Yes it is easy and cheap when you are at that level with the chip devices listed earlier. That is the way the RC battery gauges are made. Nothing new there.
Indeed... most of the RC ones I use are just dumb display units... and whilst the one I use the most claims to be able to measure from 0-60v (4.5-60v without an external battery) and 0 - 180A (it was 0-100A when I got mine)... I have to think if you used it for more than 10 seconds at those sorts of loads the plastic would start dripping off!!!
Thanks for that link... they look much nicer and should be just a bit more accurate than the usual dodgy eBay options!!! :-D
Yes, if you can track voltage and current well, and have also set the battery capacity, then it becomes a very nice battery state-of-charge system. Hm... there must be some temperature sensing in there somewhere to help with the accuracy...
