How does the 36V transformer change the starting power of the car?
With a 20 "2" tube, add a heat sink, just one end of the 2 pole to connect 24 volts one end, and then use a multimeter to measure positive and negative poles, and then connect it to the corresponding positive and negative poles of the battery
Then the electricity for clamp meter to measure the current, if the battery is charged with a current of 100 ampere 10 or so, if the current is large the 220 volt power supply terminal receives 380 volts, then 220 volt power supply, current will drop, anyway, this transformer can meet your needs. Adjust the voltage until satisfied.
