2-Pack Ovonic 4S 10000mAh 14.8V 120C LiPo Battery with EC5 Plug for RC Car Airplane Truck

Overview

Operating large-scale RC vehicles, heavy lift drones, or high-speed boats demands massive current and long-lasting runtimes. Standard high-capacity packs are often inefficient, causing severe voltage drops and power sagging mid-run under heavy acceleration. This unexpected drop cut your run short and triggers premature electronic speed control (ESC) low-voltage cutoffs.

Ovonic 4S 10000mAh 14.8V 120C LiPo Battery Pack is engineered specifically to eliminate these runtime and sag problems. Packed with high-purity LiCoO2 cells, this massive 10000mAh pack provides an optimized energy-to-weight ratio, delivering a significant boost in running time without adding unnecessary dead weight. A relentless 120C discharge rate provides clean, stable power directly to your ESC, keeping your heavy-duty vehicles running longer and faster.

Applications

This heavy-duty, ultra-high-capacity 4S power pack solves power-fade issues across large-scale, high-current platforms:

• Large RC Airplanes, Scale Aircraft & EDF Jets: Supplies extended flight times and stable voltage for heavy servo and motor draws.

• Heavy-Lift Drones & Large Helicopters: Delivers consistent high-amperage output required to maintain stable flight control and vertical punch.

• 1/8 Scale RC Cars, Trucks, & Speedboats: Offers massive runtime for extensive track sessions and prevents thermal shutdown in watercooled ESC systems.

Five Key Features

• Massive 10000mAh Stamina: Provides exceptional runtime per charge, letting you enjoy extended sessions without frequent battery swaps.

• High-Burst 120C Current Draw: Feeds power-hungry brushless setups effortlessly, completely preventing mid-run voltage sag.

• Premium LiCoO2 Stacking Tech: Lowers internal resistance to help protect electronics, keeping operating temperatures down during high-amp runs.

• Pre-Soldered EC5 Plug: Equipped with low-resistance EC5 connectors to guarantee reliable power transfer and avoid plug overheating.

• Extended 450+ Cycle Life: High-grade materials deliver long-term value, maintaining consistent capacity over 450+ charge cycles.

Safety Notes

• Always use dedicated LiPo balance chargers (such as Ovonic Mate 1, X1, X4, or D15) and select correct cell counts.

• Never charge batteries unattended or exceed maximum charge rate of 1C.

• Inspect cell wrapping and wires for damage before installing in heavy setups.

• Store in fireproof LiPo safety bags at recommended storage voltage (3.8V–3.85V per cell).

• Keep battery packs away from high heat, direct sunlight, and moisture.
