Frog Battery Pack for Electric Bicycles
The "Frog" battery is a classic and versatile power source for e-bikes, particularly popular for its unique design and compatibility with a wide range of bicycle frames. Named for its shape and mounting style, which often sees it suspended behind the seat post, it provides a well-balanced and discreet power solution for many conversion kits and factory-built e-bikes.


Key Specifications & Voltage Options:
24V (9Ah): A lightweight and compact option ideal for entry-level e-bikes and low-wattage motors (250W-350W). A 24V 9Ah battery provides a reliable range for shorter commutes and leisure rides, offering a great balance between performance and portability.

36V: The industry standard for a wide variety of e-bikes. A 36V Frog battery is compatible with motors up to 500W and provides an excellent balance of speed and range for everyday riding.

48V: A high-performance option for riders who need more power and speed. A 48V Frog battery is well-suited for motors from 500W to 750W, providing faster acceleration and better hill-climbing ability.

Features and Design:
Seat Post Mounting: The defining feature of the Frog battery is its "drawer" format and mounting style. The base plate securely attaches to the bike's seat post tube, allowing the battery to slide on and lock into place. This keeps the battery out of the way and maintains a clean frame appearance.

Removable & Lockable: The battery is designed for convenience. It can be easily removed from the bike with a key-lock mechanism, which serves as a basic anti-theft deterrent. This allows you to charge the battery indoors, swap it with a spare, or store it securely when not in use.

High-Quality Cells: The best Frog batteries are built with genuine, A-grade lithium-ion cells from trusted manufacturers like Samsung, LG, or Panasonic. These cells ensure a long cycle life, stable performance, and high energy density for a better range.

Integrated Safety: A built-in Battery Management System (BMS) is a crucial component that protects the battery and the e-bike system. The BMS safeguards against over-charging, over-discharging, over-current, and short circuits, ensuring a long and safe lifespan.


Durable Casing: The battery is housed in a hard, durable ABS plastic or aluminum alloy case that protects the internal cells from physical shocks and the elements.

Versatility and Compatibility:
The universal nature of the Frog battery's mounting system makes it compatible with a wide variety of bike frames and conversion kits. It is a common power source for folding bikes and city bikes and can be used with a range of motors, including Bafang and Tongsheng.
