Extended runtime for the Assist Slim
This bundle pairs the larger Slim Endurance Battery with its dedicated 28V charger. At 241Wh, the Endurance Battery extends runtime on the Assist Slim system, delivering lower thrust than the Performance Battery in exchange for longer sessions thanks to its reduced voltage.
The battery is IP68 rated with a single power plug — larger connectors for power, smaller for charging — and comes with a protective dust cap for storage and transport. It requires the 28V Standard Charger included in this bundle; using a 40V charger will damage the battery.
Key Features
