RE: Adapting cell battery to HP 41
That is a very nice setup you have there TW!

The 41c solution needs a dc-dc boost circuit in order to use lithium ion batteries. Hmm, a fresh set of 4 N cells starts at around 6.4 volts output, maybe two LiFePO4 cells, if they made them small enough, would do the trick for a 41c.

CC41 coming soon!
