ante Posted July 1, 2005 Report Share Posted July 1, 2005 Hi Bob,Welcome to our forum.If you got DC output you need a switched DC/DC converter or you will get heat losses. Try to find one ready built, they are not easy to construct from scratch when 40 A is involved. You might find one that they use for electric forklifts they sometimes have an adjustable output 12 – 14.5 V. Electric forklifts with 48V battery have converters which runs at 32 to 60 Volts input. What’s the size of your 12V battery (Ah)? Quote Link to comment Share on other sites More sharing options...
