Last night, I tested different resistor values along with this 4700uF capacitor - I got for my Grid Tie Inverter repair previously - and found that the simple economizer described in this DIY Electric Car thread
seems to work . I could not find a resistor that works so I used this air dryer resistive wire again - alreday used on my mini bottom balancer - and cut a piece that was 10Ohms;

Closing the circuit bypassing the economizer, the relay closes and is using 3,5A
With the economizer, the contactor is closing and only 1A is going through the circuit - instead of 3,5A with no economizer -
1A at 12V = 12W
I will have to try with 20Ohms and see if what it does ... The idea is to leave the relay closed using minimum current, thus minimum power
