✅ Why Choose This Battery?

1. Powerful & Long-Lasting Range
With a generous 70Ah capacity, this battery provides an extended cruising range, reducing charging frequency and allowing you to cover longer distances on a single charge – perfect for both urban commuting and off-road touring.

2. High-Discharge Performance for Modified Ebikes
Supporting up to 120A continuous discharge current, this battery is purpose-built for modified electric bikes equipped with 2000W or 3000W motors. It delivers instant throttle response and sustained power output even under heavy load or steep climbing conditions.

3. Smart Bluetooth BMS – Real-Time Monitoring
The built-in Bluetooth Battery Management System (BMS) allows you to monitor voltage, current, temperature, and remaining capacity in real time via a smartphone APP. Advanced protections include overcharge, over-discharge, over-current, short-circuit, and temperature safeguards for complete peace of mind.

4. Fully Customizable to Your Vehicle
Whether you need a specific case size, stainless steel or black iron box, custom charge/discharge ports, or even a custom color, we can tailor the battery to fit your modified U2 frame perfectly. No compromises on installation – we make it fit.

5. Premium Aluminum-Shell Large-Format Cells
Using high-quality prismatic aluminum-shell cells, this battery offers superior thermal management, consistent discharge voltage, and extended cycle life (≥1500 cycles) compared to standard cylindrical cells.

6. All-Weather Durability
Built with robust casing options and optional low-temperature electrolyte formulas, this battery performs reliably even in harsh outdoor conditions, including cold weather environments (down to -20°C with optional heating function).
