The TYKOOL LFP12B-BS-PRO is a compact LiFePO4 motorcycle battery that replaces YT12B-BS/ YT12B-4 models with 360 CCA, a digital SOC readout, and a lightweight 6Ah pack for high-compression sport and touring bikes.
If you ride a Ducati, Yamaha, Kawasaki or other sportbike that originally used a YT12B-BS-size battery, this TYKOOL pack delivers high cranking power in a much lighter, longer-lasting form. Built with iron-phosphate cells and a Pro-Series BMS, it’s engineered for sensitive electronics, tight battery trays, and wet-weather use while offering an easy drop-in physical fit for many aftermarket and OEM applications.
Yes—this model is dimensioned to match common YT12B-BS and YT12B-4 replacements with a slim 69mm width and left-positive [+ -] terminal layout. Confirm your bike’s tray size and terminal orientation before installing to ensure a correct fit and safe connection.
This LiFePO4 unit is over 60% lighter than a typical 7.8 lb lead-acid battery while providing strong cranking power—320–360 CCA depending on application—and thousands of deep-discharge cycles. Expect substantially lower weight, longer service life, and far reduced self-discharge during storage.
Because LiFePO4 chemistry requires controlled charging, the TYKOOL battery must be used with a MOSFET-style regulator/rectifier or a charging system that keeps peak voltage below 15.0V. Systems lacking a compatible regulator or outputting higher peaks should be upgraded to avoid BMS triggers or cell damage.
The battery’s IP66-rated case and low self-discharge make it rugged for wet rides and long storage periods, while the digital SOC readout provides a quick state-of-charge check with one button press. The slim profile and vibration-resistant interior are practical advantages for track days and tight chassis clearances.
Who is this for: The TYKOOL LFP12B-BS-PRO is aimed at sport and performance motorcycle owners who want a lightweight, durable replacement for YT12B-BS-size lead-acid batteries—especially riders of Ducati Monster/Multistrada/Diavel families and Japanese superbikes with narrow battery compartments. It’s also suitable for track riders, seasonal storers, and anyone upgrading to a modern MOSFET regulator to protect lithium chemistry. Verify your regulator type and terminal orientation before purchase to ensure safe, reliable operation.
Q: Is this battery a direct drop-in for YT12B-BS?
A: Yes, it matches YT12B-BS dimensions and left-positive polarity, but confirm tray size and terminal orientation before installing.
Q: Do I need a special regulator to charge this battery?
A: Use a MOSFET regulator/rectifier with peak voltage under 15.0V; shunt-style or >15V outputs are not recommended.
