i'm happy with my WFCO 68100, without going thru all the testing some of you guys have
(although i appreciate the effort and knowledge)
i guess if i only had one hour per day to run my generator i would want that extra 5 amp hrs
but the reality of multiple run hours per day plus the solar , for me means that a few amps less and a tapering of amps as the voltage rises is really a non issue
i'm out here full time, i can't peform tests for 'data' sake
and since i recharge daily, my generator time is reflected/controlled by what else is on my schedule
