The End of the Break-In?

Break-in testing continues. We're up thru cycle 22 with the basic CBAII and it appears that cell capacity has stabilized. Capacity varies a bit with discharge rate. 5A discharge produces 10.36Ah. 20A provides a bit between 10.08 to 10.13 Ah. A 25A continues discharge provides 10.19 Ah.

Comparing 10A loads, we've gone from 9.63Ah at cycle 1 to 10.26 at cycle 16 for a 6.5% gain in capacity. The experienced cell provides more consistent power until end of charge as well.

This is the end of our break-in tests for now. We've also reached the end of our discharge tests with our current CBAII configuration - 25A is the upper limit for a single cell. 26A does interesting things to fuses ...






Discharge cycle 23 at 10A is the first cycle with West Mountain Radio's 500W add-on amplifier for the CBAII. We'll increase the load 5A each cycle and see how these cells perform at higher rates. The cells are rated at up to 10C (100A) peak discharge.

Testing to date has been limited by equipment. Let's see how these cells perform when we open the throttle!
