I have some 24v victron smart lifepo4 batteries to connect in series, i see in the manual it states they should be charged to 28.4 for volts for several hours just wondering how people are doing this? I have various chargers but i dont think i have one with a settable output voltage unless it has cell info e.g i have junsi smart chargers where it would need to see all the individual cell voltages i dont think this will be possible with victrons batteries. Any tips? Thanks Jack
