TYKOOL LFP20L-BS-PRO Lithium Motorcycle Battery — 600CCA, 12Ah, Digital Readout (Replaces GYZ20L)

Overview

The TYKOOL LFP20L-BS-PRO is a high‑density lithium motorcycle battery designed to power modern bikes and watercraft with reliable starting power and advanced electronics support. Built to replace popular GYZ20L variants (GYZ20L, GYZ20HL, YTX20HL-BS) and compatible with OEM units such as 65989-97A/B/C, this model blends a lighter footprint with stronger ignition potential. Its integrated digital readout keeps you informed on the go, while a rugged build emphasizes durability in demanding conditions. This isn't a guarantee of results, but it is designed to offer crisper starts and steadier power for a range of engines and accessories.

Key performance and energy storage

• 600CCA starting power and 12Ah capacity provide quick ignition and steady support for higher‑draw electronics.
• Expanded 12Ah energy reserves help run modern Harley electronics, high‑output lighting, and premium audio with fewer voltage dips.
• Deep discharge resilience and controlled energy delivery support longer standby times under heavy electrical loads.
• CAN‑bus compatibility considerations help keep essential systems active during storage without vampire drain.

Precision fit and rugged design

• Exact dimensions: 6.89 x 3.43 x 6.10 in (175 x 87 x 155 mm) with the standard [- +] polarity for Harley and Polaris trays.
• Reinforced, vibration‑isolated terminals designed to handle the current demands of touring and performance applications.
• IP66 waterproof rating and industrial‑strength housing deliver durable, weather‑ready performance in diverse environments.
• Flame‑retardant housing and robust sealing resist moisture, dust, and heat exposure during rides and storage.

Smart telemetry and longevity

The integrated Digital Readout LCD provides real‑time battery health data. The PRO‑series BMS balances cells with precision, protecting against over‑voltage and thermal stress, and aiming for extended deep‑discharge cycling over time.

Usage scenarios

Designed for heavy‑displacement cruisers and touring bikes such as Harley Ultra Limited, Road King Special, and Fat Bob. The energy‑dense cell supports CAN‑bus devices and keeps accessories powered when stored, reducing common drain issues associated with standard lithium units.

Charging and care

• Use only dedicated LiFePO4 chargers and comply with regulator output guidance (under 15.0V).
• Avoid lead‑acid pulse‑repair or desulfurization modes to protect the internal BMS and overall longevity.
