Hi, I'm replacing the T-875 battery pack in a golf cart with a 48V Dakota Lithium LiFePO4 battery. I also ordered their 15A charger to make sure it would play nice with the builtin BMS. I was very frustrated and disappointed to discover that this charger puts a continuous 0.12A drain on the battery when the charger is not plugged in. This golf cart is sometimes parked for a few months during the winter and I don't want the charger running the battery flat. I'm also trying to make this as user friendly as possible since the T-875 pack didn't last very long due to no care of the pack.
I first thought that I could install a NO relay with an AC coil which would close when the AC cord was plugged in and so ordered one. Then I thought I better see if there is any arcing when connecting the charger to the battery pack. Yep. There is a nice pop when connecting the charger so a relay/contactor would not last very long with that. So I decided to find a diode which I could use but I'm not having luck in finding something since I don't know exactly what parameters I need to search with. Does anyone with more EE knowledge than me have a recommendation? I do have room just above the motor area and beside the controller to mount something to the frame. A recommended heatsink, if needed, would be helpful, too. Thank you, David D.
