Marine: two batteries, two power sources, two charge directions

Hi- I added a Sterling Altprotect device, which just provides protection to the diodes in the event of an overvoltage. I did this because I have an externally regulated alternator with a remote sense wire. If the sense wire becomes disconnected the diodes in the alternator die. I probably do not need them. In answer to your other question: any charger with Constant Current/Constant Voltage capability will work if voltage and current are programmable and you are using LiFePO4 drop-in batteries with internal BMS.
