Hi, thanks for responds. I got a different solution. I have found a very similar connector. Dimensions are the same, same terminals, but they are offset. So I ordered 4 pairs of this connectors on eBay for $4. Removed terminals out and put them into the purchased connectors. I used them everywhere including a charger. Made a bridge for a parallel connection for two batteries and now it is working as a charm.
