2-Pack OVONIC 14.8V 4S 1550mAh 180C LiPo Battery with XT60 for 5" 4S FPV Freestyle Quadcopters

Overview

For 5-inch 4S FPV freestyle quadcopters, 1550mAh is the industry benchmark capacity, providing the ideal weight-to-power balance for aggressive trick execution.

The OVONIC 14.8V 4S 1550mAh 180C LiPo battery is designed specifically for standard 5-inch 4S freestyle quadcopters. Delivering a continuous 180C discharge rate, it maintains solid voltage delivery through intense power loops, punch-outs, and rapid trick recoveries without late-flight sag. Upgraded with an integrated balance lead storage slot on the casing, it locks the balance connector flush against the side wall to prevent prop strikes. Fitted with a gold-plated XT60 connector, this 175g softcase pack is sold in a value 2-pack.

Key Advantages

• 5" 4S Benchmark Capacity: 1550mAh volume provides the ideal thrust-to-weight ratio for 5-inch carbon freestyle frames.

• 180C Continuous Amperage Output: Low internal resistance prevents voltage drop under heavy current draw from 2207–2306 motors.

• Integrated Balance Lead Storage Slot: Secures the balance plug flush against the battery wall, keeping wires safely out of spinning props.

• Gold-Plated XT60 Interface: Heavy-duty connector handle prevents thermal power loss and plug deformation.

• Standard JST-XHR-5P Lead: Plug-and-play connection for precise per-cell balance charging.

Primary Applications & Compatibility

Specifically engineered for 14.8V (4S) FPV power systems using an XT60 main plug and battery mounting straps accommodating a 78 × 39 × 32 mm footprint:

• 5" FPV Freestyle Quadcopters: Native match for classic 5-inch 4S freestyle builds (e.g., ImpulseRC Apex 5", GEPRC Mark4/Mark5 4S, iFlight Nazgul5 V2 4S, TBS Source One V4/V5, and custom 5" carbon frames running 2207–2306 4S motors).

Safety & Operating Recommendations

• System Check: Confirm your ESC, flight controller, and PDB support 14.8V (4S) input and feature an XT60 main lead.

• Connector Connection: Push the XT60 plug firmly into your quad lead until fully seated.

• Charging: Charge exclusively using a dedicated LiPo balance charger on 4S balance mode. Cease charging immediately when each cell reaches 4.20V.

• Low-Voltage Warning: Set flight controller low-voltage warnings to at least 3.5V per cell. Do not discharge below 3.20V under load.

• Storage Maintenance: Store batteries at 3.80V–3.85V per cell inside a fire-retardant LiPo bag in a cool, dry place when inactive over 48 hours.
