You could also try Nimh instead of L-ion, that would put you under 6V.
Or you could just use One Li-on Cell, saving space and not having to resistor your LED.
I would also like to thank you for "Stepping up" on these forums. You are communicating better, but still need to master the ways of search-fu. Only then will you become wise in the way of sabers...
I do need to get more search-fu.:) Thanks a lot.
in case it helps I drew up that very circuit last night
here you go, has recharge port, two li-ions, and a pcb

What do you think about this setup, with this you donīt have to use a regulator. Will that work or will I get any problems with heat? Actually I dont see the reason for using a voltage regulator? :confused: SEE ATTACHMENT --> (Or is 6V source to much for the cheap hasbro boards???)
I am not sure where you will find a 6V rechargable batt pack. Most batteries are either 3.7V (Li-Ion) or 1.2V (NiMH) You can use 4 NiMH batteries for 4.8 Volts and not even need a voltage regulator. 4.8 Volts is very close to what the econo board is designed for anyway.
You are right, I thought AAA accus have 1.5v not 1.2 ... But what if I use 4 AAA alkaline they have 1.5 so 6v is that to much for a hasbroboard?
