The price/performance ratio is still very good, the battery is well-made and seems to be exactly as specified. This battery is much better to use and is much lighter. Excellent value for money!
The Pro Performance motorcycle battery with 180 cranking amps is fantastic! It provides excellent starting power, even in cold weather, and the 180 CCA gives me confidence that my bike will start every time. It’s been performing flawlessly, with quick cranking and no issues after several rides. The battery is compact yet powerful, and it fits perfectly in my bike's compartment. I’m really impressed with the overall quality and longevity so far
I can’t believe how light is this battery my monster weights more than this GREAT BUY
I have a 2007 Suzuki M109R boulevard this has an 1800 cc V-Twin engine in it... It takes a good battery to turn this engine over... I tried two other batteries.... The first was an AGM battery that advertised 230 cold cranking amps.... It had trouble turning this engine over... When the engine was warm it would sometimes take three presses of the starter button to get it to rock over and start cranking... The second battery was a lithium battery manufactured by Weize and it advertised 500 CCA..... Unfortunately the rating of this battery was false and it had similar issues as the AGM battery... After reading several reviews I decided to go with the tycool lithium.... It has a rating of 480 cold cranking apps and let me tell you this battery spins that engine over like a capacitor discharge..... So it took me a bit but I finally figured out what battery to buy.... If you have a Harley or some other V-Twin powered motorcycle this is the battery you're going to want.... I kept hitting the starter and then shutting it off I did that about eight times and every time it's like a bolt of lightning....
Battery arrived on time and fully charged. It's surprisingly light weight and starts my Honda Valkyrie with ease. Very happy with this purchase. I have recommended this battery to friends.
This little battery is crazy small but still puts out the power! I'm using it with a small tractor and it has no issue cranking over a 25 HP engine, even when cold. I'm impressed. It does not cost much more than a basic replacement lead acid battery but will last much longer. The LiFePO4 batteries that I have put in my household UPS devices have been in place for 4 years now and have not lost any capacity. I know this is a different application all together but I use that mower every few days all summer long and the battery still cranks just as good with the temperature near 20°F as it does when it is 90°F outside.
Lithium batteries are the only way to go
Comes fully charged 13 volts. Very easy installation. No issues so far. Hard to find a lithium battery at this price.
Works great in my 2011 BMW K1300S! What's especially nice about this Battery is the weight advantage it has over the OEM AGM Battery. The Battery is located directly behind the Steering Head on the K1300S so this puts lots of Mass in a place you'd rather it not be. My K1300S feels a bit easier to flick side-to-side so this is very helpful for quick maneuvers. Install was a direct form/fit/function replacement. Like the Digital Readout on the top too!
I like how this has a display to show the charge. Wish all batteries had this feature.
