Anybody have personal experience with this compressor?

Just not more experience available.
I was out for some days and the attached 12 Volt LiFePo4 battery was working "strange", showing me very different voltages on the 4 cells … I have to re-balance and check-it first, dam… :/

It works, however I assume it will need longer test time to give some reliable informations

I used it now 7-8 times, but only for filling the guns bottles/tanks. I will not fill big scuba bottles with this small compressor. So the temperature reaches max 45-50 degrees. Seems 90 degrees are allowed for max.

Actually yes, but I assume it will really need some more time for testing. What when the compressor goes high after running 21 times ?

Still as mentioned a 12 Volt LiFePo4 battery with 20Ah capacity.
