Upgrade to 656 !

Around November 2016 SPORTident posted the latest version of the SI-Config+, along with a new firmware version (656). As there are known deficiencies in firmware versions 623 and 649, it is strongly recommended to upgrade any controls with 600-series firmware to 656.

Some more details on battery conditions

In a previous post I mentioned that if the voltage drops below 3.3V, it indicates that battery end-of-life is getting close.  I briefly want to elaborate on this. Below is a diagram of the battery discharge based on current draw. It is published by the battery manufacturer, for the battery installed in BSF-8 controls (BSF-7 batteries have similar looking profiles).  As  can be seen, the voltage level is extremely stable and only drops off near the end of the battery’s life.  The green curve best describes the SI control’s profile when the control is active with punches from time to time...

BSF6 and single-cell lithium batteries

SPORTident now uses single-cell lithium batteries to replace BSF6 batteries instead of Alcaline triple cell packs as originally shipped.  The lithium batteries last much longer than the original packs, and the voltage stays within range until almost the end of the battery’s life. There are two aspects that need to be considered.  1) As stated elsewhere, there are three indications of battery well-being for lithium batteries.  One is the actual battery voltage which is somewhere between 3.3V and 3.7V.  A lithium battery maintains this voltage for most of the battery’s life, but then drops quickly off –...
