I used thyristor from Russia, it's KY202G, I don't know the characteristics of it
but it works fine...
KT708 is tryied first and it works fine to,
but I had to use KT708 somewhere else.

Some components on PCB, it's BRX49

Some markings on PCB for AC input ,battery , and a potentiometer RV1, 470 Ohm/1W that I
never use.

This pot I use, It's for setting the charging current and a voltage that I want to battery
to go to. If the battery is empty, and I want to have a controll of the starting current I turn the pot on left side to lower the wanted voltage,witch in turn will lower the charging current.
Mostly,my pot is in the middle, the resistor restricts the amp flow to a max 6A, so I don't have to worry about anything.
