HJ806 RC Boat 7.4V 2800mAh JST Battery High-Capacity Lipo Spare Part

Extend Your Water Action, Eliminate Unexpected Power Shutdowns, and Maximize Speed Performance

Running out of power mid-session or experiencing thermal voltage drops during high-speed RC boat racing can interrupt your fun and leave your vessel stranded far from shore. Standard stock batteries often lack the capacity needed for extended high-throttle runs across the water. The HJ806 RC Boat 7.4V 2800mAh JST Battery is the perfect original-fit high-capacity solution. Engineered with high-drain cells and a reliable red JST connector, this rechargeable LiPo battery ensures longer runtimes, consistent power output to the water-cooled motor, and seamless plug-and-play installation for non-stop racing. Ships worldwide.
