Battery power consumption meter/logger (6S LiPo up to 30A)

[BMOE]

Hi.
I'm looking for a module that can measure power drawn from a LiPo battery to be able to estimate how much power is left.
As the power draw from the circuit is very uneven, only measuring the voltage is not good enough.
The LiPo battery is a 6S (21,6V) and the maximum current drawn will be 30A.
Anyone knows of a module or circuit that can do this.
It would be great if it had some type of communication interface to be able read out the data.

Thanks
/M

Hi,

you may use other phrases like "battery monitoring"...
Many big semiconductor IC manufacturer has such devices. Look at their internet sites.
Or look at a distributor internet catalogue.
