⚡ Key Performance Features
- Colossal 9200mAh Extreme Capacity: Sets a new benchmark for running endurance, delivering marathon track sessions, all-day bashing, and relentless speed runs without mid-session power depletion.
- High-Voltage (LiHV) Operating Chemistry: Operates at 3.8V nominal voltage and charges up to 4.35V per cell, providing an elevated discharge curve and significantly higher motor RPM throughout the entire run.
- Explosive 140C High-Rate Discharge: Delivers instantaneous throttle response, fierce straightaway acceleration, and exceptional voltage retention under punishing brushless ESC draws.
- 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: Pre-soldered with genuine low-resistance XT90 or EC5 main power plugs and standard JST-XH balance leads.
- Rugged Protective Hardcase: Reinforced composite casing shields internal high-capacity cells against harsh chassis impacts, rollovers, debris, and extreme driving conditions.
- Gold Series Graphene Cell Stacking: Premium Grade-A graphene formulation minimizes internal resistance (IR), optimizes heat dissipation, and ensures long cycle reliability.
- Flexible Multi-Pack Bundles: Available in convenient 1-Pack, 2-Pack, up to 6-Pack options to build the ultimate race-day power reserve.

⚠️ 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.
