BQ35100: - Possible fuel gauge solution for LS33600 @ 7.2V?

Hello,

Today's a holiday and no one is in the office. We will get back to you tomorrow.

I've downloaded BQ-Studio to see the list of supported Chem ID's, but the LS 33600 is not listed. Which chem ID would I have to use to make this work? 

Hey Billy,

Are you going to be using the EOS mode on the BQ35100?

Yes, we will be making use of EOS. We will probably experiment with the other modes a bit, but end-of-service alert is what we have in mind. 

Looking at the data-sheet it seems the max Vbat is 5.5V. How should we go about monitoring a 7.2V battery pack?  

Hello Billy,

For EOS mode it is does not matter if a ChemID is programmed. However, I was able to find your battery on the list. Did you make sure to update the Chemistry Version. 

How gauging with multiple batteries in series or high voltage, you will need to setup a resistor divider. I will share a document that talks about this. https://www.ti.com/lit/an/slua760/slua760.pdf
