You posted a diagram of individual cell monitoring device. Did you make these or purchase them?

I too am a simple man and those EV guys will argue top balance vs bottom balance all day long. It's like which is better, Ford or Chevy.
I didn't use Lightobjects Ah meter.
I also didn't post an individual cell monitoring device, I posted a cell balance warning device. It's not available as a "kit", you have to make it yourself. It consists of a few LED's and a couple resisters.
The purpose is to instantly let you know if a cell goes high of low. It is highly accurate depending on the resister value used. It does not tell you which cell went high of low though. That didn't worry me, I liked the fact it was always monitoring the pack and was under $10.
