Hi,

I use lithium-ion USB based battery packs for my beaglebone projects. I am keen on developing the charging system myself.

I know the battery inside is 3.7 V, so how does the pack derive 5 V from this ?? Also how is battery temperature monitored ??

thanks
a

Consider a boost converter and temperature sensor.
