I intend to use an old petrol powered dc generator/welder for charging a24V1000Ah battery. The measured open circuit voltage on the generator is 65VDC. A DC/DC charge controller efficiently will bring this down to the required batt. charging voltage (24...29VDC). Now, here comes my question: can I use the generator as a motor to start the petrol engine with? I understand that the inrush starting current would have to be limited to some extent, as this will be provided by the juicy 24V battery.... thanks for your replies, Peter.
