I Put a 48V Lithium Battery on a 36V Golf Cart Motor… Here’s What Happened#golfcart #lithiumbattery

In this video, I install a 48V lithium upgrade using a DC House 51.2V battery and a Navitas 600 amp controller — while still running the STOCK 36V motor. ⚡ The results surprised me: the cart hit 22 MPH, and I walk you through exactly how I wired everything step by step. Stay until the end for the full hookup and lessons learned. This is part of an ongoing golf cart build series. More upgrades are coming soon — suspension is likely next. 👀 👍 If this video helps you, please LIKE, SUBSCRIBE, and FOLLOW the build. #48vconversion #dcHouse #golfcartbuild #ezgo #diyelectric #golfcartmods ⚠️ Disclaimer: Some of the links below are Amazon affiliate links.
