It’s probably nothing serious but still confusing enough, so I thought I’d bring it up here.
On two copters both running Kakute F7 AIO I have to adjust BATT_VOLT_MULT to two different values in order to get the correct voltage shown. On one it’s 11, on the other 12.1. Moreover, the wiki says it should be 10.1 (Holybro Kakute F7 and KAKUTE F7 AIO — Copter documentation).
I’m just wondering how this can be - a change in hardware by Holybro maybe? I bought both FCs 2-3 years ago, but one of them is a year older if I remember correctly.
