The Reliance INR21700-RS60 is a high-energy, high-power 21700 rechargeable lithium-ion cell combining a minimum 5850mAh capacity with up to 50A continuous discharge. It also supports 12A fast charging under controlled temperature conditions, making it suitable for professionally engineered battery packs that need longer runtime, rapid power delivery and compact cylindrical construction.
The RS60 provides a minimum standard discharge capacity of 5850mAh when tested at 1.2A and 25±3°C. Combined with its 3.6V nominal voltage, this represents approximately 21.06Wh of calculated energy based on minimum capacity, offering substantial runtime for a single 21700 cylindrical cell.
Maximum sleeved dimensions are 21.6mm in diameter and 70.9mm in height, with a specified weight of no more than 73g. The established cylindrical format supports scalable series-parallel pack layouts while requiring appropriate cell holders, insulation, controlled spacing, secure fixing and dimensional allowance throughout the product lifetime.
Reliance specifies a maximum continuous discharge current of 50A with an 80°C cell-temperature cut-off. In the documented rate test, relative capacity remains at least 97% at 20A, 95% at 30A, 70% at 40A and 50% at 50A, clearly showing the capacity and thermal tradeoffs at extreme current.
Charging profiles include 3A standard charging, 6A rate charging and up to 12A continuous fast charging at permitted cell temperatures. Maximum charge current falls to 3A between 0°C and 15°C, 1.2A between -10°C and 0°C, and 0.3A between -20°C and -10°C.
Specified AC resistance is no more than 5.5mΩ when measured at 1kHz. During the manufacturer’s temperature test, relative capacity remains above 75% at -40°C using a 3A discharge and reaches at least 90% at -20°C using 30A, with temperature-specific voltage and thermal cut-offs applied.
Two 500-cycle profiles are documented at 25±3°C with 30A discharge. Capacity retention is at least 70% when charging at 6A and at least 60% when charging at 12A. These results demonstrate the effect of aggressive charging conditions, while actual pack life will depend on current, temperature, depth of discharge and storage.
Custom battery pack applications: The Reliance INR21700-RS60 is suitable for professionally designed power-tool packs, robotics, industrial equipment, portable power systems, light electric mobility and other applications requiring high energy with strong current output. MisenBattery supplies cells and supports custom pack integration with a compatible BMS, fuse protection, welded interconnects, individual-cell voltage and temperature sensing, insulation, controlled spacing, secure cell retention, and appropriate thermal and mechanical design. Supporting CE, UN38.3, RoHS and UL documentation can be provided for the applicable product and shipment; confirm document scope before ordering.
