Hey everyone, nothing too pressing but for those who want the most recent firmware on the Satiator devices we now have a V1.023 release that you can upgrade to. Most of the changes are small behavioral fixes to allow the Satiator to better cope with scenarios of BMS circuits tripping and releasing and some risks of damaging the soft start circuitry if you disconnect and reconnect a satiator from the battery at just the right (wrong) moment. You should be able to just click "Get latest firmware" from your existing satiator software suite or you can download it again from here:

In any case, the main reason I'm writing is to mention that we have indeed experienced a much higher than expected issue rate on a recent (late 2016) production run of Satiator devices that we've been able to trace back to what seems to be a compromised batch of film capacitors. This was a real puzzle since we are inside the safe operating zone for the cap over the full operating voltage, currents, and temperature limits of the device, and had no capacitor issues in the first two years of widespread release. There are 3 tank caps on the device and if one of them fails then there will be frequent screen glitches and occasional "Pwr Fault" error messages, but when 2 or 3 of them go then the charger doesn't really work at all. When we disassemble the failed capacitors they all show signs of corrosion/oxidation of the metal film, while those from the earlier runs with 1000's of hours of use are all perfectly shiny all the way through.
It looks like a case where there was a manufacturing issue on the cap itself and we are pursuing an investigation to try and trace this.
Anyways, if somebody has issues with their Satiator along these lines regardless of where you purchased the unit from, please contact Grin directly by email and we'll sort things out under warranty right away. The capacitors are easy enough to replace but there are some risks in the disassembly and reassembly of the unit and so we'll generally want to have the device send back to us for repair/replacement, and we apologize for the inconvenience to anyone who is affected by this.
It's not at all what we wanted to have happen and sadly there wasn't an easy way to catch this earlier during the QC and burn-in steps.
