Description

The PowerHobby 2S 4000mAh 7.4V LiPo battery lineup provides reliable power for a wide range of compatible RC cars, trucks, buggies, crawlers, boats, starter boxes, and racing applications. Each version offers the same 4000mAh capacity but features a different discharge rating, case style, connector, or physical configuration to meet the needs of specific RC models and electronics.

The 20C hardcase versions provide smooth, consistent power for general driving, crawling, boating, and recreational RC use. These batteries feature a durable hard-plastic case that helps protect the internal cells from impacts, vibration, and debris. Connector options include XT90, EC5, EC3, and Deans-style plugs, allowing customers to select the version that matches their vehicle or boat without replacing the factory connector. The 20C versions measure approximately 138 x 47 x 25.1mm and have a recommended charge rate of 1C.

The PH-2S-4000-20-EC3 version is specifically listed for the Pro Boat Blackjack 24-inch boat and includes an EC3 connector. It may also be used with other compatible applications requiring the same voltage, connector, polarity, discharge capability, and battery dimensions.

The PHB2S400050DNS is a round 50C LiPo battery designed for compatible RC starter boxes and other applications that use a round battery-pack configuration. Its 50C continuous and 100C burst discharge ratings provide strong, dependable power, while the factory-installed Deans-style connector allows easy connection to compatible equipment.

The PHB2S4000110 is a compact, high-output short drag-racing battery. Its 110C continuous and 220C burst ratings provide rapid acceleration and strong power delivery for demanding racing applications. The short 89 x 44 x 23.6mm configuration allows it to fit compatible drag-racing vehicles and other models requiring a compact, high-discharge 2S battery. The current product information confirms a JST-XH balance connector but does not specify the main discharge connection, so the connector configuration should be confirmed before use.

All of these PowerHobby LiPo batteries include a six-month limited warranty against defects in materials and workmanship from the original purchase date. The warranty does not cover damage caused by crashes, hard landings, improper mounting, physical deformation, overcharging, deep discharging, or excessive discharge current.

Always confirm the voltage, connector type, connector polarity, battery dimensions, discharge requirements, and available battery-compartment space before installation. Charge only with a LiPo-compatible balance charger using the appropriate settings.
