Description
Keep your Black Marlin on the water longer with this genuine replacement 1500mAh Li-ion Battery. Designed specifically for the hull geometry and power system of Rage R/C’s brushed deep-V boats, this pack delivers the consistent 7.4V power needed for stable planing and responsive steering.
Unlike standard rectangular hobby packs, this cylindrical-cell Li-ion pack is shaped to fit snugly into the battery tray of the Black Marlin, preventing weight shifts that can capsize the boat during high-speed turns.
Key Features
-
Direct Fit: Engineered to match the exact dimensions and weight distribution of the Black Marlin chassis.
-
Li-ion Chemistry: Offers a safe and reliable power density, holding its charge well between runs compared to older NiMH packs.
-
Factory Connector: Pre-soldered with a T-Plug (Deans Style) connector, ensuring a high-current, low-resistance connection to your boat’s ESC.
-
Round Cell Configuration: Uses cylindrical Li-ion cells (typically 18650 size) wrapped in a stick-pack format, which is more durable against impacts than soft-pack LiPos.
Compatibility
-
Rage R/C Black Marlin (Brushed Version)
-
Rage R/C Black Marlin EX (Brushed Version)
Important Tech Note: Brushed vs. Brushless
Check your boat version before buying!
-
This Battery (7.4V Li-ion): Is for the Brushed motor versions of the Black Marlin / Black Marlin EX.
-
Brushless Version: If you have the Black Marlin EX Brushless (Part # RGRB1405), that boat typically runs on a 3S 11.1V LiPo. While this 2S battery might plug in, it will result in significantly slower speeds and may not fit the larger tray perfectly.
