Replacement Battery 2007 TE450

I am looking for an equivalent replacement battery for my 2007 TE450. Is the Yuasa YTZ7S or equivalent replacement correct? Is there a better and or cheaper replacement than the Yuasa?

Thanks,
Blake

I found some great info here: http://www.cafehusky.com/forums/showthread.php?t=1136

Just need to confirm that the battery I need is the WPZ-7s

Not cheaper but super light! 12 oz.

I have no affiliation, just intrigued by advancing technology.

Sounds awesome. Does anyone have any results with this?

I am concerned about running this type of battery since I have a Baja Designs 8in 55W Halogen and a trailtech SCMR16 HID light all running off my bike. I did have BD rewind my stator to give the max output. Does anyone think there would be issues with running an E-Batt?

I emailed Andre from eBatt:

And he replied back:

It looks as though he is willing to work with me, but I feel because I need the juice, and I don't necessarily need to drop the weight (although every bit helps) I'm going to go with the Power Source stock replacement.

So Power Source is out of stock until the first week in February with the WPZ-7s battery. I have called all the place that I think stock them, and can't find one. Any ideas?

as far as OEM replacements go Yuasa is a top line battery, Testimony from a few of my motoshop owner crew all sell Yuasa exclusively. Plus mine have never failed in my last 3 Huskies after mucho abuse, each on the 04 and 06 lasted for 2 years each and were sold with the bikes, my 08 is still going strong (not quite a year of abuse).

If you call, let me know what you find out!

Here's my interpretation:

Don't over look the small circuit that charges the Lith-ion battery. If the additional lights are connected directly to the battery, the current will come only from the battery, the stator cannot supplement as it's feeding the charging circuit, and the charger in turn is only feeding the battery the prescribed amount of current so as to not overcharge/explode the lith-ion battery. The charge rate for lithium-ion is 0.2 C to 0.7 C depending on manufacturer, meaning the charger circuit is only supplying 20%-70% of 2.3amp/hour.

If the lights are connected to the stator output only, including a ground that is not connected to the negative of the battery, then I agree there would be no problem. But anything drawing current from the battery directly would be limited to 2.3amp/hour + the charging current of 0.46 amp/hour to 1.6amp/hour. Not much total.
