I use two DPS-600PB (google it) in parallel with a digital display, total cost of $65. It's is capable of load sharing up to ~80A@(13-13.7V max which is good for F8x series) in parallel Config. It doesn't look fancy but it does the job and it was fun to mod it.

Is there an easy and safe way to increase the rated voltage from 12.15V to lets say 13.7V?

I did 3X DPS-600
  (3x47A = 141A - 12V)
13.5V = 127A
14.2V = 121A
parallel
modification of the OVP to 15V
control voltages
12.5V
13.5V
14.2V
the only difficulty is that you have to make adjustments voltage for each
power supply DPS-600
4godziny tested at 65A
Here are my programming E91 with this power supply

The second did at 80A or two DPS-600
modification of OVP to 15V
voltage regulation
12.5V
13V
13.6
14.2V
14.8V



two power supplies already have dozens of hours of work, and how far it's OK
