-700Wh in 10S5P) | Highest 18650 energy density |
| INR21700-5000mAh-3C | Max-range packs (700Wh+ with fewer cells) | Best-in-class Wh per cell |
| INR21700-4000mAh-7C | High-torque cargo/mountain e-bikes | Capacity + power balance |

- CE marking
Case Example
EU commuter e-bike brand — needed 48V 13S4P 672Wh pack. Custom development quote: 8 months, €45,000 certification. We matched a proven Sunwoda pack from their existing library: identical specs, already EN 15194 certified. Delivered samples in 3 weeks. Project to production: 3 months total.
FAQ
Can you provide packs with custom enclosures?
Yes — we can match packs that fit common downtube and rear-rack form factors. Custom mechanical integration support available.
What brands of BMS do you use?
Matched packs come with Tier-1 BMS from Texas Instruments, Maxim, or Renesas-based designs, configured for your voltage and current requirements.
