PG3665 Description

This product will be no longer available from December 2016 because the special cells used are no longer available from the supplier. It should not be designed into new devices in its current form.
Please contact us for details of alternate products for your application.

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
