BQ35100: Programming chemistry for unlisted battery and using large shunt

Part Number: BQ35100

Hi, 

I'm currently developing a small primary battery board for wireless node. During active mode, the wireless node draws approx. 5-10mA from the primary battery. The primary battery is Tadiran TLH-2450 (550mAh) which is not on the list of chemistries in the bqStudio.

In order to measure the relatively small current, I'm using a 2.2Ohm resistor. But I couldn't calibrate this value into the device using the bqStudio. I also tried to calibrate the device by drawing 3mA via the shunt. However, the bqStudio alerted that the typical calibration value is 1000mA. 

Another question is whether there is a way to create a chemistry file for the TLH-2450. I did look at the GPC. However, I was not sure whether it's compatible with primary relatively low current batteries.

I would prefer to use it in EOS mode.

Thanks,

Shlomo
