Pro 48V 14.7Ah E-Bike Battery 368mm L x 96mm W x 103mm H

UL Certified Safety | Genuine Samsung Cells | Pure Performance 

🛡️ Certified UL Safety Standards: Officially certified with strict UL warning and safety labels. Zero fire hazards, zero explosion risks. Built for maximum peace of mind and 100% compliant with US regulations. 

🔋 100% Genuine Samsung Cells: Powered by premium Samsung 21700-50GB cells. Stable, non-fading voltage for a 5+ year lifespan—no cheap generic cells. 

🎯 True 14.7Ah Capacity (No Fake Specs): 705.6Wh of pure, rigorously tested energy. Zero range anxiety, what you see is the exact massive mileage you get. 

⚡ Rock-Solid 25A Continuous Output: Delivers smooth acceleration and steady torque up to 45A peak. Perfectly optimized to unlock full power for 750W–1000W+ motor mods. 

 🎁 FREE GIFT: We include an upgraded, safer charger with a 3-pin connector with every battery!

Don't just look for a 'plug-and-play' battery for your old Rad. Those legacy base mounts from pre-2021 are prone to terminal melting under high discharge. For true safety, you need a UL-certified battery system. Our solution includes a certified high-current base mount that replaces your aged connector. It’s not just a battery swap; it’s a professional safety upgrade for your e-bike.
