My Multiplus is limited to 13.39 volts while in Bulk and Amps are limited to around 14 or so with the batteries at 85% charge. I just started the multiplus so it has not been in Bulk but just a few minutes. It did go to 115 amps current for a short time then cut back to the 14 or so quickly.
I have 500 Ah LiFePo4 batteries and the the multiplus is set to 14.5 volts Absorption and 13.6 volts float. It is set to 30 amp input current and 120 amp charge current. I used the Victron Connect app to program which I don't believe has an assistant option to check.
Why is Bulk voltage lower than Float voltage? This is barley the resting voltage of the batteries.
