Unfortunately, you can't just go with an average, you need to know if
any of the six thermistors triggers.
We looked into adapting the PTC circuit, but it was not sensitive enough. Its' basic settings are normal, normal, normal, about to catch fire.

If you don't sell them anymore than that is no longer an option for people... oh well.

As of yesterday, there were two available in junkyards in all of North America (well the US and Canada). The recovery rate for sticks has dropped to an average of 5-10 per "good" pack.
Our recovery rate for trade-in packs is more like 1-2 sticks per pack, but that's heavily weighted by Civic owners who get an IMA light and do nothing about it until the next year's inspection comes. At least most Insight owners take action while the battery is still salvageable.

A mixed pack wouldn't last a month. The SOC of the sticks would soon be very different between the old and new sticks. There's nothing wrong with either one, it would just be like putting studded snows on one side of your car and cheater slicks on the other and then trying to run a rally race in the rain.
