so far Icharger is doing a great job at the difficult job of top balancing lfp cells . Cell #5 is max charge of 3.5v . The charger is holding it there but still putting in 18.26a into the rest of the cells . The cells were in low voltage storage mode about 80mv apart . charger now has them to 58mv . The pack has already taken 62.7ah and based on the amps it is still taking they should go over 70ah , impressive .
