They are expensive, but i really like my Noco Genuis 2440. (40 amp)
I think the victron ones are great but they are limited in amperage output. To get something over 25amps your choices are Aims, Iota DLS (probably not waterproof), or the NOCO.
I like aims stuff, but yes i believe they had a bad batch maybe a year ago, several failures in a short amount of time from what I understand. I installed one a few months back for a guy, works as advertised so far.
