For sectionals or larger sized power pieces, the E10 Power Battery for 1-4 Motors will be an impressive companion. It allows for up to 2000 motorized functions without a power outlet on a single charge, and is the most efficient for its size in the industry. It has an LED power indicator and a buzzer alert for an audible charging reminder, or visualize your pack's power level, review charging history, receive low power alerts/recharge reminders, and shut off power remotely in the app to conserve power when your pack is not in use.
