1. This is off the shelf hardware. Easier to buy than to make. Any 'battery tender will do ya - about $10.
2. There's a whole lot of knowledge embedded into modern microprocessor-controlled battery chargers, even simple ones. There's no way an individual can replicate that. I've built lots of homebrew electronics in my time, but I can recognize when it's not worth the effort, or even when no amount of my effort in my lifetime will do as well as what I can buy, probably for less than the cost of replacing the battery after one goof fries it.
