The AR Li+ 3K Smart Battery combines intelligent design, high performance, and ease of use to keep your RC models powered safely and efficiently. Equipped with 10 multi-coloured daylight-readable LEDs, the battery instantly displays remaining capacity the moment your model is powered, giving you a clear visual indication of pack health every flight. A simple push of a button also allows quick manual checks.

Designed for professional and hobby pilots alike, the AR Li+ 3K features built-in self-balancing cells to ensure optimal performance, along with a Smart Storage Mode that automatically discharges the battery for safe end-of-season storage. All pack data is stored internally and can be accessed via the AR Smart Battery Charger for monitoring and logging.

For seamless integration, the battery uses the high-speed AR1 CAN bus connector for full data communication with AR Smart systems but can also be fitted with popular industry connectors like XT60, XT30, MPX, or EC3 via adapters. Optional aluminium battery trays with easy-release Velcro straps make transferring the pack between models quick and convenient.

Available in multiple capacities, the AR Li+ 3K is ideal for medium-sized models needing high current output with reliable monitoring and control.
