With 6,600mAh of capacity, a rated flight time of up to 30 minutes, and an integrated Battery Management System (BMS) that communicates directly with the SplashDrone 4 flight controller, the IB4 is far more than a standard lithium pack.\u003c\/p\u003e\n\n\u003cp\u003eWhether you're dropping live baits over offshore structure in New South Wales, running surface-launched missions from a kayak in Western Australia, or targeting pelagic species along the Queensland coast, the IB4 provides the power, intelligence, and reliability your SplashDrone 4 needs to perform safely in remote and offshore Australian fishing environments.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Makes the IB4 \"Intelligent\"?\u003c\/h2\u003e\n\n\u003cp\u003eUnlike the simple LiPo packs used in many consumer drones, the IB4 is classified as an intelligent battery because of its integrated Battery Management System (BMS) — a microprocessor-controlled circuit embedded within the pack that actively monitors and protects the cells during charging, storage, and every flight.\u003c\/p\u003e\n\n\u003ch3\u003eBMS Protection Features\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOver-charge protection:\u003c\/strong\u003e Prevents cells from being charged beyond their safe maximum voltage (4.2V per cell, 16.8V total for the 4S pack). Over-charging is one of the primary causes of lithium battery fires — the BMS eliminates this risk automatically without requiring manual voltage monitoring by the user.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOver-discharge protection:\u003c\/strong\u003e Cuts power delivery before cells fall below the safe minimum voltage, preventing the irreversible cell damage that occurs when standard packs are discharged too deeply during long offshore missions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShort-circuit protection:\u003c\/strong\u003e Detects and interrupts abnormal current draw within milliseconds — protecting both the battery's cells and the SplashDrone 4's power electronics in the event of a wiring fault or connector issue.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature monitoring:\u003c\/strong\u003e The BMS monitors cell temperature continuously during charge and discharge. If temperature exceeds safe operating limits, charging is automatically suspended — critical for protecting cells during warm Australian summer sessions on exposed surf beaches.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eReal-Time Charge Indicator and Fuel Gauge\u003c\/h3\u003e\n\n\u003cp\u003eThe IB4 features a built-in LED charge indicator that displays remaining battery level directly on the pack — no need to power up the SplashDrone 4 to check charge state. During a session rotation, a quick glance at the LED array confirms whether a battery is ready to install or still needs more charge time.\u003c\/p\u003e\n\n\u003cp\u003eWhen installed in the SplashDrone 4, the BMS communicates remaining capacity data to the flight controller, enabling the drone to display accurate remaining flight time — not just a rough voltage percentage — in the SplashDrone 4 app. This allows precise mission planning: you know exactly how long you have to complete an offshore bait run and return safely to shore before the reserve threshold triggers automatic RTH.\u003c\/p\u003e\n\n\u003ch2\u003e4S LiPo Chemistry — Completely Different From Fisherman Series Batteries\u003c\/h2\u003e\n\n\u003cp\u003eThe SplashDrone 4 IB4 uses \u003cstrong\u003e4S LiPo (Lithium Polymer)\u003c\/strong\u003e chemistry with a nominal voltage of 14.8V and a maximum charge voltage of 16.8V (4.2V × 4 cells).
