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:

Safety & Operating Guidelines

• Voltage & Connector Check: Confirm that your drone ESC, motor KV, and power distribution board support 22.2V (6S) input and feature an XT90/XT90-S power lead.

• 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.
