bq40z50 and bq40z60 reference design for LiFePo4 in 2S config

Hi,

I have a customer looking for a reference design for either bq40z50 or bq40z60 configured for 2S batteries. 

I've checked on TI and there is a bq40z60 for Li-Ion. Could anyone let me know if the reference design could be used LiFePo4? (I suspect it can).

If so, is there test data showing it in a 2S config.

Best Regards,

Wally
