I am looking for Lipo charger that can work from a 18V DC supply and charge a 4cell Lipo.

I want something that is cheap and small. It doesn't need to be a balance charger.

Schematic, kit, or pre-built PCB would be fine.

I am thinking of building something based on the Linear Tech LT1571, but I thought I would check and see if someone else had done the work for me. :)

LT1571 datasheet:

Thanks!
