2-Pack OVONIC Roam Series 22.2V 5500mAh 150C 6S LiPo Battery Pack with XT90-S Anti-Spark Connector for 7–10 Inch Long-Range FPV Drones and X8 Cinelifters

Overview High-payload cinema drones, 7–10 inch long-range quadcopters, and heavy-duty X8 Cinelifters require high continuous amperage and sufficient energy reserves to safely transport expensive HD camera gear. Additionally, plugging in high-capacity 6S batteries can generate extreme arcing sparks that degrade connectors and damage ESC filter capacitors over time. OVONIC Roam Series 22.2V 5500mAh 150C 6S LiPo Battery Pack solves both challenges by combining a manufacturer-rated 150C continuous discharge rate (300C peak burst) with an integrated XT90-S Anti-Spark connector. Packing 5500mAh capacity, this 6S softcase pack maintains throttle authority and voltage stability during high-load maneuvers, long-distance flights, and cinematic filming runs. The anti-spark technology pre-charges ESC capacitors upon connection, extending the electrical lifespan of your power distribution system. Primary Applications & Compatibility Designed for 6S (22.2V) power systems utilizing XT90 or XT90-S connectors and battery mounting platforms accommodating dimensions of 138 × 43 × 61 mm: 7–10 Inch Long-Range & X8 FPV Cinelifters: Fits heavy-lift platforms including the iFlight Helion 10 O3, Proxima 6 Cinelifter, Centurion X8 O3, Taurus X8 V3, GEPRC MARK4 series (MK5D-LR7, MARK4 LR8, MARK4 LR10), and custom 400mm–450mm X8 multirotors. 700–800 Class RC Helicopters & Aerobatic Aircraft: Provides steady voltage for 700mm to 800mm size helicopters (Align T-REX, SAB Goblin) and large 3D aerobatic planes requiring 6S softcase power. Large EDF Jets & Scale Aviation: Compatible with FMS EDF jets and large-scale RC airplanes requiring high-discharge 6S batteries. 1/7 & 1/8 Scale High-Speed RC Surface Models: Suitable for high-power RC cars, trucks, and marine craft using XT90-S connections. Key Features 150C Continuous / 300C Burst Rating: High-discharge cell chemistry reduces voltage drop during full-throttle acceleration and heavy camera payload lifts. XT90-S Anti-Spark Connector: Built-in internal resistor eliminates spark arcing during plug connection, protecting ESC capacitors and battery terminals from electrical shock. 5500mAh Capacity Reserve: Provides an optimal balance between extended flight times and structural payload weight. Roam Series High Power-to-Weight Balance: Engineered softcase housing maintains structural integrity in a 138 × 43 × 61 mm footprint weighing 753g per pack. Standard JST-XHR-7P Balance Lead: Allows individual cell monitoring and balancing on standard LiPo balance chargers.

Anti-Spark Connection: Push the XT90-S connector fully home in one smooth motion so the built-in resistor pre-charges the ESC before full contact is established. Charging Instructions: Charge exclusively using a dedicated LiPo balance charger on 6S balance mode. Cease charging immediately when each cell reaches 4.20V. Never leave charging batteries unattended. Low-Voltage Protection: Configure flight controller low-voltage warnings to at least 3.5V per cell. Do not allow cell voltage to drop below 3.20V under load. Storage Maintenance: For storage periods longer than 48 hours, store batteries at 3.80V to 3.85V per cell in a cool, dry place inside a fire-retardant LiPo bag.
