The store or neighboring store may have video surveillance, did you ask? Why did you remove the battery, it locks into the frame doesn't it?
I noticed Juiced has been out of stock on on 52V batteries for a while now. They have 1 new battery coming out, a 15Ah model, and I expect the 13Ah battery will no longer be offered, Not sure if they have any update coming for their 19Ah battery.
I suggest you call Juiced and see if they happen to have loaner or used battery they could send you until they have stock. Some companies are good about that, I think it does not hurt to ask.
What bike do you have? If you have one that used the earlier narrow battery then there are options I understand. However; since you said they were out of stock I presume you are looking for a 52V wide frame battery? I hope to test a 3rd party one soon, but probably not soon enough for you.
