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
- True 4S HV 15.2V High-Voltage Output: Advanced LiHV chemistry charges to 4.35V per cell, maintaining a significantly higher discharge plateau for explosive acceleration and higher top-end speed.
- Blistering 140C Discharge Output: Delivers instantaneous throttle response and massive continuous current delivery with virtually zero voltage sag under demanding brushless amp draws.
- Gold Series Nano-Graphene Architecture: Premium graphene composite matrix dramatically minimizes internal resistance (IR), optimizes heat dissipation, and prolongs cycle lifespan.
- High-Capacity 6500mAh Runtime: Provides generous running endurance for extended track sessions and aggressive bashing runs.
- Heavy-Duty 10AWG Silicone Wire: Ultra-thick 10AWG high-flex silicone leads maximize high-amperage current transfer while reducing resistance and thermal buildup.
- High-Current Connector Options: Factory fitted with genuine gold-plated EC5 or XT90 power connectors alongside standardized JST-XH balance leads.
- Rugged Protective Hardcase: Heavy-duty composite shell shields internal cells against severe chassis impacts, loose gravel, rollovers, and hard landings.
- Premium Grade-A Matched Cells: Strict cell sorting guarantees consistent internal resistance, uniform per-cell voltage, and dependable cycle longevity.

⚠️ LiHV Care & Safety Guidelines
- Always use a certified LiHV-compatible balance charger set to 4S 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.
