Comprehensive Comparison of 6S3P Battery Packs for UAVs: Why Lithonic INR18650 30HR Stands Out
Summary: This article evaluates three 6S3P battery configurations for UAV applications, focusing on discharge capability, weight, energy density, and practicality. The analysis highlights Lithonic INR18650 30HR as the optimal choice for high-performance drones due to its superior current handling, compact design, and energy efficiency.
Parameter | Lithonic INR18650 30HR-6S3P | Molicel INR18650 P30B-6S3P | Molicel INR21700 P42A-6S3P |
---|---|---|---|
Voltage | 22.2V | 22.2V | 22.2V |
Capacity | 9Ah | 9Ah | 13Ah |
Max Continuous Current | 210A | 108A | 135A |
Weight | ≤0.9kg | ≤0.9kg | ≤1.26kg |
Energy Density | ~222 Wh/kg | ~222 Wh/kg | ~229 Wh/kg |
IR | 2~3mΩ | 6~8mΩ | 8~10mΩ |
A. Discharge Capability
Lithonic INR18650 30HR delivers 210A continuous current, nearly double the output of Molicel P30B (108A) and 55% higher than P42A (135A). This makes it ideal for high-thrust UAV missions requiring rapid acceleration or heavy payloads17.
Validated at 60A discharge with >3000mAh capacity retention, Lithonic ensures stable voltage under extreme loads, critical for avoiding mid-flight power drops7.
B. Weight and Energy Efficiency
Despite matching Molicel P30B in weight (≤0.9kg), Lithonic offers 50% higher current output, translating to superior power density.
While Molicel P42A (13Ah) provides higher total energy (288.6Wh vs. 199.8Wh), its heavier design (1.26kg) reduces UAV agility. Lithonic balances energy-to-weight ratio for dynamic flight maneuvers69.
C. Thermal and Safety
Nickel tab welding and PVC packaging ensure structural integrity, even without a protection board. Lithonic’s low internal resistance (<3mΩ) minimizes heat generation during high-current discharge, aligning with industry benchmarks for safety79.
Unmatched Power Output: Sustains 70A per cell, enabling UAVs to handle demanding applications like aerial photography with heavy gimbals or emergency response missions7.
Compact and Lightweight: The 18650 form factor (18mm diameter) allows dense packing, optimizing space in UAV battery compartments9.
Cost-Effective Maturity: Leveraging standardized 18650 production lines, Lithonic ensures consistent quality and lower manufacturing costs compared to niche 21700 cells56.
Proven Reliability: Validated capacity retention under high discharge rates (60A) ensures long-term performance, reducing replacement frequency7.
For UAV applications prioritizing power-to-weight ratio and high-current endurance, Lithonic INR18650 30HR outperforms competitors. While Molicel P42A offers higher capacity, its weight and lower current limits hinder agility. Molicel P30B, though lightweight, lacks the discharge capacity for intensive tasks. Lithonic’s blend of 3000mAh capacity, 70A/cell output, and compact design makes it the superior choice for commercial and industrial drones.
Conclusion
Lithonic INR18650 30HR-6S3P stands out as the most versatile and high-performing battery solution for UAVs, combining cutting-edge discharge capabilities with industry-leading energy efficiency. Its adoption ensures enhanced flight performance, reliability, and cost savings, solidifying its position as the top recommendation for modern drone applications.
Important reminder: The most crucial point: The price of Lithonic INR18650 30HR is still the cheapest among the three
