I know I should probably be able figure this out by myself at this point, but somehow I can't see it.

I have a customer that wants a saber to have in his office that could be on for a good portion of the day run off the wall current, but be able to take it down and use when desired.

With the rechargeable battery pack, a recharge port, and a smart charger could you just run it plugged in for an extended time? No board, just resistored LED...
