Probably the best dollar value for putting amps into a Victron LiFePo4 battery. It doesn't have a remote shut off to allow it to be controlled by a BMS, so it pairs well with something that has remote off switch like the BMS 12/200 or Cyrix-Li. I bought this instead of the Phoenix charger because it was nearly half the price and I didn't need the extra features of the Phoenix because I had the BMS 12/200. I like that it's bluetooth and shows up on the Victron connect app.
The heat control is good on the Blue Smart because it has a fan whereas my DC|DC converter gets smoking hot because it's passively cooled.
Fully recommend.
