Model: Fit for DeWalt Battery
This is a 3d printed adapter, but it is well done and feels very durable. The connectors appear to be embedded in an injection molded pieces so there's no chance they will move around. The DeWalt battery fits well into the housing which is the part that you will generally move. A whole pack of fuses were included for convenience. They are just automotive fuses so you can replace them with any standard ones. I tested the output from the battery, and it appears to be straight battery voltage out to the pins. You can use this for a variety of projects, but it's designed to be a seamless fit with the eDrive. There's no battery protection in Dewalt batteries so make sure to remove it after each use to prevent over discharge. That's not a fault of this adapter just the reality of Dewalt batteries.

Model: Fit for MilWaukee Battery
I bought this Milwaukee battery adapter for StacicC electric bikes for my grandkids and it works good on the 16. But a tight squeeze on the 12 with the adapter and battery but I thought it may be a stretch when I got it and I have lots of Milwaukee Batteries and the smaller ones like 2.0 and 3.0 amp work a lot easier than the bigger batteries and for the price it’s a good value

Model: Fit for MilWaukee Battery
This battery adapter is clearly 3D printed, but appears to be of good quality overall. It fits the bike securely and has nice large terminals for connecting the battery. There appears to be a removable plate on back for accessing the internal electronics, if needed, and it comes with lots of spare fuses. Very easy and quick to install. Makes swapping between stock and aftermarket batteries easy, ensuring long battery life. In my experience, the Milwaukee batteries are the best aftermarket alternative for the Stacyc due to their built-in discharge protection. This adapter should retain that functionality. Price-wise, this is on par with other adapters of this type, but as long as it works well and lasts, it is a good value overall.

Model: Fit for MilWaukee Battery
The media could not be loaded. If you have a Stacyc, this is a killer adapter! Don’t worry about replacing the overpriced Stacyc battery, get this adapter instead! The adapter slides directly into the battery slot on the Stacyc without any issue at all—easiest install EVER. Then, slide your Milwaukee battery into the adapter, and POW… your kid is ripping and riding right away! The adapter does not take away from the power or speed of the bike, and instead works as well if not better than the original battery. The battery life is as good as your battery as the adapter doesn’t take any power away from it. Overall, this is a great fit for a replacement and something I would recommend and share with others! One note, on the 12 inch bike, the 3amp hour battery fit fine, but the larger batteries may not clear the tire. Check out the video!

Model: Fit for DeWalt Battery
Works as expected the dewalt battery fits and locks in great. The esthetics are really nice. Clean lines and clean finish. The battery tabs male and female are substantial and high quality. Includes 10k ohm resistor to "trick" the stacyc to use a different battery. The only area I could see for improvement which I pictured. Is on the bottom it doesnt tightly close off access to the terminals allowing dirt and debris in. Not a deal breaker but a note. The flip side of that is that gives a little more clearance. In the pictures I compared it next to a 3d printed model I use. Both are great options this one works well and like I mentioned has really thick strong battery terminals. It installs pretty easy. Depending on the battery size you have. You will likely need to install the battery into the adapter then the adapter on the bike. So to change the battery you will need to remove the adapter.

The media could not be loaded. It feels made of good quality plastic. It’s 3D printed. Worked right away. the milwalkee batteries are very large and there is enough clearance between the battery and tire tread. Came with ten 40amp fuses.

This adapter kit functions as intended and gets the job done, though there’s nothing particularly special about it. Kind pricy for what it is.
