5.2.1. Over Voltage
If the connected battery voltage is higher than the max voltage for the profile, then the display
will produce a voltage too high error. This error screen will persist until the battery is removed
5.2.2. Short Circuit
If the Satiator senses that the output pins are either shorted together or have a reverse polarity
voltage, then display will show a short circuit fault. This will clear once the short circuit or
reverse polarity is removed from the output plugs. If you see a short circuit fault even when no
battery is attached, then that could also be a sign that water or other conductive residue has
contaminated the charging connector and is bridging the pins.
5.2.3. Power Stage Fault
In certain situations, it is possible for the Satiator’s onboard over-current protection to trip. When
this happens, the Satiator will not be able to output any current, so if you plug in a battery it will
show the battery voltage correctly and attempt to charge but it will display 0 amps. This
condition is reset by powering the Satiator off and on again.
5.2.4. OLED Screen Glitch
If the AC input to the Satiator is quickly interrupted and restored while the Satiator is charging a
battery pack, then it is possible to corrupt and freeze the OLED display even though the Satiator
is still charging fine in the background. Pressing either button will reset the display, as will
waiting for it to enter screen saver mode.
5.3. Cell Balancing
With lithium packs, it can happen that the battery stops charging abruptly because the BMS
circuitry has tripped from a cell overvoltage fault. If the battery's management circuit does cell
balancing, then this high voltage cell will be bled down to a release voltage and then the
charging will resume again. This process can sometimes repeat many times, especially if the
pack was largely unbalanced. Even though the charger says "Charge Complete", it will still
resume the top up charges as the BMS circuitry allows so that the pack can fully balance out.
