This is a working Lester Summit II charger for electric golf carts. It has the crow's foot male charging plug (see picture). It was used for a Yamaha G16E (which is a 36 volt golf cart) but the device will also deliver 48 volts. You can download the companion app for "smart" charging features. I used it for lead acid batteries.https://www.golfcartgarage.com/club-car-yamaha-ezgo-36-48-volt-golf-cart-charger-lester-summit-ii/
