Newbie Charging question
Just picked this up got it cheap as it has been sitting for many years. All batteries were left disconnected ect. I for the life of me can figure out what the piece is I need to hook this battery up to a charger? Don’t want to spend a ton of money on part just want to see if it will still work after sitting. Don’t want to upgrade to LiPo until I know it works (if it dosent I’m just going to shop for a lipo rtr)
