[...] Notice that it remains above 3.4 V until it produces 1.1 A·h at 500 mA, which is roughly its rated capacity. The other traces come from those crap eBay NB-5L batteries. [...]

Thanks… it’s good to know I’m not completely off-base!

Since this post went up, one battery has completely died. The others seem to be limping along, although I haven’t run any tests. I carry one battery in the camera and one in the pouch, because there isn’t much time between the low battery warning and the blackout. I bring all the batteries and the charger on long trips!

Ed, I’m a Li-ion battery pro with 20 years of R&D experience under my belt, and I have to say–your measurements, terminology, conclusions and charts are GOOD! :-)

I’d say MOST of it is junk science and scam.
Too many DMM’s and too few ‘Scopes :D

Thanx for the Ardy Stuff!

Good Luck with the Li-Ions, I will stay tuned for a good solution.

any personal experience with free energy experiments?

Nope, because all that stuff lies somewhere along the axis between junk science and scam. The burden of proof isn't on me to show it doesn't work, it's on them to show that it does. So far, nobody's demonstrated anything better than measurement error combined with gullibility.

experience with Arduino or PIC MCU coding?

Just click on the Arduino tag over there on the right, down near the bottom I've written enough PIC assembler to desire never to do that again. They're the cheapest 6- and 8-pin micros around, but ...

hmmm Not surprised.
Using the same technology, but self built, I had little
luck with Li-Ions myself. Kinda glad I never sprung
for the big bad $300+ unit and just self-monitored
my charger. I never read where these units were
compatible with Li-Ion anyway, just everything else.

Ed, do you have any personal experience with free energy experiments?

Also unrelated, do you have experience with Arduino or PIC MCU coding?

how a Renaissance Charge system would work

Poorly, from what I read.

They use the term “open source” in a manner I had not previously encountered: long on promised unicorns and short on actual information.
