What Makes Our Laptop Power Bank Better?

We turn customers’ ideas into perfect wireless charging power bank products.

Today’s requirements for an e-bike battery are getting more and more complex.  It is a challenge for any e-bike battery manufacturer to find the best solution for all applications. 

Our rechargeable e-bike batteries combine low weight with ergonomic design and simple handling. It’s an efficient, long-life energy source. We know how to make your e-bike battery better.

  1. Customer-oriented battery design
  2. Smart BMS and 3lvl protection
  3. Low self-discharge rate
  4. Great consistency under severe circumstances
  5. Strict validation tests with cells
  6. Automated production process
  7. Understanding of functional safety  

Compact and Safety

Magnetic ultra-thin power banks are the latest trend. Achieving such a slim design with high energy density is a big technical challenge.  Reachtek’s advanced battery control and smart design have made our ultra-thin magnetic power banks a top choice for many premium brands worldwide.

We know size and safety are key. Our expert team designs compact, lightweight power banks without compromising safety, even in the tightest spaces. Innovation meets safety in every ultra-thin magnetic power bank we create.

Intelligent BMS

Integrate with protocol applicable to the onboard applications, allowing you to communicate with the e-bike battery during riding. Battery Management System detects potential sources of error and protects cells from overloading.

  • Full solutions customized BMS
  • OTA update support
  • 3-level protection for current, voltage, temperature
  • Diagnose tool history & error table
  • Multi functions and high power in small volume
  • Protocol CAN(Adaptable from 250k to 1MB), RS485, UART

Low Power Consumption

Low self-discharge, no over-discharge, and longer cycle life are challenges to any e-bike battery manufacturer. We design our batteries in a way that they consume less energy and have low self-discharge. 

  • Cell low self-discharge
  • Pack low self-discharge
  • Low power consumption ≤ 30μA

Great consistency:

  • Deep sleep mode for storage
  • Free of charge for 3 years
  • Cell voltage difference ≤ 15mA
