charge from dynamo
I want to charge from dynamo (bycycle dynamo 12 volt) with emergency light 6 voft 4.5 ah. (builtin charger).
Please help me.

The charging control depends on the type of cell but, as you say it has a built in charger, it should take care of all that. It seems to me that you would need a voltage stabiliser, set to the maximum input voltage that the charger / battery needs. Then you should get some current into the battery even if the dynamo output is not its maximum. To avoid the battery discharging back through when the dynamo is not turning you will probably need a series diode, too, immediately before the battery pack.
