GNB 550mAh 4S 90C LiPo Battery Long (XT30)

The GNB 550mAh 4S 90C battery features an elongated "Long" form factor engineered specifically for 3-inch toothpick builds, micro freestyle quads, and lightweight cinewhoops where a slim, narrow profile is required to fit along thin frame plates and optimise the pitch axis centre of gravity. Utilising high-voltage LiHV cell chemistry with a 15.2 V nominal rating, this pack delivers high energy density while keeping overall takeoff weight minimal for demanding sub-250 g builds.

Key features

• Elongated geometry easily mounts onto narrow top plates and fits under low-profile micro canopies without widening the aerodynamic cross-section.
• High-voltage LiHV chemistry allows charging up to 4.35 V per cell (17.4 V fully charged), providing higher initial RPM and reduced voltage sag under load compared to standard 4.20 V cells.
• Delivers up to 180C burst discharge currents to sustain aggressive throttle punches, sharp cornering, and rapid freestyle recoveries.
• Pre-soldered with a high-conductivity XT30 discharge plug and a durable silicone-sheathed JST-XH balance lead.
