RC ERA C129 Modular Battery 3.7V 300mAh 25C LiPo for 4CH RC Helicopter
Eliminate Charging Delays, Restore Throttle Punch, and Extend Indoor Flight Time
Short airtime and long USB charging waits disrupt your flying sessions with the RC ERA C129 V2 4CH RC Helicopter. Over time, original LiPo batteries lose their discharge efficiency, causing reduced head speed, poor altitude hold stability, and premature low-voltage cutoffs during 3D flip maneuvers. Traditional bare-wire battery setups can be tricky to plug in, strain internal power sockets, or shift off-center inside the airframe. This official RC ERA C129 Modular Battery resolves all battery handling hassles. Featuring a tool-free slide-in modular casing with a high-rate 25C discharge cell, this spare battery allows you to swap fresh power cartridges instantly in the field without fiddling with loose wires, restoring punchy throttle acceleration, steady hovering performance, and extended flight sessions.Ships worldwide.
Product Highlights
Tool-Free Slide-In Cartridge Design: Rugged hard-case module slides smoothly into the helicopter fuselage bay for fast, hassle-free battery swaps.
High-Rate 25C Continuous Discharge: Engineered to deliver sustained high-current output for responsive pitch control, snappy recovery, and energetic 3D flip maneuvers.
Factory Weight & CG Optimization: Precisely calibrated weight distribution maintains the ideal center of gravity for rock-solid altitude hold and 6-axis gyro tracking.
Built-In Overcharge & Safety Circuit: Integrated protection circuitry safeguards the battery during USB charging, extending overall cycle life and cell durability.
Removing Expended Battery Module: Pinch the release tabs on the underside of the C129 V2 fuselage and gently pull the depleted battery cartridge rearward.
Inserting Fresh Modular Battery: Align the contact guide rails of the RC ERA C129 Modular Battery with the inner nose compartment slot and push firmly until locked with a secure click.
USB Charging Guidelines: Connect the battery cartridge to the original C129 USB charger; disconnect promptly once the charging status light changes to preserve cell health.
Pre-Flight Power Check: Power up the aircraft on a level surface, allow the 6-axis gyro to auto-calibrate, and confirm a solid status LED before spooling up.
