Gary, can't wait to see the townie in action - are you swapping the kit straight over from your folder? that would be an awesome setup!!!!
Are there any new micro logger developments?

I've been noticing a problem lately: different (intact) DeWalt packs discharging at significantly different rates - up to 2 fold. I use 2S3P PACKS, with 2 eloggers on 2 of them and a Whattmeter (WM) on a third (it would be nice to have 6 eloggers).
Here are data from two recent charges, using an elogger or WM on each (numbers are Ah to charge, same pack order):
1.33, 1.53, 0.79, 0.88, 1.29, 1.60
1.32, 1.14, 1.12, 0.72, 1.23, 1.36
A graph follows, showing packs 7 and 9 (third and fifth in the above line-up) being charged in succession by 2 series-connected 60 W photovoltaic panels.
Thinking that the DeWalt BMS' might be part of the problem, I'm going to remove the cell clusters and make up packs without BMS, but, following your procedure, I'll keep the cell taps assemblies. I plan to make just one cell tap harness, to use on each pack during cell voltage measurements and balancing.
Thanks again for sharing.
