Boondocker BD-1275-C battery charger

Well the Boondocker BD-1275-C 75 amp battery charger I installed for our batteries worked great, after 2 days and nights I fired up the generator and plugged the Boondocker into it and according to the Trimetric monitor I installed it jumped right to 57+ amps,  which is way battery then the 30 amp car battery charger that I was using and way better then the stock converter would do. It cut way down on the charging time.
