BLP5S - Group 5-12V Lithium Battery - Powersport Li-ion Phosphate - 120A for Motorcycles, ATV/UTV, Snow Mobiles, Personal Watercrafts, Scooters and Jet Skis - 4.45″ x 2.72″ x 3.35″

Seems to be good replacement battery. Used to replace a "heavy" AGM battery in my CanAm Spyder. Fits great after using the adapting spacers. Appears to be a good value. Seems to crank the engine right over, starting easily.

I don't impress really easy, but I am impressed with this lithium battery. I used it to replace the stock lead/acid battery in my Teryx 800 SxS. Living in Southern Arizona presents challenges with batteries and L/A batteries don't seem to take to the heat well (especially non-serviceable sealed L/A batteries). PROS - Weight (Fraction of what a L/A weighs), Fitment (Even though it is by nature smaller, it is in a case with spacers to adjust to your stock battery holder), Durability (TBD, but so far has already outperformed the L/A). CONS - Just a bit more expensive but anticipate a much longer life.

I bought the Bosch BLP14 battery for my Ibex 450 motorcycle, primarily for the weight savings. It arrived in good shape with the indicated multitude of spacers, and the terminal bolts and nuts. As usual I had to put little pads under the nuts to locate them in place and raise them up to where the bolts would easily engage them - why we still have to do this after decades of this poor design I don't know. Otherwise, it went in easily and the bike started and runs fine. Time will tell how it holds up, but I suspect this battery from a company like Bosch should do well. Now, regarding the battery dimensions. The Amazon description for this BLP14 variously shows it as "3.43"D x 5.91"W x 5.63"H" and "3.43"D x 5.91"W x 3.63"H". The Bosch website was no help on this mystery, but I suspected it was the smaller height for this Class 14 battery. I measured it and in fact the actual height is 3.63" so it should fit as a replacement for batteries such as a Yuasa YTZ14-BS. The 5.63" measurement would reflect the use of some of the included spacers to raise the battery height, if needed. Hope that helps!

Installed in a friends BMW 800 and works well ,will sit out at night, always cranks , even better as it it like 13.2 volts so cranks fast

You have to make this battery fit in your motorcycle. It is much smaller and lighter than your original battery, and it comes with lego-like blocks to help it fit in your battery box. Wouldn't work in my bike, even though the battery was cataloged as the correct model. These lithium batteries are light and they are small, but they are not plug 'n' play. I returned mine to Whole Foods and bought a normal maintenance-free battery.

Cranks the motor better than stock. Much lighter than stock battery and notice it during daily driving. Ingenious mounting blocks that make the battery fit perfectly. So far, so good.

seems to work great, plenty of power to start my snowmobile!

Battery works great in my gsxr750
