I have a RS Reefer 250 being delivered this Thursday and was torn between the MP40 and the Nero 5. I finally selected the Nero 5 because I didn’t like the appearance of the wire mounted on the outside of the glass on the MP40 and also the Nero 5 had a smaller profile mounted inside the tank. However one concern I have is the fact that they don’t sell a battery backup for the Nero 5 like you can get for the MP40. I live in a condo in Florida and have experienced some blackouts in the past from FPL (not just from a hurricane) so I definitely need something compact, any suggestions? Is it possible that AquaIllumination is planning to release a battery backup in the near future?
