Tesla Switch

Four 4, 8 Volt 2000mA Nickel Cadmium batteries. Does anybody here know a safe way of initial charging those batteries from a lab power supply I do not have a NiCad charger so I need to make one. Any circuit drawings of a simple NiCad charger I will be glad to get some help on this. I have four 4, 8 Volt 2000mA Nickel Cadmium batteries.

from a lab power supply I do not have a NiCad charger so I need to make one. Any circuit drawings of a simple NiCad charger I will be glad to get some help on this. You have a minimum of 4*4. 8 V input voltage need + the required voltage drop of either the LM317 or the transistors, so you need to choose your power supply output accordingly. I think you need some heat sink on the active pass device too. Well that sure is a lot of trannies but if it works, great deal. I have finally decided to put together a relay powered one to play with. Had to pack the relays in foam to quiet them down. Was very surprised to find what I did. Using 4 4. 5 ah 12v and driving a 1amp motor, I already have 4. 5 hours run time logged and have dropped from 13v down to 12. 8. I have a switch time of around 12 a second. I am depleting the batteries but at a very slow rate. At 1 amp, I should have killed the bats by now. So to conclude, I see this upping the run effective run time for the motor. As I intend to run an electric motor to power my bike, this should give me a greater distance of travel overall. Will look into solid state relays for the switching as they will trigger on 5 v and can use a 555 to run the pulse train with. The other board still has a heat problem with transistor 6 and I cannot figure out why. I have been over the circuit many times and its wired exactly as the diagram states. The only problem is if I lose a relay, I will...
