Safe to use remote start, while the car is plugged into the Noco 5 maintainer?

As usual, Google you get "no problem" or "hell no"

Reason, remote start so the car can warm up, then disconnect and go.

I thought I remember you should not start the car on a maintainer.

Safe is relative, recommend is negative.

Let's see here. Battery dead, so we hook up a battery charger with Start Boost built in. Then we twist the key to spring things life, and we're worried about a max 2 amp trickle charger? Me thinks not!

At which point do you disconnect/disengage the start/boost or would you continue to charge. Is the bms smart enough to acknowledge the ‘additional’ compensation regarding the alernator?

Most (not all!) small battery chargers are based on measuring the voltage. Once you start the vehicle, the battery voltage will hover around 14 to 14.7 depending on the SoC. So any connected charger should just shut down. In any case, I'd be more worried about the charger, than any electronics on the vehicle.

Hence, safe being relative and recommended negative.
