I've often wondered this and was curious if anyone has an updated answer.
I've seen some 3400 Panasonics on eBay that have been packaged with protection circuits and sold as having Seiko chips. I've got AW cells, Redilast cells, Keeppower cells, and I have some 3400s that claim to use 2 (two) MOSFETs rather than one.
What's the latest on current-day protection circuits? Are they all pretty much the same nowadays? How can I identify a good one?
For the record:
1. I looked at BatteryUniversity's page on protection circuits and it doesn't have any dissections or analyses of them and the like.
2. I revisted Craig's AW vs. Redilast vs. Trustfire thread
3. I revisted HKJ's dissection too
