I bought this EGO 3D printed mount on eBay (https://www.ebay.com/itm/141994625700
) and used the tabs from a EGO battery charger that I took apart to create a slim mount for my 7.5Ah battery. Unfortunately, I haven't had any luck with it since the tabs don't go far enough into the battery to get a consistent connection.
At one point, I did have my EGO battery pack on top of half of a EGO battery charger working but I wanted to slim it down further to stick in a rear rack bag along with the controller. If someone wants to go down that route, eBay usually has chargers for ~$20. The chargers are fairly easy to pull apart and remove unnecessary pieces.
@Alan B - how did the Nickel-Silver 20 gauge Sheet - 6" x 6" work (https://www.amazon.com/Integrity-Beads- ... B00JDVVYNO
) for you? Does it get too hot? How did you end up cutting the sheet?
@XanderChop - did you end up buying or making that mount? If so, how did it turn out?
