Isn't it unusual to have a 2S 7.4 LiPo without a balance charger connector? This is the battery out of a toy grade Mebo robot someone gave me. Just has pos/neg to a proprietary connector. I don't have the charger.
"When you make a thing, a thing that is new, it is so complicated making it that it is bound to be ugly. But those that make it after you, they don’t have to worry about making it. And they can make it pretty, and so everybody can like it when others make it after you."
- Pablo Picasso
