48V 14Ah Li-Ion Replacement E-Bike Battery Pack (Hailong Down Tube Format for Rad Power Bikes)


Restore lost range or double your daily transit capacity with the 48V 14Ah Hailong Down Tube Lithium-Ion Replacement Battery Pack. Purpose-built for high-demand commuting and utility riding, this heavy-duty battery pack is an ideal replacement or spare for popular Rad Power Bikes (RadRunner 2, RadCity 4, RadCity Step-Thru 3, RadWagon, and RadRover 4) as well as custom Hailong down-tube conversions. Powered by Grade-A lithium cells and managed by an integrated 30A Smart BMS, this battery supports continuous power delivery for motors rated up to 1000W, keeping you moving without range anxiety.

⚠️ Fitment & Battery Discharge Pinout Guidelines

CRITICAL COMPATIBILITY CHECK BEFORE ORDERING:

  • Down Tube Casing Dimensions: Overall physical dimensions are $380 \times 95 \times 89\text{ mm}$ ($14.96" \times 3.74" \times 3.50"$). Verify frame clearance along the bottle mount braze-ons.

  • Discharge Port & Base Mount: Ships with its own matching Hailong 4-pin or 5-pin mounting base plate. While electrically compatible with 48V Rad Power systems, installing the included mounting plate guarantees a clean lock-in connection.

  • 30A Continuous Discharge BMS: Fully compatible with standard 250W, 500W, 750W, and upgraded 1000W motor controllers ($54.6\text{V}$ charge cut-off voltage).

🚀 Key High-Performance Features

  • $672\text{ Wh}$ High-Capacity Power Storage: Grade-A lithium-ion cells provide 800–1000+ full charge-discharge cycles while maintaining stable voltage under load.

  • Integrated 30A Smart BMS Defense: Multi-stage internal circuit guards against overcharging, over-discharging, thermal overloads, short-circuits, and cell imbalance.

  • Smart Charge & Capacity Meter: Features a top-mounted LED power level indicator button to check remaining battery capacity instantly before hitting the road.

  • Key-Locked Frame Security: Quick-release locking cylinder locks the battery securely to the down-tube baseplate, preventing theft while allowing easy removal for indoor charging.

  • Extreme Safety Testing: Every production batch undergoes strict crush, drop, extrusion, and puncture resistance testing to ensure total pack stability under real-world riding conditions.
