Interesting, is that 23A for each battery? so could I go up to 46A for the pair? I have the PL8 I've been using set to 40A, but it rarely goes above 23A unless they're very empty.

It's going to be 35°C or so in the UK for the next few days so I'll set it lower. It goes down near 20°C at night when I charge but the flat stays warmer from the day's heat.

The float voltage needs to be around 13.5V (27.0V) and it should fall to this level when, as above the current drops automatically to 0.3A.
Thanks. My 24/12V converter for my ventilator constantly draws about 0.15 amps. Should I set that value a bit higher because of that? to like 0.4A?
