John, a question. What's the date on your test reports / files?
I don't remember the details any more, but I hit something similar many
years ago. So I paid to have the files refreshed to solve the issue. It was
a minimal cost.

Hello all,
I'm having a bit of bother with Amazon.com at the moment. For a small
rechargeable battery-containing product they are requiring one of the following
in order for them to sell the product on their Canadian platform:
* CAN/CSA C22.2 No. 62133-2:20;
* IEC 62133:2012 or IEC
Hi,
We’re looking for a battery safety expert to join us on a project. They need
to be very current on high performance lithium-ion packs as the current best
practices lead the standards a bit.
Please contact me directly.
Best Regards,

I've seen this resistor used for the low battery alarm circuit. It keeps the
battery voltage from rising as load is shed and confusing the low battery alarm
circuit. There is no safety reason that I know of. 91K ohm is an odd value
though, left overs from another product? I'm assuming that the
