It's a bit of a pain to remember how to set up and run this test so I've taken notes here.
To configure the three stages of discharge, switch mode to Battery and then press shift-(left arrow) for the
Batt Set menu.
For my 8AH Miady LiFePO4, I set it at 12.820v 2.00a / 12.810v 1.00a / 12.800v 0.50a to fully test battery
capacity. This battery instructs to "store at 75% charge and recharge every 6 months".
