8000mAh 50C Hard Case RC Lipo Battery | 3S/4S/6S Optional for RC Cars, Drones & Boats, Compatible with MJX 10303/7303 DC2

Core Product Highlights

• Large 8000mAh True Capacity for Ultra-long Runtime
  Genuine full-capacity cells extend single-use time greatly. Fewer battery replacements for long-time racing, crawling and flight tasks.
• 50C High Discharge Rate for Powerful Burst Output
  Premium lipo cells deliver stable high-current output with instant throttle response. No voltage drop under heavy aggressive loads for consistent power performance.
• Hard Shell Structure for Enhanced Impact Resistance
  Rigid outer casing protects the battery from squeeze and collision damage. Ideal for off-road rough use with longer service life.
• Multiple Voltage Options for Wide Compatibility
  3S/4S/6S versions available to fit RC off-road trucks, crawlers, drones and RC boats. Perfect match for mainstream models including MJX 10303 & 7303.
• Full Automatic Production & Multi-stage Quality Inspection
  Standardized full production workflow with strict multi-point testing. Highly consistent cells prevent swelling and leakage for reliable charge & discharge performance.

Detailed Product Advantages

• Precision Automated Production & Strict Cell Screening
  Complete standardized manufacturing process includes electrode batching, coating, calendering, slitting, die-cutting, lamination, welding, sealing, liquid injection, formation, aging and final inspection. K-value testing and long-time static screening ensure ultra-consistent cells with minimal voltage difference under high loads.
• High-performance Lipo Cells with Stable Power Output
  Special power-grade lipo cells support continuous 50C high-rate discharge. Low power attenuation under heavy loads for steady performance during high-speed racing, steep crawling and drone high-thrust flight.
• Hard Shell Construction for Harsh Outdoor Use
  Thickened rigid casing guards against compression, crash impact and sand abrasion. Much stronger durability than soft-pack batteries for frequent heavy-duty use.
• Broad Compatibility with Mainstream RC Devices
  Works perfectly with MJX 10303, 7303 RC buggies, as well as various drones and RC boats. Plug-and-play installation with no extra modification needed.
• Factory Direct Supply & Complete After-sales System
  Original factory direct sales guarantee authentic quality. Supported with 7-day free return & exchange plus 3-month warranty. SF Express shipping with free return shipping and dedicated customer service.

Important User Instructions

• Fully charge the battery before first use. Full voltage per single cell is 4.35V. Never overcharge. Only use dedicated chargers with overcharge protection. Do not charge unattended.
  Stop discharge immediately when single cell voltage drops near 3.6V. Voltage below 3.5V will cause permanent over-damage to cells.
• Storage rules: Maintain single cell voltage at 3.80V~3.85V if idle for over 72 hours. Perform a small-current charge-discharge cycle monthly for storage longer than 1 month.
• This battery is NOT waterproof. Keep away from liquids and humid environments to avoid internal short circuit.
• Do not touch leaked electrolyte. Rinse exposed skin or eyes with plenty of clean water and seek immediate medical help if contacted by battery fluid.
• Keep battery away from open fire and high-temperature heat sources.
• Store the battery out of reach of children and pets.
• Never disassemble or modify the battery privately. Improper disassembly may lead to short circuit and fire hazards.
• After vehicle crash or drone crash, take out the battery and inspect for overheating, leakage, abnormal smell, damaged wires and abnormal voltage. Do not reuse until fully confirmed safe.

After-sales Service Policy
