All battery packs in this collection are pre-stocked in our local overseas fulfillment centers across the United States, United Kingdom, Canada, Japan, and the European Union, providing direct domestic dispatch with full tracking and rapid delivery in 3–7 business days.
⚡ Key Performance Features
- Elevated High-Voltage (LiHV) Architecture: Supports 3.8V nominal voltage and up to 4.35V per cell fully charged, delivering a higher discharge plateau, increased motor RPM, and superior top-end punch compared to standard LiPo packs.
- Colossal 8000mAh Capacity: Delivers exceptional running endurance for marathon track sessions, high-speed passes, and aggressive bashing without frequent battery swaps.
- Explosive 140C High-Rate Discharge: Provides instant, linear throttle punch and minimal voltage sag under heavy brushless motor acceleration.
- Heavy-Duty 10AWG Silicone Wire: Premium ultra-soft 10AWG high-flex silicone leads maximize high-amperage current transfer while reducing resistance and thermal buildup.
- High-Current Gold-Plated Connectors: Factory-fitted with pre-soldered, low-resistance XT90 or EC5 main connectors and universal JST-XH balance leads.
- Rugged Protective Hardcase: Heavy-duty composite shell shields internal cells against severe chassis impacts, loose gravel, rollovers, and high-speed crashes.
- Gold Series Graphene-Enhanced Cells: Advanced graphene composite cell matrix drastically minimizes internal resistance (IR), optimizes heat dissipation, and prolongs cycle lifespan.
- Flexible Multi-Pack Bundles: Available in convenient 1-Pack, 2-Pack, up to 6-Pack options to scale from casual practice to full race-day rotation.

⚠️ LiHV Care & Safety Guidelines
- Always use a certified LiHV-compatible balance charger set to LiHV balance mode (4.35V/cell cutoff).
- Never leave charging batteries unattended, and always charge inside a fireproof LiPo safety bag.
- Do not discharge below 3.2V per cell under load to prevent permanent cell damage.
- Store batteries at 3.80V–3.85V per cell in a cool, dry place when not in use for more than 48 hours.
