Good, some question for my case needed additional research in the manual from the OEM. Not sure if it would make sense to update the online product information, except linking directly to resources of the OEM such as data sheet and manual.
Packages are great.

Less upselling with spares and accessories. Instead offer two versions, one cheap with the basics and one (or two) with the most common accessories. If customers want a more customised offer they need to configure it themselves. You might want to consider discounts when spending is large enough.
Better battery portfolio would be good too.
