if you need more than 2.5A use a second L200.
R1 = 0k75
R2 = R1*((13.7V/2.75V)-1)
R3 = R1*(14.7V-13.7V)/(R2*I)
R4 = 0.45V/ I
(X)= lamp 15V 50mA (error) or 0k24
p.s. if someone needs an +12 -> -13.8V PB charger i can give an upgradeinfo
for the voltcraft DC/DC-unicharger. it's changing a single resistor !
