Frequently asked questions

What battery does the FLX Blade use?

The FLX Blade (2018) uses a 48V 17.5Ah, 840 Wh battery from LG (Lithium-ion).

How far can the FLX Blade go on one charge?

A higher amp-hour pack at the same 48V voltage adds range, as long as it fits the mount and connector. Do not use a higher-voltage pack unless the controller is rated for it.
