Power Shelf Upgrades and Outdoor vs. Indoor Testing

Upgrading the Power Shelf wiring and some outdoor vs. indoor capacity testing results.

I added some solid core 14AWG copper jumper wires from end to end of the nickel strips that connect the cell holders in the power shelf. I also bumped the charging leads from 14AWG to 10AWG to help reduce voltage drops while testing.

This and testing inside at a more consistent temperature resulted in decent capacity gains and much more repeatable test results.

Since I need to build packs to a common capacity to allow for future reconfiguration, I need to have consistent test results. This way I can measure capacity, then swap some cells and retest to see the result.

Once I get the test procedure down, I'll run all 10 packs I have cells for, so far, and then select a target capacity. Then I'll work at bringing teach 20P pack nearer to that capacity.

The 4S pack powering the charger is described in this video:

To be continued, next up, looking at testing of the 4S pack and cell voltage drift during cycling:
