Vitronic is UAE OEM buyer for Electrovaya portable battery box for their Poliscan radar, hope they are not in Battery Japan to identify new battery supplier :-(

They completed order in Q2 2014 (January to March 2014) and always mention that "The OEM is expected to continue purchasing larger quantities of these portable systems" but no news of new order since delivery around 1 years ago ...
