That sensor input could be the output from the auxiliary device ... the auxiliary device itself monitors each individual cells temperature with it's own temperature sensors ... one on each cell ... the auxiliary device then changes the signal to the Super Brain when it determines the temperatures are at some point you design it to look for as a trigger.
That trigger point could be a specific temperature ... or you could be looking for the dT/dt type effects... whatever you choose it to be in the design ... if you wanted to get fancy in the design you could make it changeable ... either directly or by connecting it to a PC.
That is what I was referring to by the external circuit.
Now weather it is worth the effort or not ... that depends ... but it is doable.

That is the key. It isn't even worth pulling the sticks out of the pack for us. We keep them in so that we can run a fan. The extra labor it would entail is daunting. Then there's the issue of Toyota Prismatic cells. You have to keep them in compression, so where would you attach the sensors?
