My kids have a Peg Perego John Deere Gator tractor that uses a 12v battery.
https://www.amazon.com/dp/B000G0KT6Y/?tag=pfamazon01-20
The battery requires monthly charging or it will die. The charge is slow and the winter months are a hassle. I could replace the battery but I'd rather convert it to run on my 18v Makita LXT Lithium Ion batteries.
My tenative plan is to "gut" a Makita LXT flashlight to use the base to clip the battery in, then mod the flashlight base either into the old battery housing or simply with the old battery's pigtail on it. Inside I'd like to have some kind of voltage regulator or other means to convert the 18v output from the battery into 12v for the tractor motor.
The standard battery is a 12v 7Ah lead acid battery and cross references to an Interstate SLA3041

The Makita batteries I want to use are 18v 3Ah Lithium Ion model BL1830

I found this DC-DC converter online, but it is expensive and I don't know if it will work: http://www.newark.com/jsp/search/productdetail.jsp?SKU=71K9635&CMP=AFC-TL10000001
This project was inspired by this video from DPX systems who made a mini bike that runs on a Dewalt 18v drill.

Is what I'm trying to do feasible?
