The strategy you describe sounds similar to the various charge/balance circuits that I have been exposed to for series charging. From the non EE perspective, I understand how these circuits work and have implemented some balanced chargers such as an 8s iteration-- but developing my...

Yes, however I am approaching this slightly differently from the usual charge strategies. To avoid the issues mentioned I am going to charge each cell individually and do away with the need to account for asymmetric cell performance. Each cell will have its own charge voltage...
@moltenmetal
Ha! You know what, the voltage at the cell was only 2.5V. I turned the supply up to 4V and got 2.6V at the cell @45A. It didn't occur to me that the supply voltage (bench) was not indicative.
Thanks, I can stop scratching my head about this [thumbsup2] !!!
Does anyone have experience with charging voltages for high C/charge batteries? I'm looking at LTO chemistry specifically, which is generally rated to take a 10C charge. Fully charged voltage is 2.8v/cell. All the literature I can find regarding the fast charging of cells, i.e. high C does...
