Well, I Just soldered two wires to conectors.
As bl50a is a small battery, I put two of them um paralelo, also soldered one to another.
Not The Best solution, but I will Not return to Ni-MH batteries any more. They get too Hot and leak.
I believe these small cell batteries are 950mAh each.

The adaptation to 67 was easier than 41, as it didn't need The step-UP converter (4v tô 6v).
For The printer and cassete, I used bigger batteries and no step-UP to, if I remember well.
