Hello Everyone,

I'm building a portable device that runs of 3.3V. I'm planning to use this battery http://uk.farnell.com/gp-batteries/nta2710/battery-li-ion-3-7v-4400mah-1s1p/dp/1848660 

I need a battery charger, battery guage and battery protection.

1st question: Are the below choices good or do you have better recommendations ?

Battery Charger: http://www.ti.com/product/bq24032a 

Battery Protection: http://www.ti.com/product/bq24314 

Battery Guage: http://www.ti.com/product/bq27510-g2 

2nd question: How to connect this Battery Guage bq27510-g2 to the battery when the battery hasn't got a thermistor lead ?

3rd question: How to connect the battery charger, battery protection, battery guage and the battery together ? i.e. what comes before what ?

Thank you so much for your time, please help me, I'm building a project that will help so many people.

    Those are fine parts, but more detail on what you want to accomplish needed to pick specific parts.

    bq24040 is a simple charger, bq24072 and bq24032a are power path parts.  Not sure you need bq24314.

    You need to post any gas gauge questions is their forum.
