Hello again,
During the past few months of bring up and testing I was reviewing my notes and noticed the SOH parameter hasn't changed since my initial learning cycle.
I've been using the batteries down to about 20% SOC daily, sometimes down to 0%, then recharging. I'm doing this about twice daily, though not at regular intervals or with consistent rest periods.
The initial value after the learning cycle for three setups was 2995, 2981, and 2961 for a Design Capacity of 3000mAh. (Cell is 2900mAh min, 3000mAh typical). The SOH at that time was 93, 92, and 93% respectively.
The numbers are now 93, 92, 91% with FCC of 2517, 2559, and 2403. I should note that one board is using CCCV, one is using MLC, and one is using MLC w/SOH Compensation.
Just hoping to understand this better before I commit to a GG file...
