This adapter lets a Kobalt 24V Max lithium battery power a Dyson V7 or V8 cordless vacuum. It is a molded ABS converter, not a 3D-printed part, with a built-in protection circuit and a latch meant to hold the vacuum and battery together. It suits owners who already have Kobalt 24V batteries and a V7 or V8 whose original battery has failed. Against buying a Dyson replacement battery, it reuses packs you own, but it adds bulk and depends on the Kobalt pack's capacity and health.

This adapter lets a Kobalt 24V Max lithium battery power a Dyson V7 or V8 cordless vacuum. It can be used when the original Dyson battery is damaged. The base accepts the Kobalt battery, and the top plugs into the vacuum.
The adapter is made by precision injection molding, not 3D printing. The housing locks the vacuum and battery together so they do not loosen or slip off. It has built-in over-discharge, over-voltage, over-current and over-temperature protection, and it complies with FCC, RoHS and CE testing standards.
To install it, insert the Kobalt battery into the base of the adapter, then plug the adapter into the vacuum. An indicator light shows battery status: green means it is working normally, and red means the battery is low. The adapter cannot charge the battery, so use the battery's original charger. Remove the adapter from the battery when not in use. Batteries of 4Ah to 5Ah are recommended because of the vacuum's high power. With a smaller battery, use the vacuum's low-speed mode.
