Anyone heard of this brand?

I was looking for lithium battery charger and found this site.

I've seen plenty of lightweight motorsports batteries in the last few years that no one has ever heard of. I don't know how good any are compared to the companies that were in on the ground level. A friend bought an inexpensive lithium battery for at least one of his bikes and I never heard him complain about in the last 5 years. Full Spectrum is a good one. I'm sure Shorai is still most popular and I think those are awesome, just don't ever let one run down below 9v or whatever they warn against. It seems to impair the battery's ability to hold a charge very noticeably and even after just one time drawing down that low.

In addition to Rooks comment. be sure you read teh info that comes with whatever you choose. You cannot treat the new batteries like the old ones. I came close to exploding a Shorai by jumpstarting my bike with my truck. I have been using a ANTIGRAVITY BATTERY AG-801-8-cell for about 2 yrs now with no problems . It was $179.00
