If you use DeWalt 20V power tools you already have the perfect battery to power your Sullivan Dynatron starter.  The DeWalt batteries are 5s2p LiIon batteries with built in protection circuits for overcurrent and overdischarge.  The Dynatron will turn over a 1.20 nitro engine with ease on the DeWalt LiIon batteries.

This 3D printed adapter mounts to the Dynatron motor and provides an easy way to use your DeWalt batteries for a convenient starter setup.  It balances well in the hand and doesn't add a ton of bulk to your starter (depending on the battery size you use).  Comes partially assembled and pre-wired.  Wago 221-412 wire splicing terminals make it easy to connect your Dynatron's input leads to the adapter and get flying with no soldering required.

The adapter pieces also have holes into which you can put the disassembled Sullivan wand, to save on travel space.  Other wands between 7-8mm in diameter will fit, though not all will reach into the rear retainer.

This product includes:
1 x 3D Printed Sullivan Dynatron DeWalt 20V Battery Mount Set (Black ABS Plastic)
1 x Injection Molded DeWalt Battery Terminal
1 x Set of Power Cables (Can be shortened as needed, preinstalled)

This product has a limited lifetime warranty.  If the 3D printed pieces break due to impact damage, let us know and we'll get a new one sent out to you.  The warranty does not cover melted or damaged wiring or terminal due to extended periods of too high amp draw (e.g. stalling the starter motor for too long).  

DeWalt Battery, Charger, and Dynatron not included. 

Shipping Disclaimer:
In an effort to reduce waste of shipping supplies, if you order only a starter adapter, it will ship in the single box that it is packaged in instead of being double boxed.  Any additional small items ordered, if they can fit into the adapter box itself that is how it will ship.  If your order is too much to fit into the starter adapter box, then it will be double boxed.

DeWalt 20V Battery Adapter

I love this setup everything assembled perfectly. It was pretty easy to setup. I’m definitely ordering another one just to have a spare. Thanks KC3D well done 😊

Best investment I’ve remade since getting back in the hobby. Quality is superb! Also, it shipped out quick despite being out of stock. Thanks again!!

Great fit and quality!

Bought this for my father since he had the dewalt 20v tools already and this worked great on his Sullivan starter. Thanks a lot!


Great build quality


It’s perfect, finally stop using a battery box and use my drill battery! Fit and finish is perfect and would recommend to anyone! Don’t know why I didn’t do this sooner!
