11.1V 2000mAh Li ion Battery Pack with USB Charger and Conversion Cables Key features and specifications Package includes: 2 batteries, 2 USB charging cables, 4 conversion cables. Battery specifications: 11.1V nominal voltage, 2000mAh capacity, 3S configuration, Li ion chemistry. Physical: 72 g per battery, size 105 x 18 mm, discharge connector SM2P, charging interface XH4P. Charger specifications: 11.1V USB charging cable, input DC 5V 23A, output DC 11.1V 2A, four pin balanced charging plug. Charging indicators: red power indicator lights when cable is connected to power; green charging indicator flashes slowly while charging and stays solid when fully charged. Included conversion cables: multiple SM2P conversion cables including SM2P to T plug and other common RC connector options to improve compatibility. Why this product helps Ready to use and compatible: two batteries plus conversion cables make it easy to power and adapt to a range of RC devices that accept 3S 11.1V packs with SM2P discharge connectors. Balanced, safer charging: the USB charging cable contains an intelligent charging management IC that separates and balances the three cells and uses a three stage charging method constant current, constant voltage, and pulse to fully charge the pack while helping preserve battery life. Portable and lightweight: compact 105 x 18 mm cells weighing 72 g each fit into small battery compartments and reduce added weight for mobile RC applications. Convenient charging: USB input allows charging from common 5V power sources while delivering a regulated DC 11.1V 2A output for the pack. Compatibility and typical use cases Airsoft gel water droplet blaster and air gun models that accept 11.1V Li ion packs and SM2P discharge connectors. Remote control aircraft and drones that use 3S 11.1V batteries and require balanced charging via a four pin balance plug. Electric RC cars, trucks, or boats that are compatible with 3S 11.1V packs and benefit from included conversion cables for connector matching. Additional product details Battery connector plug type: SM2P. Charging plug model: XH4P four pin balanced plug. Materials and construction: cables and connectors are made from durable materials designed for repeated use and reliable connection. Battery safety and precautions 1.
