Negative? Don’t know what you are talking about, just supplying additional information.
An ESC (any ESC, yours included) is under more strain in winter, not less, because conductive components have decreased resistance. It’s science. It also applies to your hardware.
The battery is indeed less efficient, but the strain on ESCs and other electronics is higher. I’ve had multi-rotor equipment fail and produce errors due to the above, despite decreased amps being pushed into the system.
As for Pusher. It seemed like he had difficulties relaying the issue/it was being misinterpreted. Just helping out.
p.s. In no need of your service. As mentioned before, will produce my own parts.
