Wokyy Vision Lithium Battery YTX4L-BS / YTX5L-BS Review
The Wokyy Vision battery uses LiFePO4 chemistry to deliver stable 12.8V output with 300 CCA, enabling quick starts in varied temperatures. It is designed as a drop-in replacement for YTX4L-BS and YTX5L-BS and ships with universal EVA spacers to aid fitment in many battery trays. The unit is lightweight—roughly 70% lighter than lead-acid—and maintenance-free, eliminating water additions and leak risks. Its high-power output helps crank motorcycles, ATVs, jet skis, UTVs, and snowmobiles even when stored for long periods. Check the compatibility against your original battery model before purchasing to ensure a secure fit.
Key considerations include the balance of weight savings versus pack size, and ensuring your bike’s tray can accommodate the universal spacers. The LiFePO4 chemistry offers improved safety, reduced sulfation risk, and consistent voltage during starts, though chargers and systems should be compatible with LiFePO4 charging profiles.
Forgetyo YTX4L-BS Lithium Battery — Compact Power
The Forgetyo YTX4L-BS is a UL 2271 certified 12.8V, 2.5Ah lithium battery with a maximum CCA of 250A. It weighs about 0.99 pounds and operates across a broad temperature range. The design emphasizes a direct lead-acid replacement experience, including being fully charged and ready to install. It is noted for its lightweight performance, faster startup capabilities, and extended service life compared with lead-acid equivalents. The device supports a wide array of replacement models and emphasizes ease of installation without activation or water maintenance.
Purchase considerations include confirming exact fit for your model and ensuring the bike’s electrical system supports LiFePO4 charging. While offering substantial weight reduction and startup power, some riders may need to verify the battery’s dimensions match their tray and terminal orientation matches their bike’s wiring harness.
Forgetyo YTX14-BS Lithium Battery — High-Current 8Ah Model
This high-capacity YTX14-BS unit delivers 600A CCA with 8Ah capacity, suitable for motorcycles, ATVs, UTVs, PWCs, jet skis, and snowmobiles. It is designed to be a rugged, all-terrain option with a relatively compact footprint and left-positive, right-negative terminal orientation. It can power extended rides and rough terrain due to strong starting power and improved energy density relative to lead-acid packs. Its compatibility list is broad, but users should confirm installation space and pole alignment before purchase.
Considerations include the need for a larger physical footprint than smaller 4L batteries, ensuring the tray’s dimensions accommodate the 5.9 x 3.4 x 5.7 inch form, and verifying the positive/negative polarity matches the bike’s setup. The LiFePO4 chemistry provides long cycle life and stable performance in a variety of weather conditions.
Ingeosolly YTX5L-BS LiFePO4 Battery — 3.5Ah, 250CCA
The Ingeosolly YTX5L-BS offers 250CCA and a 3.5Ah capacity in a compact LiFePO4 package. It is positioned as a direct replacement for similar lead-acid batteries in motorcycles, ATVs, UTVs, snowmobiles, and other powersports. The battery is designed to deliver reliable starts in cold conditions and is touted for its long service life and maintenance-free operation. It emphasizes a lighter weight than lead-acid options and compatibility with a wide range of models, though riders should verify the exact fit and polarity to avoid mismatches.
Key decisions when evaluating this option include the balance between capacity and physical size, the vehicle’s charging system compatibility, and how the 3.5Ah rating translates to starting performance for your specific engine displacement and use case.
GRECELL LiFePO4 Battery — YTX4L-BS / YTX5L-BS, Built-In BMS
The GRECELL battery features a built-in Battery Management System (BMS) to protect against overcharging, over-discharging, short circuits, and thermal issues. It is designed for a 12V system with 3.5Ah capacity for the YTX4L-BS and YTX5L-BS configurations. The design emphasizes safety with a positive terminal on the right and robust longevity, capable of 100,000 starts and thousands of cycles. A note on compatibility is necessary: double-check the physical dimensions and terminal orientation to ensure a match with your machine. The product highlights its reliability in rugged riding conditions and its ease of installation without maintenance concerns.
Considerations include whether a device’s charging profile is LiFePO4-friendly and whether the BMS supports rapid charging while maintaining safety margins. The compact form factor and safety features make this a viable option for users prioritizing protection and longevity in a single package.
Autocessking YTX14-BS Lithium Battery — 500+ CCA, 5Ah
The Autocessking YTX14-BS offers 500 CCA and 5Ah capacity, designed for durability in a wide range of powersports from ATVs to jet skis.

Buying Guide: Key Purchase Considerations
- Compatibility and fit: Confirm the exact model support (YTX4L-BS, YTX5L-BS, YTX14-BS, etc.) and measure tray dimensions, including terminal orientation (Left vs Right Positive).
- Capacity and starting power: Higher CCA helps cold starts; balance CCA with capacity (Ah) to match riding style and climate. Larger capacity improves longevity but may require a bigger space.
- Voltage stability and chemistry: LiFePO4 provides stable 12.8V output and improved safety, with lower self-discharge and longer cycles than lead-acid. Ensure your charger and electrical system are LiFePO4-compatible.
- Weight and performance: Lithium batteries are significantly lighter, improving handling and vehicle dynamics. Consider how much weight saving matters for your setup.
- Durability and vibration resistance: Look for rugged construction and BMS protections (overcharge, overdischarge, short circuit, thermal protection) to endure off-road conditions.
- Maintenance and safety: Maintenance-free claims reduce upkeep concerns; confirm there is no need for water top-ups and that leakage risks are minimized.
- Safety certifications: UL 2271 certification and other safety standards indicate higher product safety; verify certifications relevant to your region and vehicle.
- Warranty and support: Review warranty terms and availability of customer support for compatibility questions or installation help.
In selecting a small lithium battery for motorcycles and other powersports, prioritize models offering clear compatibility with your bike, robust CCA figures for dependable cold starts, and reliable BMS protection for long-term durability. While all candidates provide weight reductions and maintenance advantages, the best choice depends on your specific machine, climate, and riding style.
