Must get the CN3083 datasheet from seeed as the manufacturer didn't
bother to put it up.
NO DATASHEET for its AIC1896

Lipo rider pro: CN3065, Intersil ISL97516 DC/DC

I wouldn't touch anything without datasheets, and I've gone off seeed a
bit because their schematics are pretty unusable and their designs not
always so good.

Given the functionality in a LiPo charge IC it would be bad ecnomics
(time + money) to attempt to re-create that with a microcontroller and
associated analog lafaffel. They don't have discharge protection though,
which looks to me like a pretty significant oversight.

And 6Ah too...

An intersting rundown of batteries and chargers is
http://www.torchythebatteryboy.com/p/18650-batteries-chargers.html
and the rest of the site is an interesting read.

Does anyone have a confirmed source of non-cr*ppy 18650?
