Battery charger?

Hey! I want to be able to put rechargeable batteries in my robot and then plug it into the wall to other words, I don't want to pull the batteries out to recharge them. Can anybody give me some pointers on that? 



Congrats on node 22000.

Well, I typed “battery charger” in the search box and came up with this. It can be used on-board, it will power when it charges, it has hi/low indicators and can be configured to charge just about any kinda pack.
