Purchased a GR Plus package 12 days ago. It took about 10 days to get to me. So easy to install! Was amazed! Installed in about 2 hours in a club car precedent. Just trimmed down the battery compartment to create the perfect level space using an oscillating tool. Plastic just cut like butter. Literally it was plug and play. Red to red. Black to black, and I was cruising that afternoon. Used 3/8” x 2.25 hex bolts with nylon nuts and fender and lock washers to mount. Played 20 holes of golf on a super hilly course used less than 12% of the battery! I live in the mountains. The cart kept speed even on my significant all uphill 1/2 mile drive home. I installed everything in the battery compartment so I wouldn’t have to rip stuff up to mount the screen on my dash. Just didn’t see the point. Highly recommend comparing with some of the US brands which cost over a thousand more. I still need to clean up the wiring but all in good time.
