    FLA is the most forgiving of temps and ignorance. Sealed lead batteries are expensive and shorter lived than their flooded brothers. Li will reward you in cold temps, by shutting down, unless you keep them heated. Ignorance with them is rewarded with smoke. NiFe is awfully forgiving - but expensive.

        I like NiFe and could see myself shelling out the money, except it has a really poor charge/discharge rate. From what I can see, it's hard to run high-amp stuff for short bursts, and even harder to charge the things on the 4 hours of sunlight I get. Currently, I'm thinking maybe LiFePo4.

            Eric, On your test diagram, you show the input in Amps from the 2 chargers. Note that the two together (46 and 14) add up to about 60A of charge. You are using a 6500 watt genny. 6500W / 110V = 59Amps. it is not possible to get 110 amps out of two 55 amp chargers when the max the genny can produce is 59A. It appears to me that you are getting the max out of the two chargers. I know I'm a little late with the comment here, but I hope you got your problem solved.
            It would be great to hear how you solved the issue.
