I've forgotten so much from my original EV research and other related activities, that I had not considered the simplicity of a stand-alone meter in the circuit. The link provided presented a programmable meter for a pretty reasonable price. Correct me if I'm wrong in this supposition: programmable so it will interrupt the circuit when certain parameters are met? I downloaded and attempted to read the manual for the meter and was overwhelmed with the complexity of the device. I have a much simpler device in my velomobile that monitors my 12v battery "consumption" for the lights and accessories. It begins to register all the important parameters when connected and forgets them when disconnected. I've found a number of devices of similar construction with higher capacities than I need, so I won't burn it out, but it's not programmable. It also has a built-in shunt, so the external device would not be needed. (thanks M.R.)
Part of my original unclear message was aimed at how would I be able to charge these cells, but I can see now that a meter external to the r/c charger will provide the data while the r/c charger will give me the current and monitoring that I need. It's not like the charger bases the duration on amp-hours "pumped" back into the battery, so sequencing it two or three times won't cause an overcharge if left unattended at just the wrong moment, while the external meter can give me the total at the end. I'm not one to shy away from high tech stuff like the programmable meter, but it seems unwarranted in this case, as I already have sufficient complexity in the r/c charger. Whatcha think?

I'm going to use one to control my Volt module's charging, monitoring, etc.? They have a wide selection online at very reasonable costs.
