Odd BB400 behavior

[pedalinbob]

I have 2 BB400's that i placed lux3's on. not sure of the bins, but one is more white/slightly blue, the other warmer, slightly tellow.

i had noticed that one of them (slightly yellow) appeared dimmer than the other. lux readings showed 230, which is about 200 lux lower than normal.

i checked the bats, and they were 1.24v and 1.23v, total 2.47v.

so i threw some new bats in (1.62v x2) and voila! 440 lux.

this seems odd, because i thought the BB400 dropped out of regulation at ~1.6v?

maybe a cell is goofed or something...

the cell voltage will sag under load.

thank you CNC, i knew i was missing something.

wow, i did not realize that the bats would sag by 0.8v.

would lithiums sag that far?
