Compatible e-bike replacement batteries, also known as aftermarket batteries, are premium energy storage units designed to seamlessly replace original equipment manufacturer (OEM) battery packs. Engineered by professional lithium battery manufacturers in China, these batteries provide a perfect fit for globally recognized motor systems without the premium price tag. They feature high-quality lithium-ion cells and intelligent Battery Management Systems (BMS) to ensure full communication with the e-bike's controller and display, delivering equal or superior range and performance.
True Plug-and-Play Compatibility
Our replacement batteries are meticulously engineered to match the exact physical dimensions and communication protocols of original drive systems. This ensures zero error codes and a hassle-free installation process for your end-users or repair shop clients.
Premium Grade-A Cells
To guarantee long-lasting performance, we strictly assemble our compatible packs using top-tier cells from industry leaders like Samsung, LG, and Panasonic. This results in higher energy density, lower internal resistance, and a longer lifecycle compared to standard aftermarket options.
Upgraded Capacity Options
We offer expanded capacity configurations (higher Amp-hours) within the same original casing size. This allows riders to significantly upgrade their e-bike's mileage per charge without needing to modify their bicycle frame.
Cost-Effective Wholesale Solutions
By sourcing directly from our advanced manufacturing facility in China, distributors and retailers can offer high-quality replacement solutions to their market at a highly competitive price point, maximizing profit margins while solving customer pain points.
The Value of Aftermarket Batteries for B2B Distributors
● Supplying reliable replacement batteries allows e-bike dealers and repair centers to offer a highly sought-after service, capturing the massive aftermarket demand as older e-bike batteries naturally degrade.
● Offering fully compatible packs means your clients don't have to wait for expensive, backordered OEM parts, ensuring quick turnaround times for e-bike refurbishments and repairs.

Integrated (In-Tube) Batteries
Designed to fit seamlessly inside the bicycle's downtube (similar to Bosch Powertube designs). These provide a sleek, aerodynamic look and protect the battery from weather elements and physical impact. Our compatible in-tube batteries maintain the exact dimensions for a perfect fit.
Downtube (Frame-Mounted) Batteries
Often referred to as Hailong, Shark, or Powerpack styles. These sit on top of the downtube and are secured by a locking mount. They are extremely popular due to their easy removal and high capacity potential.
Rear Rack Batteries
Mounted on the luggage carrier above the rear wheel. This style is frequently used on city e-bikes, step-through frames, and cargo bikes. Our replacement rack batteries come with integrated taillight compatibility and exact mounting rails.
Folding Bike & Silver Fish Batteries
Compact battery packs designed to fit behind the seat post or within the frames of folding e-bikes. We manufacture highly durable replacements that ensure standard commuters can keep their older folding e-bikes running for years.
Selecting the correct aftermarket battery requires verifying a few critical specifications. First, the voltage must strictly match the original system (e.g., a 36V motor requires a 36V replacement battery). Using a higher voltage battery on an incompatible controller can cause permanent damage.
Second, compare the physical shape and the discharge connector type. Our compatible series are molded 1:1 against the original brands to guarantee the locking mechanisms and connector pins align perfectly.
Finally, you can choose a higher Amp-hour (Ah) capacity than the original. For example, replacing a 400Wh OEM battery with our compatible 500Wh or 625Wh pack will directly increase the riding range without affecting motor safety.
Manufacturing Quality of Our Compatible Batteries
Smart Battery Management System (BMS)
The core of a successful compatible battery is its BMS. Our proprietary smart boards perfectly replicate the CAN bus or UART communication protocols of major brands. This ensures the e-bike display accurately shows battery percentage and prevents any system lockouts or error codes.
Robust Outer Housing
Our battery casings are constructed from impact-resistant, fire-retardant ABS/PC materials. They undergo rigorous drop testing and are sealed to achieve high waterproof ratings (IP65/IP67), protecting the internal cells from harsh outdoor environments.
Precision Spot Welding
We utilize automated pure nickel strip spot welding processes. This minimizes internal resistance, prevents heat buildup during high-current discharging, and ensures the structural integrity of the cell pack even on bumpy mountain trails.
Comprehensive Safety Protections
Every replacement battery we produce features multi-level protection against overcharging, over-discharging, short circuits, and thermal runaway, guaranteeing end-user safety.
Custom OEM/ODM Services
As a leading factory, we don't just supply off-the-shelf replacements. We offer full OEM services, allowing B2B clients to customize cell brands, BMS parameters, and add their own company logos to the battery casings for brand building.
Maintain a Partial Charge for Storage.
If dealers are stocking replacement batteries for extended periods, or users are winterizing their e-bikes, never store the battery empty or at 100%. The optimal storage charge level for lithium-ion packs is around 50% to 60%.
Avoid Extreme Warehouse Temperatures.
For B2B distributors, ensure your warehouse is climate-controlled. High temperatures accelerate cell degradation, while freezing temperatures can cause irreversible damage. The ideal storage temperature is between 10ºC and 20ºC.
Regular Maintenance Recharging.
Even when not in use, the smart BMS consumes a tiny amount of power. It is highly recommended to check the inventory and give the replacement batteries a short maintenance charge every 3 to 4 months to prevent deep discharge.

Global Supply Chain Expertise
With years of experience in the foreign trade battery industry, we understand the complexities of shipping dangerous goods (DG). We provide comprehensive logistics solutions, ensuring your wholesale orders arrive safely and legally via sea or air freight.
Rigorous Quality Certification
All our compatible e-bike batteries undergo strict quality control and hold essential international certifications, including CE, RoHS, UN38.3, and MSDS, allowing for smooth customs clearance and compliant local distribution.
Reliable Warranty & Support
We stand behind our manufacturing quality. We offer comprehensive warranty terms for our B2B partners, backed by responsive technical support to assist with any compatibility inquiries or after-sales service needs.
