V8 Battery Adapter for Dewalt 20V Lithium Battery Converted to Replace for Dyson V8 Battery, Works with Dyson V8 Series Animal Absolute Vacuum Cleaner(DW20V8 Adapter ONLY)

I have 2aH and 5aH batteries and this adapter fits both and allows extended run-time on my V8. It works on Max Suction or normal suction. I have not tried my 60V DeWalt batteries. Good buy if youre already invested in the DeWalt system.

Unfortunately this product only works for low suction. As soon as you switch it to max suction the battery light flashes red and shuts off. I dont know about you, but the low suction on my Dyson isnt even worth it. Waste of time & money with this attachment.

Saved me from having to throw away our Dyson. Better than it was new, now.

After installation if I try to run the Dyson V8 on Max Suction, it will run for1 sec and stop. Only works on Low suction mode.

I had the exact same problem as other users where the 20V 2ah battery didnt work longer than 10-20sec. I installed my 20v/60v 5ah battery and it worked fantastic. I assume a 20V with larger amp hour would work, but I only have an order small capacity 20V battery.

Thank you random TikTok-er showing me that this existed! I can vacuum for dayssssssss now.

My Dyson V8 and DW battery are good but not working when pluged into this adaptor, so Im sure this adaptor is a fail !

So I purchased this because I’m on my third oem battery replacement and I hate those battery that only last 2-3 min on full ballast and now I can use my 6ah battery and I can change it when the battery runs out and that’s like 20-30 min later I’m all done with vacuuming only down side no oem charging port but that’s minimal

This works amazingly on my Dyson. I use Dewalt 20V tools all the time so I have several batteries, so I can vacuum all day if I want. My neighbors and family members are envious of me. I Love this

I love that this was an easy install and extended the run time significantly. We have 3 kids under 5 and 2 dogs, so our house is being vacuumed constantly, and this attachment has been a life saver. I do wish that the battery I have (v20 XR Lithium Ion) worked with the MAX setting on the vacuum. I only get about 2-3 seconds before it starts doing the stutter suction. Ive checked the inlet and changed the filters and still run into this problem.
