I want to hook up a dewlap 20 volt leaf blower to a 24 volt aircraft battery and strap it to a helicopter to distribute mosquito larvicide

Anybody want to make some money making this happen? Can it be done? From what I’ve read, I think there might be some minds on here that can get this done. Anybody? Thanks, Brian

damn auto correct … dewalt, not dewlap.

This is certainly an oddball request…

The voltages aren’t directly compatible. A 20V Max tool expects up to about 21V - it’s a 5S pack, 4.2V fully charged, so 21V, down to about 15V or so when discharged. An aircraft 24V system will be typically running 28-30V when operating, and that’s a good margin beyond what the tool is designed to deal with.

You’ll need to put a buck converter between them, of a suitable rating, then work out the details of running the DeWalt tool on the other power supply. I expect you’d be best off grabbing a board out of a dead battery, hooking your buck converter up to that, and (if needed) making a resistor chain for the intermediate voltages, but I’ve not tried this. I don’t think the tool will run just hooking positive and negative up.
