RC ERA C189S Modular Battery 7.4V 1200mAh LiPo for Dual Brushless RC Helicopter
Eliminate Short Flight Sessions, Power Dual Brushless Motors, and Fix Sudden Power Cutoffs
Short airtime and long recharging waits can spoil your flying experience with the high-performance RC ERA C189S Dual Brushless RC Helicopter. Dual brushless motors demand continuous high-voltage power; aging or degraded batteries suffer from rapid voltage sag, leading to sluggish scale maneuvers, compromised optical flow position holding, and premature low-voltage land warnings. Loose-wire battery setups can be frustrating to connect inside scale fuselages, risk cord pinching, and throw off flight balance. This official RC ERA C189S Modular Battery solves all battery management hassles. Featuring a tool-free slide-in modular housing packed with high-capacity 7.4V 1200mAh LiPo cells, it enables instant cartridge swaps in the field to maintain peak brushless power, steady optical flow hovering, and extended scale flight operations.Ships worldwide.
1 x RC ERA C189S 7.4V 1200mAh Modular Lithium Battery
Product Highlights
Tool-Free Slide-In Hard Shell Module: Durable hard-case cartridge slides directly into the C189S scale tail/fuselage bay for instant, hassle-free battery swaps without loose wiring.
High-Capacity 7.4V 1200mAh LiPo Power: Specifically engineered to supply continuous current to dual brushless motors and optical flow sensors for maximum flight duration.
Factory Weight & Scale Balance Calibration: Precision-weighted casing maintains the exact center of gravity necessary for hands-free optical flow position hold and smooth scale flights.
Built-In Overcharge & Circuit Protection: Integrated protective PCM board safeguards cells during USB charging and prevents damage from over-discharging during flight.
Install Tips
Removing Expended Battery Module: Press the release catch on the C189S battery compartment and slide the depleted 7.4V cartridge straight out of the rear fuselage.
Inserting Fresh Modular Battery: Align the guide tracks of the RC ERA C189S Modular Battery with the internal compartment slot and push firmly until the locking tab clicks into place.
USB Charging Procedure: Connect the modular cartridge to the original C189S USB balance charging cable, unplugging it promptly once the indicator turns solid green.
Pre-Flight Gyro & Power Test: Place the helicopter on a flat, level surface, power on the system, and confirm a solid optical flow signal link before spooling up the dual brushless motors.
