I was looking at building one too. I really would like to know exactly which component shuts the charger off when the batter is fully charged. It seems that no one can really tell me so I bought a smart charger and tore it apart. It looks rather siomple but when I figure it out I'll let you know. In the mean time here's the one I bought which seems like it might suit your purpose.

You can just always trickle charge it, but that isn't very efficient.

I can't think of anything with something adaptable in it.

You can't care for the battery properly without a proper charger.
