For a track car where support is nearby I can see the appeal. For a road car...I would never recommend a small battery.
I want peace of mind that my battery will work, and work for a very long time if things go wrong.
Ive been tempted many times by a race battery, but just cant bring myself to do it.
Well that will be a potential downside that if your cranking for a long time then you do risk running out of juice.
Luckily its never happened to me when ive been somewhere, if ive built an engine and going for the first start to get oil pressure and also get it running I would be doing this at home anyway so ill hook up to a big battery to cover myself, after that your good to go on the little one.
I suppose for yourself(assuming your in the granada) running one would only reduce the your overall weight by 0.6% where for me its closer to 1.5% again small numbers but im aiming for 680kg from starting with 780kg so every little helps.
When you mention fans, I assume we are talking them running when the engine is off?
Ive had fans running for about 30seconds then start the vehicle, seemed ok, but then I cant guarantee that for everyone and different fans due different amount of amps
