WPS Western Power Sports Featherweight Lithium Battery

I've been using these batteries for a few years now. Though I had an issue with my bike which ended up draining the battery, the battery itself works fine. The battery is significantly lighter than a stock battery and is smaller as well.

Batteries worked great. Light and seemingly well built. Will have to see longevity. A little larger than OEM but only very slightly.

I bought mine in 2017 to go in a 02 ZX6R. Like others when I got the box I thought I had been scammed cause it was so light. I have never had a problem with mine and I let me sit over New England winters without a trickle charger. Maybe I just got lucky but after 2 years of reliable service I'm sold and know buying one for my RC51 since it's lead battery did not survive this winter.

UPDATE - This battery was almost completely useless. It worked for about a month, then the bike sat for 2 weeks. It had enough juice to start the bike, but left me stranded 2 hrs from home. When I got it home and put it on an approved charger, it wouldn't a charge.This battery fits great in my 2006 Kawasaki Ninja ZX-6R (636cc). Battery came fully charged, bike cranked first try. This battery weighs maybe 1 lb. The battery it replaced weighs approximately 9 lbs. When I picked up the box I thought they shipped me an empty package. I'll update this review is I discover any negatives to this product.

I had read other reviews and not 100% bought in to the thought of a Lithium battery, but for less money then a regular battery locally I figured I'd try it out. This thing is stupidly light, to the point that it's hard to believe there is anything even inside of the plastic case. This model does have the + lead on the left side unlike the main picture. Mine also can fully charged and all voltages showed as they should. 13.2v sitting there and 14.3 when the bike is on. We will see how long it lasts, but am optomistic.

Fit perfectly and was fully charged upon arrrival. Fast shipping. Time will tell on how long the battery actually lasts.

Using this in a 2018 Triumph Street Triple (765 R). Works a treat after almost two years of duty. Super light (and a great way to reduce "up high" weight on the bike).

These battery’s do not last long at all. From the start I never had much cranking power. By 4 months I was at 50%. Not happy with this purchase. Stick to a brand name that you know and trust.
