Hi experts,
Need some of your expert advice. I’ve got a rover that is powered by two lipos currently. 3S lipo for the FPV (Camera and Transmitter) and 4S lipo for the rest of the electronics. Ive got a remove which I control the rover with and it has an LCD to display various information. A crucial piece of information I want to display is the rover battery fuel gauge. If possible for both the batteries.
I have been looking at off-the-shelf fuel gauge IC technologies such as MAXIM DS2788 however they are in SMT form factor and it doesnt help with quick prototyping. All I need to see on the display is a VERY good ESTIMATE of how much voltage is left in the batteries (individual cell voltages are preferred) so I know its close to charge. Because lipos can be a pain to maintain if they are discharged below a certain voltage.
All suggestions are welcome. Thanks in advance.
