Skyrich 12V LiFePO4 Motorcycle Starter Battery HJTZ5S-FPC — 2Ah, 120CCA, IP67 Waterproof & Vibration-Resistant

Skyrich HJTZ5S-FPC is a lightweight 12V LiFePO4 motorcycle starter battery (2Ah, 120CCA) designed as a direct OEM replacement for YTZ5S-style applications and built for off-road and powersports use.

If you need a compact, vibration-resistant battery that fits KTM, Triumph and similar dirt-bike starter housings, this Skyrich model provides the performance and certifications expected of an OEM-supplied unit. It pairs high cold-cranking capability with an integrated BMS, IP67 waterproofing and advanced thermal and vibration engineering, making it suitable for harsh trail conditions and regular road use alike.

How does this battery perform when starting in cold or rough conditions?

The HJTZ5S-FPC uses fifth-generation LiFePO4 cells that deliver strong cold-cranking amps while keeping weight low. Internal potting and military-grade vibration resistance reduce failure risk on rough terrain, and the battery maintains usable voltage under load for reliable starts.

• 120 CCA rated for effective starting power in low temperatures
• Gen 5 LiFePO4 chemistry for high power-to-weight ratio
• Internal potting resists vibration at 15G for 20 hours per axis
• Thermal management to avoid overheating during heavy use

Will it fit my bike and replace a YTZ5S battery?

This Skyrich unit is built as a genuine OEM-form replacement for YTZ5S-sized batteries and specifically fits many KTM EXC, SX-F, FE and FC models, plus certain Triumph MX models. Confirm terminal orientation and dimensions against your bike’s battery tray before purchasing.

• Direct-fit dimensions for YTZ5S-style housings
• Compatible with KTM EXC 250/300, SX-F 250/350/450, FE/FC 250/350/450/501
• Suitable for Triumph MX250 and similar powersports machines
• OEM supply lineage — Skyrich parts used by KTM since 2014

What protections and certifications does the battery include?

The battery includes an integrated balancing BMS and is sealed to IP67 waterproofing standards. Its safety profile is validated by multiple industry tests and certifications, ensuring compliance for shipping and field use.

• Integrated balancing Battery Management System (BMS)
• IP67 rated for dust ingress and temporary water immersion
• Passed abuse tests, EMC, UN38.3, CE and RoHS certifications
• Designed with thermal control and safety-conscious cell architecture

How do I maintain and charge this LiFePO4 battery properly?

LiFePO4 chemistry requires a charger compatible with its voltage profile and charge algorithm for longest life. Use a charger designed for LiFePO4 batteries, avoid over-discharge, and store at partial state-of-charge if the bike is unused for extended periods.

• Use a LiFePO4-compatible charger or smart charger with LiFePO4 setting
• Avoid deep discharge; recharge after each significant use
• Store in a cool, dry place at about 30–50% charge for prolonged storage
• Periodic balancing is handled by the built-in BMS

Who is this for: The Skyrich HJTZ5S-FPC is aimed at riders and mechanics who need a compact, OEM-quality LiFePO4 starter battery for off-road, motocross, enduro and lightweight street motorcycles. It’s best for users who value weight savings, durability under vibration and water resistance, and those fitting YTZ5S-form batteries in KTM, Triumph and compatible powersports machines. If you want an OEM-grade replacement with robust safety certifications and minimal maintenance demands, this battery is a practical choice.
