The big downside to any small capacity battery is that you have to make sure you don't leave your lights on, or it'll kill the battery and thats no bueno. For that I installed a big red switch, but I might re-wire some stuff so all the big consumers get turned off if the engine is not actively spinning, just to be sure. If its just caps, its only annoying, they're not immediately worthless.

I might also get a small solar panel and a little (custom) charge controller to keep the battery topped up, so I can keep my clock and central locking and what else connected if the car sits for more than a week or two.

For $325 I could also install a pile of lipo's that 3x the stock battery capacity, but that wasn't the point, the point (for me anyway) was saving an additional 2% off of the total vehicle weight by deleting the lead.
