YTX14-BS Lithium Motorcycle Battery 12V 8AH - Lightweight High CCA

In this review of the YTX14-BS lithium motorcycle battery the bottom line is straightforward: this pack is for riders and powersports owners who need a very light, high-cranking battery that fits YTX14-sized spaces. The reviewer found the single biggest reason to buy is the combination of low weight and strong starting power - a 12.8V, 8Ah unit with a MAX CCA of 600A that starts engines reliably while weighing only 2.76 pounds. That makes it especially attractive for motorcycles, scooters, ATVs and PWC where weight and fit matter.

Key Features

• High cranking power: MAX CCA 600A provides strong starts for small engines and many mid-size applications.
• Lightweight design: At 2.76 pounds the battery is roughly one third the weight of a comparable lead-acid unit, reducing carried mass and improving handling.
• Compact dimensions: With physical size 5.9 x 3.4 x 5.7in it fits standard YTX14 battery compartments and common equivalents when polarity and space match.
• Wide operating range: Discharge and charge temperature windows allow use in a range of climates from cold starts to warm charging environments.
• Built-in safety: Integrated BMS protects against overcharge, over-discharge, short circuits and overheating to extend service life.
• Multi-position mount: The lithium chemistry and construction allow mounting in various orientations, useful for custom or tight installations.

Who It's For

The YTX14-BS is best for motorcycle and powersports owners who prioritize weight savings and reliable starting performance, including scooter riders, ATV drivers, jet ski and waverunner users, and anyone replacing a YTX14-series lead-acid battery. It is a practical upgrade for riders who want faster cranking and less bulk without changing the battery compartment.

Those who should look elsewhere include users who lack the correct charging setup or who need a battery for heavy continuous electrical loads; the recommended charger is a 14.6V DC lithium charger at 1-2A and users without access to compatible charging may prefer a conventional lead-acid option. Also, if an exact fit or terminal orientation does not match the vehicle, a different model may be required.

Pros & Cons

Pros

• Very light compared with lead-acid alternatives, making installation and handling easier.
• Strong starting power with up to 600A MAX CCA suitable for many small engines.
• Built-in BMS adds protection against common battery faults and helps longevity.
• Fits common YTX14 equivalents and can be mounted in multiple positions for flexible installation.

Cons

• Requires a proper 14.6V lithium charger for best life and performance, which some owners may not already have.
• Capacity is 8Ah, so it may not be ideal for unusually high accessory loads without frequent recharging.

Our Verdict

The YTX14-BS lithium motorcycle battery is a strong value for riders who need a compact, lightweight replacement with high cranking ability. Its integrated BMS and multi-position mounting make it suitable for motorcycles, ATVs, scooters and personal watercraft where fit and weight matter; just be sure you can charge at the recommended 14.6V rate and accept an 8Ah capacity suited to starting rather than long accessory runtimes.

Frequently Asked Questions

Will this fit my YTX14 battery compartment?
It matches common YTX14 dimensions (5.9 x 3.4 x 5.7in) and fits when the installation space and polarity align with left-positive/right-negative terminals.

What charger should I use?
Use a 14.6V DC lithium battery charger at about 1-2A; this is the recommended charge speed to fully charge in roughly three hours.

Is it safe in cold weather?
The battery supports discharge down to about -32F and charge as low as -4F, and the BMS provides protection against over-discharge and overheating.
