Put 7.2K ohm 1% 0.5W for 25.2V output.
The white 水泥電阻 5W, 0.1 ohm is current limiting resistor. PUt 3 in parallel for 3A output and 5 in parallel for 6A output.
There is a new version of SUPER car step up adapter rate at 100W.
Original Value:
Parallel Base resistor 7.5k Ohm
Volatge selector resistor: 15V Open circuit, 16V 72k, 18V 22.1k, 19V 18.6k, 20V 14.8k, 22V 10.65k,24V 8.6k?
Modified:
Parallel Base resistor 9.7k Ohm
Voltage selector resistor: Open circuit --> 12.6V, 5.8k --> 25.2V
If not change the prallel base resistor, 7.2 kohm will output 25.2V
***************
Now I made 4 chargers and take 48A altogether with the car engine & alternator running. Finish charging in 15-20 mins.
