So I did Thor flashing yesterday and according to idrove drained the battery. Luckily the flash completed and it started up fine.

I don't own a battery charger but have an 18,000mah Arteck (Seems well made) jump starter battery. So in theory it can provide nearly 18Amps for an hour.

Now I know it's not to CHARGE my battery. But is there anything precluding me from leaving it connected while flashing the car to reduce stress on the lead acid battery in the car?

Arteck instructions say when car has started to disconnect the unit within 15-20s, so presumably the answer is no and I need to invest in a charger.
