I've replaced the two lead acid house batteries with two 100 amp hour LiFePo4s.
I've changed the main power converter so that when on shore power, the LiFePo4s are charged to 14.6 volts. The solar charge regulator also charges them to 14.6 volts (given enough time and unobstructed sunlight...). But when I'm driving, the Ford chassis charging system won't bring them any higher than 13.6 to 13.8 volts.
I understand it is possible to install a device that will 'step up' the voltage from the alternator, so I get the full charge on these new batteries.
Any advice on how to achieve this will be appreciated...
