The PG3665 high power density smart battery is ideal for use with 24V DC motors for robotics or enabling motion in devices operating "off the grid". It uses the latest Li Ion cell technology which enables it to deliver much higher currents than regular Li Ion battery packs. Due to its higher operating voltage and high current capability, it uses a new standard connector & requires a different charger to our regular "N-series" standard batteries. Its rugged construction reflects it application in mobile environments

You can buy any quantity from a single battery up to many thousands, all direct & built-to-order from Inspired Energy. For information on how we can hot-rod your off-the-shelf PG3665  smart Li ion battery, details of volume pricing or any additional data on the PG3665, please contact us at:
