TYKOOL LFP12B-BS-PRO Lithium Motorcycle Battery 6Ah 360CCA Left-Positive, Pro BMS & Digital SOC

TYKOOL LFP12B-BS-PRO is a compact LiFePO4 motorcycle battery delivering 360 CCA and 6Ah capacity as a lightweight, maintenance-free replacement for YT12B-BS/ YT12B-4 batteries.

This high-performance lithium pack is built for modern sport and superbikes that demand reliable cranking power from a small footprint. It combines a robust Pro-series BMS, a visible digital state-of-charge readout, and an IP66-rated housing so you get long cycle life, better cold starts, and safe protection against common electrical faults when your bike’s charging system is compatible.

Will this battery fit my motorcycle model and battery tray?

Measure the tray and confirm polarity before ordering — the LFP12B-BS-PRO is specifically engineered to replace YT12B-BS, YT12B-4, and GT12B-4 footprints and features left-positive [+ -] terminals. Its slim 150 × 69 × 130 mm dimensions and low 2.4 lb weight make it suitable for narrow chassis and tight airbox clearances on many sportbikes.

• Exact dimensions: 150mm × 69mm × 130mm (5.91" × 2.6" × 5.12").
• Polarity: left-positive configuration [+ -].
• Drop-in design for common YT12B family trays with brass terminals.
• Ideal for bikes with limited space (slim 69mm width).

How does the battery manage safety and longevity?

The integrated Pro-Series Battery Management System protects cells from overcharge, over-discharge, excessive current, and short circuits. Combined with LiFePO4 chemistry, it provides thousands of deep cycles and a long service life when paired with a compatible charging system.

• Built-in BMS for over-current and short-circuit protection.
• Digital SOC readout to check remaining charge with one press.
• Ultra-low self-discharge (<1% per month) for seasonal storage.
• Expected long cycle life from LiFePO4 cell chemistry.

What charging system does my bike need to use this battery safely?

Use only on motorcycles with a modern MOSFET-type regulator/rectifier or an approved regulator that stabilizes charging below 15.0V. Shunt-style regulators or chargers with peak voltages above 15V can trigger the BMS or damage the cells; verify peak charging voltage (around 14.4V ±0.2V optimal) before installation.

• Required: MOSFET regulator/rectifier or certified equivalent.
• Avoid: Shunt regulators or systems that exceed 15.0V peak output.
• Recommended check: measure peak charging voltage before fitment.
• Upgrade regulator on vintage/modified bikes if needed.

How does this battery improve starting and track performance?

Delivering 360 CCA in a fraction of the weight of lead-acid batteries, the TYKOOL LFP12B-BS-PRO offers stronger cranking and quicker throttle-to-life response while keeping mass low for handling benefits. Its slim profile and vibration-resistant internals are tailored for high-compression V-twin and inline-four starters found on many superbikes.

• 360 CCA for reliable cold and hot starts.
• Only about 2.4 lbs — cuts significant weight from OEM lead-acid packs.
• Vibration-damped internal structure for road and track use.
• Specifically tuned fit for Ducati V-twins and Japanese sportbikes.

Who is this for: Motorcycle owners and racers who need a compact, high-cranking lithium replacement for YT12B-family batteries—especially riders of Ducatis (Monster, Multistrada, Diavel, superbikes) and sportbikes like Yamaha R1/R6 and Kawasaki ZX-10R—provided the bike has a MOSFET-style regulator or an upgraded charging system. Choose the TYKOOL LFP12B-BS-PRO when you want dramatic weight savings, an on-board SOC display, durable IP66 protection, and the safety of an integrated BMS for daily riding, storage, or track days.
