#10

10. KEMIMOTO Lithium YTX14-BS

• Dimensions: 3.6"D x 5.9"W x 3.4"H
• Weight: 2.2 lb
• Voltage: 12 V

Best for: Compact lithium with charge display.

Why it ranks #10: This 2.2-pound, 6Ah lithium battery lists motorcycle compatibility, but fitment exclusions and the need for a lithium charger narrow its use.

A built-in power display lets the KEMIMOTO LiFePO4 battery show charge status, while its pre-charged state supports initial vehicle startup without first connecting a charger. The 480A CCA specification and 2.2-pound weight make this a compact lithium option, with five universal-fit EVA spacers for adapting its fit in supported applications.

The case measures 5.9 by 3.6 by 3.4 inches, and adjustable spacers help accommodate different battery compartments; the listing still cautions that this 6Ah model does not fit several named motorcycles. Threaded-lug posts eliminate the need for nuts during installation, and pure copper terminals support conductivity. Pre-charged status is useful for startup, but a lithium-compatible 14.6V LiFePO4 charger is required for full charging. Older-than-1994 motorcycles may also need a compatible regulator-rectifier.

Skip it if you need a 6Ah battery for a listed excluded motorcycle; this KEMIMOTO model names CRF250L and CBR600RR among non-fits.

This suits a rider seeking a light lithium battery with a charge display and adaptable spacers, provided the vehicle is compatible. Check the listed exclusions and charging requirements; motorcycles produced before 1994 may require a lithium-compatible regulator-rectifier.
