I'm researching to add to a real basic kit on a Sunseeker Fat-Tad recumbent. The most important feature I'm looking for is Amp hours consumed. I'd like to have a more accurate indicator of power consumed. Lots of generic units out there, so far it just looks like a slight variation in accuracy; https://www.amazon.com/s/ref=nb_sb_...ywords=rc+watt+meter&rh=i:aps,k:rc+watt+meter
