Lipo fuel gauge

[Grumpybeard]

Hi,

At concept stage in design of RC rover with onboard rpi, where the rover will be collecting environmental measures for transmission to server for real-time analytics.

I plan to power rover and pi with LIPO packs, and wish for real-time inline monitoring of voltage remaining in supply. Is there such a plug-in solution for multi-cell packs without any need to circuit build, perhaps a meter with a data out for example, I've googled without success.

Many thanks.

there are a few available items you can use from the rc hobby area, try looking at places like hobbyking.com to see if anything fits your planned project

theres the openUPS from mini-box that might fit your needs.

That certainly looks like it will work, not cheap but no soldering skills required either, thanks!

Would that work with a hybrid solar/battery input, recharging the battery from solar?
