36V Lithium Replacement Battery With Full BMS For Portable Folding E-Bikes

Our 36V lithium battery packs are compatible with most folding electric bikes, ideal for daily commuting and short outdoor trips. Its small size saves storage space after you fold up the vehicle.

We keep three standard capacity options in stock for bulk orders: 10.4Ah, 11.6Ah, 14Ah. If you require longer travel distance, we can customize batteries with larger capacities to meet your requirements.

Every battery uses qualified lithium cells and comes with a complete BMS protection board. It can output steady power during riding and features plenty of charge cycles for long-term daily use. The compact size fits the installation space of most folding bikes without modification.

We provide bulk supply for e-bike factories, overseas importers and local distributors. OEM adjustments on capacity, connectors and shell appearance are supported for long-term cooperative orders.

Main Advantages of the 36V Folding Electric Bike Battery

 

1. Compact Design for Folding Frames

Folding e‑bikes demand a slim and space‑efficient battery. This 36V pack is engineered for:

  • Compact dimensions that fit downtube, rear rack, or frame‑integrated layouts
  • Low weight, making the bike easier to fold, carry, and store
  • Stable mounting and wiring to reduce vibration and prevent power interruption

Ideal for city riders who frequently fold and move their bikes on public transport or into small living spaces.

 

2. Multiple Capacities for Different Riding Needs

Choose from three standard capacities depending on how far and how often you ride:

  • 36V 10.4Ah – Lightweight Everyday Option

Suitable for short to medium daily commutes

Prioritizes portability and easy handling

Good for riders who charge frequently and ride mostly on flat city roads

  • 36V 11.6Ah – Extra Range for Frequent Users

Offers more range than the 10.4Ah while keeping weight manageable

Great for regular commuters and active riders

A smart choice for users who want a balance between run time and size

  • 36V 14Ah – Long‑Range Capacity

Designed for riders who need extended distance per charge

Suitable for longer commutes, delivery work, or touring

Reduces charging frequency during the day, improving convenience

 

Custom High‑Capacity Solutions

For users with demanding requirements, we can build custom 36V batteries with higher Ah ratings, ideal for:

  • Delivery and logistics fleets
  • Bike‑sharing and rental companies
  • Riders in hilly cities or carrying heavy loads

Share your target range or working hours, and we can propose a tailored capacity and configuration.

 

  • 3. Premium Lithium‑Ion Cells

The battery uses high‑grade lithium‑ion cells to ensure:

  • Smooth and consistent power delivery for pedal assist or throttle
  • High energy density, allowing more capacity in a compact housing
  • Long service life when used with proper charging habits
  • Reduced voltage drop under acceleration or climbing

This cell choice improves overall riding comfort and reduces performance loss as the battery discharges.

 

  • 4. Intelligent Battery Management System (BMS)

An integrated smart BMS protects the battery and your e‑bike components by offering:

Over‑charge and over‑discharge protection

Over‑current and short‑circuit protection

Temperature protection and monitoring

Active cell balancing to keep each cell within a safe range

The BMS helps extend the battery's lifespan and provides more stable performance over hundreds of charge cycles.

 

  • 5. Easy to Carry, Easy to Charge

For folding bike owners, convenience is crucial. This 36V battery is designed to be:

  • Quick to remove and install, supporting daily take‑off charging
  • Comfortable to carry thanks to its compact shape and low weight
  • Suitable for users who store the bike in a garage but charge indoors

If you regularly transport your bike in a car, office, or on public transit, a portable battery makes your routine simpler.

 

6. Broad Compatibility with 36V E‑Bike Systems

This battery is suitable for most 36V folding e‑bikes, including:

  • 36V front or rear hub motor systems
  • Many 36V mid‑drive setups (depending on shape and connector)
  • Controllers matched to 36V nominal voltage
  • Connector and harness options can be customized to match your existing system. Provide details about:
  • Motor power (e.g., 250W, 350W, 500W)
  • Controller current and voltage
  • Current battery dimensions and plug type

We can help you confirm whether this 36V pack is compatible with your folding e‑bike.

Customization and OEM / ODM Services

 

Beyond standard 10.4Ah, 11.6Ah, and 14Ah versions, we support:

  • Custom capacity (Ah) while keeping 36V nominal voltage
  • Tailored dimensions and mounting solutions for unique folding frames
  • Customized connectors, cables, and harnesses
  • Branding options, such as logos and private‑label packaging
  • This makes our 36V folding electric bike battery an excellent choice for brands, distributors, manufacturers, and e‑mobility projects.

 

How to Choose the Right Capacity

 

When deciding between 10.4Ah, 11.6Ah, 14Ah, or a custom higher capacity, consider:

  • Average daily distance and whether you have access to charging mid‑day
  • Riding mode: low assist vs. high assist or throttle‑only
  • Road conditions: mainly flat roads or frequent hills and headwinds
  • Payload: rider weight plus cargo, child seats, or equipment
  • Budget and weight preference: higher capacity means more range but also higher cost and slightly more weight

If you share your typical route, terrain, and riding habits, we can suggest the most suitable 36V folding e‑bike battery configuration.
