As China’s New National Standard for electric bicycles is fully implemented in 2025, the industry faces unprecedented challenges.
• ⚖️ Total vehicle weight limited to 55 kg
• 🧩 Plastic components reduced to only 3 kg
• 🔥 Much stricter requirements for battery fire resistance, impact resistance, and waterproofing
To meet — and exceed — these standards, DFD proudly introduces its 48V 24Ah New National Standard Battery Pack, an all-in-one solution designed for next-generation compliant e-bikes.
🔐 Breakthrough #1: Dual Explosion-Proof Valves + Dedicated Venting Channels
Zero thermal runaway. Zero fire risk.
Powered by DFD Core battery technology, the pack features:
• Dual explosion-proof valves
• Module-level directional smoke exhaust channels
Even under extreme conditions such as short circuits or overheating, pressure is released safely and precisely.
Even simultaneous risk events in dual cells result in zero combustion, fully meeting the latest fire-safety regulations.
🛡️ Breakthrough #2: Metal Enclosure + 3D Secure Mounting
Shock-proof. Drop-resistant. Built to last.
A reinforced 3D fixation structure between modules and enclosure has passed:
• Multi-scenario vibration tests
• Drop and impact tests
Whether on rough roads or during accidental collisions, the battery remains stable — eliminating safety risks at the structural level.
🌧️ Breakthrough #3: IP67 Dual-Seal Waterproof Design
Ride confidently in rain or flooded conditions.
Using a dual sealing process (compression-molded sealing ring + sealant), the pack:
• Blocks moisture intrusion
• Prevents short-circuit failures
• Performs reliably in heavy rain, water splashes, or vehicle washing
Perfect for humid and all-weather riding environments.
⚡ Breakthrough #4: LFP Chemistry + Cost Optimization
By adopting Lithium Iron Phosphate (LFP) instead of traditional ternary batteries, DFD delivers:
• Higher thermal stability
• Longer cycle life
• Environmentally friendly materials
• Lower long-term operating costs
Ideal for daily commuting and high-frequency short-distance use.
✅ Tested Beyond Standards,The battery pack has successfully passed:
The battery pack has successfully passed:
• Extreme abuse and coupled multi-scenario simulations
• Dual-battery simultaneous risk triggering
• Needle penetration, extrusion, and drop tests
Result: Zero combustion. Zero failure.
🚀 The Ideal Power Solution for New National Standard E-Bikes
No fear of bumps.
No worries about rain.
No compromise on safety.
DFD empowers compliant mobility with technology — delivering peace of mind for every ride.
