Hello All, I am thinking this may be a custom build but I will poke around for help. I need to drop the 40 volts from the main drive batteries to usable voltage for the Sabertooth 2x12a motor controller and also the EZB itself of course. Since these run power to the drive motors I need at least 15 amps of current and I would like to have a buffer up to 20 for the EZB V4, and other smaller electronics.
The main batteries are Lipo 40v
The drive motors are 18v
Then there is EZB v4
Any help is appreciated. So far I have come up with paralleling several low dropout regulators , maybe 15 or 20 together sharing a common load.
