Our Braille B3121 lightweight AGM battery is our lightest do everything battery yet, weighing in at just under 22 lbs. Using our Advanced AGM racing technology, we have put a lot of power into a very small package.

With 1380 pulse cranking amps this has enough power to start more than any other battery in its weight class. This is the perfect model for those who want to shave half the weight of a standard Group 34 battery and still have enough power to crank over a street car with V8 engine & standard compression.

Used in everything from large Harley Davidsons to Hot Rods, road race cars, Corvettes & Vipers. (Note: while high in cranking amps, make sure battery has enough capacity for the vehicle intended to be used in.  Not designed for big block, high compression motors, those with no alternator, etc. (Where a full-size battery with high capacity is required).

YIX30L, YB30L-B, ETX30L, HD 66010-97

Cute but slim fit not wide foot friendly
Size: 8.5, Color: Black
Bought these and they were so cute! The only thing was they were wide enough and I don’t typically have a wide foot. I would maybe size up or look for a wider fitting shoe if you have a wide foot. But the style and heel height were perfect not to high! I ended up returning because of the slim fit.

Love these
Size: 8.5, Color: Coffee
So comfortable, stylish, and easy to wear. This can be used with any outfit, whether it’s casual or something more dressy like for work. They are comfortable and easy to wear for eight hours at a time. Heel is nice and thick and very stable, which makes for walking in a heel very comfortable. The color is a beautiful nude, which does not look too chalky or too brown. This is a stable in my

Great nude shoe!
Size: 10, Color: Nude
Perfect nude dressy heal. Was not uncomfortable at all. I thought my toes would be sliding out. I did put grips on the bottoms because they are a tiny bit slippery and I am prone to falling. Cute and didn’t distract from my dress.

Only wear for short distances
Size: 8, Color: Nude
These heeled sandals were very cute and flattering. After a couple minutes of walking, my feet began to hurt. I got blisters upon removal. A few days later I tried wearing them again, it is still extremely painful. Great for pictures though!
