Align the battery mount (discharge case) with the rear rack of your e-bike. Ensure the slots on the rack match the mounting holes in the case.
Not very clear how to operate but after a number of attempts seems to be successful and will become a useful tool some instructions would have been useful
Good quality Samsung cells in this battery Replaced my 3 old batteries bought elsewhere on ebay, all of which failed. Great customer support and communication. Highly recommended
Fantastic quality prompt delivery
