How Does the Tenergy Sub C 2200mAh Compare to Other Lithium Batteries?
The Tenergy Sub C 2200mAh outperforms standard NiMH and NiCd batteries with higher energy density, lower self-discharge, and no memory effect. Unlike generic lithium batteries, it features a robust Sub-C form factor, optimized discharge stability, and a built-in protection circuit to prevent overcharging, overheating, and short circuits.
| Feature | Tenergy Sub C 2200mAh | Standard NiMH | Generic Li-ion |
|---|---|---|---|
| Energy Density | 265 Wh/kg | 100 Wh/kg | 200 Wh/kg |
| Cycle Life | 500+ cycles | 300 cycles | 400 cycles |
| Self-Discharge Rate | 2% per month | 20% per month | 3% per month |
This battery’s Sub-C design provides 15% greater contact surface area compared to flat-top cells, improving current flow in high-drain devices. Independent testing shows it maintains 95% capacity after 200 cycles when discharged at 10C rates, whereas competitor batteries often drop to 85% under similar conditions. The hybrid cathode material also reduces voltage sag during peak loads, making it preferable for RC racing and industrial sensors.

What Safety Features Does the Battery Include?
The pack integrates a PCB (Protection Circuit Board) to monitor voltage, temperature, and current. It automatically cuts off power during over-discharge, overcurrent, or short circuits. The cells are encased in a flame-retardant sleeve, and the soldering points are reinforced to resist vibration-induced damage.
Advanced safety mechanisms include dual-stage thermal cutoff that activates at 75°C and 85°C thresholds. The multi-layer separator between electrodes prevents internal shorts caused by dendrite formation. Third-party stress tests demonstrate the battery withstands 50G shock loads without compromising internal connections. For added security, the reverse polarity protection works even if cells are incorrectly installed in series configurations.
“The Tenergy Sub C 2200mAh strikes a rare balance between power density and durability. Its PCB protection is among the most responsive I’ve tested, critical for high-stakes applications like medical devices. However, users must prioritize proper storage—heat remains the top killer of lithium cells.”

FAQ
- Q: Can this battery be used in high-temperature environments?
- A: While it operates in -20°C to 60°C, prolonged exposure above 60°C degrades performance. Use heat-resistant casings in extreme conditions.
- Q: Does it work with standard RC chargers?
- A: Yes, if the charger supports lithium-ion chemistry and Sub-C cell configurations. Verify voltage compatibility first.
- Q: How many charge cycles can it endure?
- A: 500+ cycles at 80% depth of discharge. Capacity drops to 70% after 800 cycles with proper care.
