The XS Power SuperBANK is perfect for high-power car audio systems, engine starting systems, and more. Connect in parallel with any lithium or AGM battery to make a customized power pack, delivering the perfect amount of energy on demand so your amps, battery, or engine gets every bit of power they need—whenever they need it. 

The SB500 delivers a surge of power to the factory 12-volt battery as it cranks, then rapidly recharges (usually in only a few seconds), ready to use again. The improved and  stabilized voltage leads to longer-lasting factory batteries, starters, relays, and engine control modules, improving reliability and lowering the likelihood of costly repairs.

Ultracaps (aka Supercapacitors) also work extraordinarily well in extreme hot or cold. In winter, the Ultracap delivers a much-needed burst of energy to vehicles using a typically slow-cranking AGM battery. Rated to more than a million cycles, the Ultracap is designed to work well in commercial vehicles or “daily drivers”, normally lasting more than a decade.

See specifications below.

Genuine leather upper and well made
Size: 10, Color: Sunlight
These shoes are well made and I love the way they look. They look great with jeans or dresses. I usually wear a 9 1/2 or 10 depending on the brand. These are a size 10 and fit. Hopefully after a breaking in period the opening at the toes will loosen up. Also, when walking they make a slap slap sound. Again, hoping after they break in that won't be the case. I got a great deal and poof a couple of days later there was a slightly better deal. I wasn't sure I'd like the color but it's actually really nice. The upper is genuine leather and they are well made.

Beautiful shoe
Size: 7, Color: Smoke Grey
This shoe is fairly narrow, which works fine for my narrow feet. Comfortable. Light. Nice color will match with lots of colors. Fairly comfortable but the skinny part by the toe I see how this would give anyone with a medium side foot blisters. It’s fine on me.

Runs small
Size: 8.5, Color: Sandstorm
This shoe is super cute and comfy. I usually wear an 8 or an 8½. I ordered the 8½, but it was too small, so I had to send it back. I reordered a 9, and it fit perfectly.

Love love these
Size: 7, Color: Black
Totally love these. I found them to run a bit short. I ordered a 6 1/2 (my normal size) - had to return them for a 7. But I love them.
