Product Description (Detailed):
Ensure the longevity and optimal performance of your Lithium Polymer (LiPo) batteries with the iMaxRC B3 Compact Charger, a highly efficient and user-friendly 2S/3S LiPo battery balance charger. Designed for hobbyists and RC enthusiasts, this charger provides crucial balance charging capabilities, ensuring that each cell within your 2-cell (7.4V) or 3-cell (11.1V) LiPo pack is charged to an identical voltage. This intelligent balancing process is vital for preventing overcharging of individual cells, which can lead to reduced battery lifespan and potential safety hazards. The iMaxRC B3 features a direct AC input (100-240V), eliminating the need for an external power supply and making it incredibly convenient for use at home or on the go. Its intuitive LED indicators clearly display the charging status for each cell (typically red for charging, green for fully charged), providing immediate visual feedback. With a typical balance current of 850mA per cell and integrated safety features like overcharge protection and short-circuit protection, the B3 offers a reliable and safe charging solution for your RC drones, cars, planes, and other LiPo-powered devices. Maximize your battery's health and minimize risks with this essential compact charger.
The iMaxRC B3 Compact Charger is a reliable and easy-to-use LiPo balance charger for charging 2-cell (2S) and 3-cell (3S) lithium polymer batteries used in RC vehicles, drones, and aircraft. With its built-in balance function, it ensures each cell in your battery is charged evenly, which extends battery life and improves performance.
The LED indicators provide real-time charging status:
This charger is lightweight, portable, and safe, making it ideal for beginner and advanced RC users alike. Just plug the charger into an AC outlet, connect your battery's balance connector, and it starts balancing automatically.
