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):
| Discharge Current | Relative Capacity |
|---|---|
| 1.2A (0.2C) | 100% |
| 3A (0.5C) | ≥96% |
| 6A (1C) | ≥95% |
| 12A (2C) | ≥93% |
| 20A (3.33C) | ≥90% |
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):
| Temperature | End Voltage | Relative Capacity |
|---|---|---|
| 25℃ | 2.5V | 100% |
| 0℃ | 2.5V | ≥85% |
| -10℃ | 2.0V | ≥80% |
| -20℃ | 2.0V | ≥80% |
| -40℃ | 1.5V | >65% |


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
| Model | Capacity (Typ.) | ACIR | Max Cont. Discharge | Low-Temp Discharge | Weight |
|---|---|---|---|---|---|
| RENLIN RH60 | 6000mAh | ≤7mΩ | 20A | -40℃ ≥65% | ≤71g |
| Amprius SA112 | 6500mAh | ≤22mΩ | 13A | -20℃ ≥? | 72g |
| FEB 21700 6000 | 6000mAh | ≤25mΩ | 12A (2C) | -20℃ ≥70% | ≤75g |
| Joinsun 21700 60D | 6000mAh | ≤22mΩ | 12A | -20℃ ≥65% | ≤75g |
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.
