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).

Fantastic!!
Color: Dark Brown, Size: 10
This is the sharp, classy look you want for your child in a child’s suit! It is a nice true fit with a classy look. My son loves this and he was happy with the fit. He is a picky little guy and I was very happy with his response to the fit. The pants had a little glitch but that's ok! I’m so impressed.

Perfect Fit and Great Quality!
Color: Light Royal Blue, Size: 16, Color: Light Royal Blue, Size: 16
I bought this suit set for my grandson, and it exceeded all expectations. The fit was absolutely perfect—true to size and very flattering. The material feels high-quality and well-made, with attention to detail in the stitching and finish. He looked so sharp and felt comfortable wearing it, which made the occasion even more special. Highly recommend this set for any formal event!

Great value
This suit was the cutest for my son’s graduation. He is slim enough to fit a 5 but tall enough for a 6. I did get size 5, it fit good, except the vest was a bit on the smaller side. Luckily my boy is skinny. The quality is great. Definitely get your moneys worth. The only con I have is that this item was definitely worn before & likely returned to Amazon. The shirt was wrinkled and not packaged like a “new item”. It was in a regular plastic. You can see in the photo the wrinkles on the shirt sleeves.

Nice suit
This 5 piece set is really nice Pros: fits true to sz which allows it to sit nicely The pants have adjustable waist bands The color is as described Material/fabric is not that great but will do (select a neutral color which can prevent it from looking cheap) Perfect for a growing boy who will need another one soon Cons: The tie is little short and is a non adjustable elastic the handkerchief/pocket square does not fit in the faux pocket. If you want an elevated look - wear with a different tie, thicker fabric white shirt and nice shoes
