BECELL stocks genuine RENLIN/Reliance INR21700-RH60 21700 rechargeable cells. Ultra-low ≤7mΩ ACIR, 20A continuous discharge, -40℃ to 80℃ operation, 6000mAh capacity. Perfect for high-power applications. Available for wholesale & global shipping.

Power Meets Energy: RENLIN INR21700-RH60 – The High-Rate 21700 Cell You Need

While many 21700 cells chase higher capacity, the RENLIN (Reliance) INR21700-RH60 takes a different path: ultra-low internal resistance combined with exceptional thermal and rate capability. This is the cell for applications that demand both energy and power – without compromise.

Key Specifications at a Glance

• Nominal Capacity: 5850mAh min / 6000mAh typical (0.2C discharge)

• Nominal Voltage: 3.60V

• AC Internal Resistance (1kHz): ≤7 mΩ (ultra-low, industry-leading)

• Max Continuous Discharge Current: 20A (with 80℃ cell surface cut-off)

• Max Continuous Charge Current: 6A

• Weight: ≤71.0g (lighter than many 6000mAh cells)

• Dimensions: Max Ø21.6mm × H70.9mm

Wide Operating Temperature Range

The RH60 excels in harsh environments:

• Charge: -10℃ to 45℃ (recommended recovery <45℃)

• Discharge (ambient): -40℃ to 60℃

• Discharge (cell surface): -40℃ to 80℃ – perfect for high-power discharge in summer or enclosed spaces.

Rate Discharge Performance (25℃, 0.5C charge, discharge to 2.5V or 80℃ cut-off):

Even at 20A continuous, the RH60 retains 90% of its low-rate capacity – a testament to its low impedance design.

Low-Temperature Discharge (1.2A, cut-off adjusted per temp):

 

The RH60 starts and delivers meaningful power even at -40℃ – ideal for cold-climate EVs, outdoor power tools, and military applications.

Cycle Life

• 500 cycles under 6A charge / 12A discharge (4.2V–2.5V) at room temperature, retaining ≥80% of initial capacity (estimated, based on typical Li-ion NMC performance).

Safety & Certifications

The RH60 has passed rigorous safety tests per IEC62133 and UL1642 standards:

• 2C 6V overcharge – no fire, no explosion

• Forced discharge (6A for 90min) – no fire, no explosion

• External short circuit (80±20mΩ wire) – no fire, no explosion

• Hot box (130℃ for 10min) – no fire, no explosion

• Crush (13kN) – no fire, no explosion

• Vibration (UN38.3) – no leakage, <10% OCV drop

Compare RH60 with Other High-Capacity 21700 Cells

Key takeaway: The 21700 RH60 is not the highest capacity cell, but it offers 3x lower internal resistance and ~60% higher continuous discharge current than conventional 6000mAh cells. This translates into less heat generation, higher peak power, and better cycle life under demanding loads.

Applications Best Suited for  RELINCE RH60

• High-power cordless power tools (drills, saws, grinders) – 20A sustained discharge supports heavy loads.

• FPV racing drones – low IR means instant throttle response and less voltage sag.

• Electric motorcycles and scooters – parallel strings of RH60 deliver impressive acceleration.

• Portable jump starters – high burst current capability.

• Energy storage systems (ESS) with frequent high C-rate charge/discharge.

• Medical devices (defibrillators, surgical tools) requiring reliability and power.
