: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.

Oh well, you can't have what you want without some cost, can you? :)

Re: Lead acid charger circuit with float

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.
