Braille Lightweight battery

Has anyone here tried the subject battery and if so how did it do?

I have two of them in my small block stock eliminator car - one in front and another in the trunk. They worked just fine and I've had them for the last two years. I always top them off with an automatic, decreasing rate charger after each run.

They make several different sizes - mine were the 17 pounders.

I was looking at the 147-B3121 its 21 lbs and they are very compact. The cca at 32 is 742, which if they are what they advertise it should crank over my 604 with no problem. I think the idea of it being light and compact.
