KF603 3.7V 800mAh Battery JST Plug for Galaxy Ship RC Airplane

Extend Your Flight Time, Fix Low-Power Sag, and Replace Swollen Flight Batteries

Short flight times, sagging motor power during water takeoffs, or dead batteries that refuse to hold a charge ruin the multi-terrain fun of your Galaxy Ship KF603 RC Airplane. Overcharging or prolonged storage often leads to swollen cells, shortened runtimes, or sudden in-flight power cutoffs that force emergency land or water landings. Using generic batteries with incorrect connector polarity or improper dimensions can damage internal ESC circuitry or disrupt the aircraft's center of gravity. This official KF603 3.7V 800mAh Battery with JST plug completely resolves battery degradation and power loss. Engineered specifically for the KF603 compartment, this high-density LiPo pack delivers stable voltage output and extended flight sessions across land, sea, and air operations.  Ships worldwide.
