Ryobi Dual Battery Mount

thingiverse

I mounted two Ryobi batteries together so that they could be wired in series, allowing me to power an old 36V mower that had a battery failure and was no longer available for purchase. The mower shown is an Earthwise 20" Cordless 36 V Electric Lawn Mower (Model 60236). Although I didn't thoroughly test it, the mower maintained full speed while cutting through some tall weeds. This project builds upon the original design of {Battery Holder for Ryobi 18V battery by Walpeup}. I duplicated and rotated the battery base from the original Thing, adding extra material to keep them securely together. The same process was done with the battery tops, along with an additional piece to hold them in place. To simplify the design, I eliminated the zip tie mounts and instead used spots of super glue (Gorilla Super Glue Gel, http://a.co/h985UHS) to secure the tops to their respective mounts. Like the original Thing, I utilized AAA negative battery contacts, which I purchased as part number BK-204 (Digi-Key Part Number BK-204-ND, https://www.digikey.com/short/j9728p). To attach the battery holder to the mower, I drilled small holes and screwed it in place using washers to distribute the weight evenly across the plastic.
