Re. RE. fake batteries
Hi, I've also had this problem.
I bought a T68I "Genuine Replacement" that actually had a Li-Ion coin cell badly soldered in place, instead of the expected LiPo, good thing I took it apart to check why the capacity sucked.
It even showed up on my phone as genuine, apparently the scammers "recycle" dead cells this way by the thousand to work around smart batteries.
Since then I've been sent numerous pictures of "genuine" batteries with everything from bits of lead (byebye RoHS) to old screws inside to disguise the poor quality parts used.
The scumbag faking scum are even using ultrasonic welders to put genuine cases (recycled obviously) on fake cells, and even going as far as labelling them NiMH on the Customs forms to get around the lithium restrictions.. !!!!!
If you don't believe me google it, there are lots of deathtrap electric drill batteries around using recycled laptop packs where the one bad cell is simply removed and the completed stack soldered up and repackaged with genuine PCB and a genuine case.
Needless to say, the e-bike users are also feeling the pain from this, as a lot of the more expensive bikes need the exact pack to work so rebuilds are commonplace.
I am thinking about starting a counterfeit battery analysis and testing company as this could help a lot of people get their money back in a way similar to h2testw for fake memory cards..
