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 ideally wanted to use this with the maximum suction function but the light turns red after a few seconds. On the lower setting it works fine. Buy this if you dont mind the lower setting.

My Dyson vacuum works better with this adapter and a Dewalt battery. Much better than the original battery. Go figure with the cost of a Dyson!

I assume that there is a high voltage cutoff built in to the Dyson vacuum. I used a brand new Dewalt battery that was fully charged. I suspected that a fully charge battery was causing the vacuum to cycle on and off as part of its over-voltage circuitry so I ran the battery in a drill for 20 seconds and then tried again and voila! Super powerful and lasts for a long time.

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.

Works with Dewalt 2Ah Max and 1.7 Ah Powerstack but vacuum pulses on and off with 5Ah Powerstack. Disappointed that it can’t be used with a higher capacity battery.

Installation was easy and I have 2 fully charged batteries, but the Dyson vac only runs 5 seconds and then I have to remove and replace the battery like it is being reset. Same result with both batteries. Restarts and runs another 5 seconds. Any suggestions?

Just as bad as the original battery. Freak batter would be fully charged and not last long enough to clean the first floor

Perfect works great

Did not work at first. Finally got it to work. Stopped working at all after the third use.

Tried multiple batteries - no luck. Inconsistent or pulsing suction. Skip it.
