TPE Lithium Motorcycle DLF5L-BS 12V 3Ah LiFePO4 Battery - Lightweight

In this review of the TPE Lithium Motorcycle DLF5L-BS battery, the bottom line is simple: it is a compact, lightweight 12.8V LiFePO4 starter ideally suited for small motorcycles, scooters, ATVs and jet skis where space is limited and reliable starting power is needed. The reviewer found the battery delivers strong cold cranking performance for its size, is easy to fit into tight battery bays, and replaces common models like YTX5L-BS and YTZ7S while offering the added benefit of lower environmental impact than lead-acid alternatives.

Key Features

• Versatile compatibility: Replaces several common 12V motorcycle battery models so it fits a wide range of motorcycles and scooters when dimensions and polarity match.
• Compact dimensions: At 4.44 in long, 2.75 in wide and 4.13 in high, it is easy to install in tight battery compartments without modification.
• Lightweight design: Weighing about 1.54 lb, it is much lighter than equivalent lead-acid batteries and makes handling and installation simpler.
• Reliable starting power: The 12.8V, 3 Ah pack provides a rated 300A cold cranking capability, giving confident starts on small-displacement engines and some larger starters reported by users.
• Eco-friendly chemistry: LiFePO4 chemistry avoids heavy metal contamination associated with lead-acid batteries and is a greener alternative for repeated replacements.
• Charger guidance: Designed to be recharged with a 12V 1A LiFePO4 charger to protect the pack and extend cycle life.

Who It's For

This battery is best for riders of scooters, small motorcycles, ATVs, UTVs and personal watercraft who need a direct, lightweight replacement for common models like YTX5L-BS or YTZ7S and who have limited installation space. It suits owners who prioritize easier handling, a long cycle life, and an environmentally friendlier battery chemistry.

Those who should look elsewhere include owners of lawn mowers (this model is not recommended for mower applications) and users who cannot match the exact physical dimensions, polarity or starting power of this pack. Also, people without a proper 12V 1A LiFePO4 charger should plan to acquire one to avoid damaging the battery.

Pros & Cons

Pros

• High perceived build quality and reliable starts reported by users for small bikes and even a 700cc start-up in one case.
• Very light and compact, making installation far easier than heavier lead-acid units.
• Good starting capacity for its size with a 300A cold cranking rating and 12.8V nominal voltage.
• Environmentally safer chemistry compared with traditional lead-acid batteries.

Cons

• Requires a dedicated 12V 1A LiFePO4 charger; using a charger with too high current can damage the battery.
• Not recommended for use in lawn mowers and only compatible when physical size and pole orientation match.
