The RC ERA C190 (H145) is a stunning 1/45 scale representation of the Airbus H145, known for its flybarless design and incredible stability. However, even the most advanced scale helicopter is only as good as the power source driving it.
To keep your “Eye in the Sky” performing at its peak, understanding the battery system is essential.
Battery Specifications
The C190 uses a proprietary modular battery design, which means you don’t have to fumble with messy wires inside the fuselage. It’s a “slide-in” unit that integrates seamlessly with the helicopter’s body.
- Type: Lithium-Polymer (LiPo)
- Configuration: 2S (7.4V)
- Capacity: Typically 1200mAh (depending on the specific bundle)
- Flight Time: Approximately 6–9 minutes
- Charging Port: USB (usually via a dedicated balance charging cable)
Common Battery Issues and Fixes
LiPo batteries are high-performance but sensitive. Here is how to troubleshoot common headaches:
1. Battery Swelling (“Puffing”)
The Issue: The battery looks bloated or rounded.
The Fix: Stop using it immediately. A puffed battery is a fire hazard. This usually happens from over-discharging (flying until the heli drops) or leaving it fully charged for weeks. Dispose of it safely at a local battery recycling center.
2. Shortened Flight Times
The Issue: Your 8-minute flight suddenly becomes 3 minutes.
The Fix: This is often “voltage sag” caused by aging cells. Ensure you are using the original charger. Also, avoid flying in extreme cold, as low temperatures significantly reduce LiPo efficiency.
3. Failure to Charge
The Issue: The USB charger flashes red or doesn’t react.
The Fix: Check the metal contact points on the battery module. If they are dirty or oxidized, gently clean them with a cotton swab and a tiny bit of isopropyl alcohol.
Replacement Method
Replacing the battery on the H145 is refreshingly simple compared to traditional RC helis.
- Power Down: Ensure the helicopter is switched off.
- Ejection: Most C190 models feature a latch or a “press-and-pull” mechanism at the rear or bottom of the fuselage.
- Slide Out: Firmly but gently slide the modular block out of the tracks.
- Inspection: Before inserting a new one, check the internal pins of the helicopter for any debris.
- Installation: Align the new battery module with the rails and push until you hear a “click.” If it doesn’t slide in easily, don’t force it—double-check the alignment.

Pro-Tip for Longevity
Never store your batteries fully charged or completely empty. If you aren’t planning to fly for more than 3 days, leave the battery at roughly 50% charge. This “storage voltage” prevents the chemistry from degrading and ensures your H145 is ready for the next sortie.
