Delivering up to 180A CCA, the TYKOOL YTX4L-BS-PRO provides fast, confident starts and clearly outperforms standard lithium options (140A) and traditional lead-acid batteries (80A). Built for long-term use, it also offers an impressive 3,000-cycle lifespan—surpassing standard lithium (2,500 cycles) and far exceeding lead-acid (~300 cycles)—making it a reliable, high-performance upgrade for serious riders.
The TYKOOL YTX4L-BS-PRO lithium battery is designed to cut weight and eliminate upkeep. At only 1.2 lbs, it’s dramatically lighter than a typical lead-acid battery (about 3 lbs), making handling and installation easier. It’s also completely maintenance-free—no activation, no acid, no leakage concerns, and no routine servicing required. Shipped fully charged and ready to install, it delivers clean, hassle-free power for motorcycles and other powersports vehicles.
The TYKOOL YTX4L-BS-PRO High-Performance LiFePO4 Motorcycle Battery integrates a smart Battery Management System (BMS) to help keep operation stable and safe. It delivers key protections such as over-charge, over-current, short-circuit, and over-discharge safeguards, plus cell equalization/balancing for consistent energy output and long-term reliability. For added control, the digital readout displays both State of Charge (SOC) and voltage at a glance, making it easy to track battery status and maintain peak performance.
Built for an easy drop-in upgrade, this lithium battery is made in a 1:1 OEM battery size, so it installs cleanly with no trimming or modifications. The solid brass terminals provide strong conductivity and added durability for a secure, stable connection. With compact dimensions of 4.45" × 2.79" × 3.38" (113 × 71 × 86 mm), it maintains a perfect fit while delivering dependable, high-performance power across a wide range of vehicles.
Built for modern riders, the TYKOOL LiFePO4 lithium battery delivers reliable starting power and long-lasting durability across a wide range of applications—including motorcycles, ATVs, UTVs, PWCs, and scooters. Designed as a direct upgrade, the YTX4L-BS-PRO Battery replaces common OEM sizes such as YTX4L-BS, YTZ5S-BS, YB4L-A, and YT4L-B, making fitment simple and worry-free. With advanced engineering and safety-focused testing, TYKOOL provides a lightweight, high-performance power solution that’s ready to keep you moving—on the road, trail, or water.

Bought this to replace the battery for my Lifan Expect 200 cc dual sport bike. Aside from the battery bracket not fitting over it, it’s been perfect. The battery bracket, in my opinion, is not really needed as the seat holds the battery securely in place. The bracket might fit if I bent it some or made some other modification, but I havnt bothered.
The battery works fine and the customer service for the battery I replaced was excellent.
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.
