The Redcat Racing RER42142 is a specialized USB-powered charger designed specifically for the 3-cell (3S) LiPo batteries used in the Ascent-18 Apex platform. Because the Apex runs on a higher-voltage 11.1V system compared to standard 1/18 crawlers, it requires this specific charger to safely balance and peak its 3S batteries.
Key Features
-
3-Cell (3S) Optimization: Specifically engineered to charge 11.1V LiPo batteries, stepping up power from a standard 5V USB source to the required 12.6V peak charge voltage.
-
Safe 0.2A Charge Rate: The low 200mA (0.2amp) output is designed to be gentle on the small-capacity batteries (typically 200–300mAh) used in the Ascent-18 Apex, maximizing their overall lifespan and health.
-
USB-A Versatility: Can be powered by any standard USB port, including computer ports, phone wall adapters, or portable power banks for field charging.
-
Integrated Balance Charging: Connects via the battery's balance lead to ensure each of the three cells is charged to the same voltage, which is critical for preventing battery failure or fire.
-
Status LED: Features an indicator light that changes color or turns off to signal when the battery has reached a full charge.
