Updated 3 days ago · Based on the Amazon listing and published specifications, not hands-on testing.
A light lithium drop-in for bikes that take the listed lead-acid sizes, with useful charge monitoring. Only buy it if your charging system uses a MOSFET regulator, since shunt-type or unregulated systems can damage it.

Overview
Swapping out a worn lead-acid starter battery on a sport motorcycle or scooter is the job here. TYKOOL builds this one on lithium iron phosphate cells with brass bolt terminals, an internal battery management system and a push-button charge readout.
Weight savings and a charge readout are the reasons to fit it, along with a sealed case for wet riding. The limit is the charging system: the listing demands a MOSFET regulator with stabilized output below a set ceiling, and vintage or modified bikes often need an upgrade first.
Who it's for
Riders of the Ducati, Yamaha and Kawasaki sport models named in the listing, and owners who store a bike through the off-season, get the most from it. Owners of older machines with shunt or missing regulators should wait until the charging system is upgraded.
Pros and cons
- Far lighter than the lead-acid battery it replaces
- Push-button state of charge readout
- BMS guards against overcharge and short circuits
- IP66 case sealed against dust and water
- Requires a MOSFET regulator; shunt types harm it
- Unregulated or over 15V systems need upgrading first
- Title and bullets give different CCA figures
- Amp-hour capacity not listed in specs or bullets
Performance notes
Starting power comes from the lithium cells delivering high cranking current to the starter, and the BMS cuts off when charge, discharge or current goes out of range. Charge acceptance depends on the bike's regulator: a stable MOSFET output lets the cells fill, while a high or unregulated output trips the BMS or damages cells. Low self-discharge means a parked bike loses little charge between rides.

Frequently asked questions
Will the TYKOOL LFP12B-BS-PRO work on an older bike with a shunt regulator?
Not as is. The listing says it is only for vehicles with a MOSFET regulator/rectifier with stabilized output under 15.0V. Shunt-style regulators, bikes with no regulator, and systems above 15V must be upgraded to a certified regulator first, or the BMS can trip and cells can be damaged.
Which motorcycles does the TYKOOL LFP12B-BS-PRO list?
Ducati Monster 696/796/1100, Multistrada 1200 (2010-2014), Diavel and 1098/1198 Superbikes, plus Yamaha YZF-R1 (2004-2014), YZF-R6 (2001-2005) and Kawasaki Ninja ZX-10R (2004-2010). Check your tray against the 150 x 69 x 130 mm case and left-positive polarity.
What charging voltage does this lithium motorcycle battery need?
The listing names 14.4V +/-0.2V as the optimal peak charging voltage and requires output under 15.0V. Verify your bike's charging voltage before installation.
Is the TYKOOL LFP12B-BS-PRO a lead-acid or AGM battery?
No. It is a LiFePO4 lithium battery built to replace lead-acid sizes such as YT12B-BS, YT12B-4 and GT12B-4.
How do I check the charge on the TYKOOL battery?
Press the button on the built-in digital SOC readout to see the state of charge, for example before or after seasonal storage.
