This review is not about the actual product but the interaction. I purchased these for a golf cart as they are listed. I could only get 3 and was going to buy the other three at a later time. I reached out to the support because I seen that they want the batteries to be within 6 months. They responded and we have a few messages back and fourth and I told him I was going to make it 72v in the future. Later he responded that I can not do that and 48v is the max. I asked if I could cancel the order since it will not work for me. He answered back positively and said let me check on this for you and took my order number. I waited for his follow up and didn’t get one. A couple days later the item came so I don’t think he wanted to actually cancel my order so he just didn’t respond. Now they are in my living room in the original box unopened waiting on my like I was waiting on a response from them. Even if he was gonna say no, he should have atleast communicated it.
