:Any one have a suitable for a couple of large car battery from my toys
:(old jags) ?

:  I have a suitable centre tap transformer with around 14 16 and 18v ac

:available at 8 amps or so


There are a number of battery charger designs suitable for a vehicle battery,
but you don't need anything fancy. I reckon an SCR controlled unit is an ideal
choice and here is one example which seems to be workable.

You can actually. Save your transformer and get a busted salt-water
chlorinator unit from a pool shop (check the pile out the back:-).
It'll have a transformer capable of 15-20 amps, and probably a bridge
rectifier for you. Pool shops ditch these all the time after the control
circuits blow.
