GNB 1550mAh 6S1P 22.2V 120C Lipo Battery - High Discharge FPV Racing Drone Pack Low IR Cell

The GNB 1550mAh 6S1P 22.2V 120C Lipo Battery delivers an incredible power-to-weight ratio tailored strictly for high-demand drone racing and freestyle configurations. Featuring high-purity raw materials and robust internal cell building, this 22.2V pack keeps your power rail perfectly smooth even through hard sudden pulls. By offering a flatter voltage discharge curve, it ensures FPV pilots maintain strong terminal punch throughout the entire duration of their aggressive acrobatic flight profiles.

Key Features :

• Unmatched 120C Discharge Rate: Provides instant delivery pathways to comfortably handle extreme high-amp burst demands up to 240C without internal cell damage.

• Low Internal Resistance Chemistry: Optimized lithium compound structure minimizes thermal output and stops premature low-voltage sag under load.

• High-Flex Silicone Leads: Outfitted with 12AWG multi-strand power cables and a reinforced JST-XH balance lead for high field durability.

• Compact Footprint Geometry: Tightly stacked cell configuration yields maximum energy density while easily fitting standard 5-inch drone battery straps.

Use Cases :

• Primary power source for 5-inch to 6-inch high-performance FPV racing and extreme freestyle quadcopters.

• High-output battery cells for compact cinematic drones, heavy-carrying cinewhoops, and FPV chase targets.

• Premium power solution for lightweight, long-range custom fixed-wing models and commercial multirotors.

Frequently Ask Questions :

Q1 ) Can I charge this high-discharge 6S battery using standard LiHV charger settings?

Ans : No. This pack is a standard Lithium Polymer chemistry with a maximum charging ceiling of 4.20V per cell (25.2V total for the 6S loop). Charging this pack on a LiHV profile up to 4.35V per cell will cause severe cell swelling, permanent degradation, or dangerous thermal failure.

Q2 ) What is the lowest safe resting voltage limit for this 1550mAh battery?

Ans : To maintain long-term cell lifecycles, configure your flight controller's telemetry alarms to warn you at 3.5V per cell under flight load. Land your multirotor promptly so that the resting voltage settles back to a safe baseline of 3.7V to 3.75V per cell.

Q3 ) What is the fastest safe charge rate for this pack when at the flying field?

Ans : While a standard balance charge rate of 1C (1.55A) is ideal for preserving your battery's internal lifespan, the R-Line grade construction of this GNB cell can safely handle high fast-charging parameters up to 3C (4.65A) on smart balance systems.

Q4 ) Why does my drone maintain better punch with this 120C pack over a 60C battery?

Ans : The massive 120C continuous performance capacity indicates a significantly lower internal resistance structure. Under hard full-throttle punch-outs, the pack transfers raw current much more efficiently, preventing the large voltage drops that make 60C alternatives sag early.

Q5 ) How should I handle storage prep if the weather stops my weekend flying plans?

Ans : Do not leave your drone batteries sitting fully charged to 25.2V or fully flat below 21.0V for more than 48 hours. Connect the packs to your balance charger and run a dedicated storage cycle to bring every cell to a stable resting level between 3.80V and 3.85V.
