2-Pack OVONIC Roam Series 22.2V 3300mAh 150C 6S LiPo Battery Pack with XT90 Connector for 6–7 Inch Long-Range FPV Drones and Cinelifters

Overview

Long-range FPV quadcopters, 7-inch endurance rigs, and HD Cinelifters require an optimal capacity-to-weight balance to achieve long flight times without overloading motors or ESCs. Using lower capacity or low C-rated battery packs can result in severe voltage sag during punch-outs, reduced flight times, and thermal stress under heavy camera payloads.

OVONIC Roam Series 22.2V 3300mAh 150C 6S LiPo Battery Pack is engineered specifically for 6- to 7-inch long-range FPV drones, multirotors, and Cinelifters. Delivering a manufacturer-rated 150C continuous discharge rate (300C peak burst) and 3300mAh capacity, this 6S softcase pack provides stable voltage under high throttle demands and supports extended flight times of up to 9+ minutes under optimal flight conditions. Pre-fitted with a high-current XT90 main discharge plug and a JST-XHR balance connector, it ensures low internal resistance and safe current delivery for demanding FPV operations.

Primary Applications & Compatibility

Designed for 6S (22.2V) FPV power systems using XT90 connectors and battery mounting spaces measuring at least 139 × 43 × 40 mm:

• 6–7 Inch Long-Range FPV Quads: Fits popular long-range platforms including the iFlight Chimera7 Pro V2 6S HD, iFlight BOB57 O3 Cinematic 6S HD, GEPRC MOZ7, GEPRC Crocodile75 V3, and custom 6-inch to 7-inch long-range builds.

• Cinelifters & X-Class Multirotors: Provides stable power for HD cinema rigs and aerial photography platforms carrying heavy camera gear.

• Large-Scale FPV & Aviation Models: Suitable for high-power fixed-wing aircraft, 6S EDF jets, and DIY multirotor platforms requiring high-amperage 6S LiPo power.

Key Features

• 150C Continuous Discharge Rate: High-discharge cell chemistry minimizes voltage sag during power spikes, keeping flight controllers and video transmitters powered reliably.

• 3300mAh Capacity Reserve: Strikes a balance between flight endurance and weight distribution, enabling extended flight sessions without dragging down agility.

• Optimized Power-to-Weight Architecture: Engineered softcase construction delivers high structural integrity in a 139 × 43 × 40 mm profile weighing 471g per pack.

• Factory-Fitted XT90 Connector: Equipped with a gold-plated XT90 main plug and heavy-duty silicone leads to prevent heat buildup and plug melting under sustained current draw.

• JST-XHR-7P Balance Port: Standard balance lead for precise cell voltage balancing and telemetry monitoring.

Safety & Operating Guidelines

• Voltage & Plug Verification: Confirm that your drone ESC, motor KV, and power lead are rated for 22.2V (6S) and equipped with an XT90 plug before flying.

• Charging Instructions: Charge exclusively using a dedicated LiPo balance charger set to 6S balance mode. Cease charging immediately when each cell reaches 4.20V. Never leave charging batteries unattended.

• Low-Voltage Protection: Configure your flight controller or telemetry OSD low-voltage alarm to at least 3.5V per cell. Do not allow cell voltage to drop below 3.20V under load.

• Initial Conditioning: If a new pack shows slight cell voltage variance out of the box, perform 2 to 3 low-amperage balance charge/discharge cycles to balance cell resistance.

• Storage Maintenance: For storage periods longer than 48 hours, maintain a storage voltage between 3.80V and 3.85V per cell in a cool, dry area inside a fire-retardant LiPo bag.
