So what i was thinking was it must be able to measure the voltage some separate way and something is stopping the current from flowing.

Teaching the public about these components, which are not for sale, costs money and resources.

Its unreasonable to expect TI to provide tech support for something they dont sell.

Good grief. Venting out of the way, Ill be curious to hear your results.

Heat A short somewhere Since these batteries are capable of exploding, proceed with caution.

How is protecting your revenue stream a load of crap Why would anyone bother going to work each day if not to generate revenue and a paycheck And if youre complaining about TI not providing a public service, why should they Their corporate customerpartners have paid big bucks for proprietary circuitry.

Regardless, I jumped the fuse (still installed) but still the battery will not provide current.

I think they must have disabled the PCB, so even if you attach new cells, the chip will not work with them after it failed once, including blowing the fuse.

Or it must sense that the fuse is blown, seems like a controlled fuse, blowable through resistors.

To do this you need an EV2300 interface board available from TI.

You connect the interface board between your battery circuit board and your PC.

There are also lots instruction documents available from TI.

To get it to go pyro, you have to really abuse them mechanically, or overcharge them at a high current to generate enough heat.
