Full Spectrum Power Battery

I've become interested in the Pulse 2 battery from this company which only weighs about 2 lbs.  I was wondering if anyone knows whether these are "recharged" while riding or if they are just a racing product to be used and discarded after a few starts.  The website is a little unclear on how these batteries maintain their charge.  The website says something about disconnecting the battery when not in use, but nothing about how long they last compared to a regular lead-acid battery.  Any help would be greatly appreciated.  

Provided you follow their recommendations for your bike and intended use, it should work OK. As long as you don't have any extra accessories (HID headlight, extra lights, etc.), and you don't encounter any starting problems that require you to run the starter motor for extended periods, and you disconnect it after every ride, you should be OK.

Any situations that cause an extended power draw on the lithium ferrous cell battery will kill it off in short order, because it doesn't have the reserve capacity of a lead acid battery.

Your generator/rectifier on the bike should recharge the battery as long as you don't do continuous 5-minute trips down to the corner store.  

Thanks Kento.  I guess the battery might be worth getting for those days where pure sport riding or track days are on the menu.  I can always keep a fully charged regular battery to put in for those rides where I might be stopping and turning off the engine frequently.  I guess I'll just have to try the Pulse 2 to get a really good idea of how it performs because I can't ignore a weight loss like that.  

I could save more weight by just going on a diet.  

If I lost almost 10 lbs., I'd still want another 7 lbs to come off my bike.

Hi- sorry for the late response. I'll try to add to what Kent mentioned. (Thanks Kent!)

The Pulse P2 weighs about 1.6lbs, or 700g. We recently revised the Pulse line to be roughly 11mm shorter as well as more rigid in the terminal area.

All of our battery systems are meant to be plug and play with a standard motorcycle charging system. They will recharge while riding. While the racers and serious track riders will be the largest user group, street riders will also benefit from our battery with faster starts, increased life, and lighter weight.

Life span is an interesting topic. I am still using the very first battery I built in 2007. It has migrated from my RC51 superbike, to my 1098 superbike. The 1098 has been sitting in my shop since March 2010 without being started...
Our supported race teams have reported similar results. As an example, the Yosh bikes have accumulated more than 5000km this season on a single battery, and the systems show zero loss of capacity.
According to the CBA (computer battery analyzer) it has lost 0% capacity since I initially tested it. This is especially impressive (imo) as I have taken no special care to ensure its performance. I have treated it as I would imagine most riders would treat their battery. So, if you use this as a guide, you should expect one of my systems to outlast your bike. ymmv.

The cells that we use in our systems will lose roughly 5% charge per year while sitting unused. This is one reason why we recommend simply disconnecting the battery during the winter. We recently introduced the Pacemaker, which is the first and only maintenance charger for 12v lithium battery systems, for those of you who ride a few times a month, and want to have their battery in top condition, without disconnecting it.

Note that a bike that normally drains a stock battery while sitting- a bike with LOJACK, and alarm, immobilizer, etc- will need the Pacemaker to remain charge while not in use. This is no different than using a Tender type device on a lead acid battery.

If you have other questions about this technology, how it works, use cases, or anything else, please post them and I will try to respond. If you need questions answered immediately, send an email to info@fullspectrumpower.com

Thanks!

Awesome!  Thanks for the info, I am definitely planning on putting the P2 into my bike before next Spring.
