Battery recharger schmatics sought
 

Greetings:

I am interested in finding a source for schematics and/or a kit for
constructing a battery recharing unit.

I'm new to "homebrew". So kits and/or schematics with explicit
directions is appreciated.

The battery pack I am looking to recharge is a collection of approx 40
1.5v NiMH cells for about 28V overall. In fact, any
kits/plans/suggestion on making the battery pack itself would also be
appreciated.


Thanks!!
