the way how is to go to sparkfun.com where you can download schematics
and buy assembled reference designs for charging single-cell lipol
batteries, as well as the batteries themselves in a variety of sizes.
The schematic for the charger is given, and there's no circuitry
inside the batteries.  HTH.

what the?  I do not udnerstand.  yeah, if you make something yourself
in the garage, then you can still have manufacturer service, but you
are the manufacturer now so that would be self-service.  Are you
talking about your camera now or about the slog?  The idea was to have
Christopher's company put the battery into their product, so there is
still just one manufacturer and no finger-pointing: the batteries are
not yet proprietary when you buy them at sparkfun.

    dd> So I'm stuck paying for expensive proprietary batteries.

for your camera, yes, got it.

what does that have to do with suggesting a battery belongs next to
the DRAM, not external, for an internal pcie slog?  The OP was
Christopher, saying he chose a batteryless design because lipol is
among other things ``proprietary'', yet experimenters and cheap
consumer electronics have been using it for almost a decade, and there
are cheapo charging chips from linear devices or microchip or whatever
that include experience-tested protocols for avoiding flames (yes
agreed writing your own charging software would be risky), and chinese
oem may well just design it for you.  I mean srsly I have friends
using these batteries and could probably put the battery on myself so
what sort of person am I paying to make this thing for me if
li-ion/lipol is this great scary proprietary deep-FUDpool mystery to
them?  so...you know...give us a real reason plz, not a
punt-and-blame-the-sysadmin design with no battery, thanks.
