I use the Unisen-E with the Frsky lipo sensor. I like being able to compare my SuperX, Taranis, and Icharger logs, gives a nice picture of whats going on over time with my lipos.
If I used voltage only, at 3.6 volts I'd be way past the 80% mark. Generally my lowest cell is at 3.68-3.70 when I hit max MAH at an 18 amp draw. So 3.6 for me would probably put me at around 10% capacity left, or lower.
You can now run 2 lipo sensors with the latest versions of OpenTX firmware. Picked up that bit of info it about a month ago over in the taranis thread.
Just an example of what the 10ah10C is capable of at current IR readings.

Alot have been saying that the Multistars probably can't deliver the goods. Mine does, tests out at 14.1C.
Means it can deliver 141 amps without damage.:tennis:
Picked up an Icharger.
IR readings 10AH4S Multistar 10C.
Continuous current [A]: 141.4
voltage drop per cell [V]: 0.424 total voltage drop [V]: 1.697
Continuous C rating: 14.1C
