Hi, yes, cordless mowers can be very effective on slopes. Interestingly, a lightweight non-self-propelled mower can often be a better choice than a heavier self-propelled model, particularly when you need to lift the mower or move it between the lawn and your storage area.

The best choice really depends on your specific lawn size and requirements, so I recommend using my selection tool here to find the right fit for you: https://easylawnmowing.co.uk/find-the-best-lawnmower/
