4s 2200 lithium used to jump a 'full scale' chevy minivan

In a pinch,I managed to jump start a chevy minivan who's battery was not fully dead but depleted below cranking ampheres, just wouldn't turn over. I had just been flying,took my 4s 14.v 2.2 amp battery from my Conscendo connected positive to positive, negative to negative & turned the key,car started right up! I'm told if that can be avoided,it's dangerous to the car,car battery, plane battery & myself. Lithium might have blown up, combining voltages could have transmitted a homing beacon to attract intergalactic homicidal telemarketers, and the subsonic noise produced irritates whales, who having heard the noise,will never mate or reproduce again.
Seriously, while I unplugged the battery the moment the engine started,I understand I should not drive like that,why is what I did more dangerous that using a battery on a glow engine for example?

Most of these compact "Jump starter" lights emergency radio thingies are lipo powered. MANY videos on the utubes where people have drained a car battery charging packs all day at the field who jump started their car from a lipo pack.

You know that's what l said, dude who owns the van,was getting ready to call a tow truck when I jumped in with my airplane battery, he hadn't seen what I did,when I told him he said it was a good way to start a fire,I mentioned the portablejump start thingies are lithium powered,he said they had circuitry designed for that purpose. Whatever,I did not really think it was so terrible what I did,and he didn't have to pay a tow truck,now he's pissed his clock is reset,thinks I 'fried' something. Lesson learned, don't try to help save $50-100 for a tow truck to a reactionary yet uninformed automobile owner!
