<p>The reason choose LFP : <ul><li>LiFePO4 batteries have a very constant discharge voltage, until the cell is exhausted. This allows the cell to deliver virtually full power until it is discharged, and it can greatly simplify or even eliminate the need for voltage regulation circuitry.</li><li>The other advantages of the LifePO4 batteries including low toxicity, well-defined performance, long-term stability and etc.</li><li>Especially, the use of phosphates avoids cobalt's cost and environmental concerns, particularly concerns about cobalt entering the environment through improper disposal.</li></ul></p></br><p>Parameters: <ul><li><b>Nominal Voltage : </b>12V</li><li><b>Capacity : </b>4Ah</li><li><b>CCA :</b>155</li><li><b>Weight : </b>3.35lb</li><li><b>Size : </b>4.45*2.76*3.35 in</li><li><b>Discharge Temperature : </b>-22 degree F to 176 degree F</li><li><b>Charge Temperature : </b>-4 degree F to 158 degree F</li></ul></p><p><b>Application : </b>motorcycle, snowmobile,wheelchair.</p><p><b>Advantages : </b><ul><li>The charging efficiency is more than 3 times higher than that of the traditional battery, but the weight is only 1/3 of the traditional battery. </li><li>The output voltage is more stable.</li><li>The working intensity of the automobile motor is effectively reduced.</li><li>The fuel consumption of the automobile is reduced.</li><li>The brightness of the automobile lamp is enhanced.</li><li>The sound quality is improved. </ul></p><p><b>Package included : </b>ONLY 1 x 12V 4L-BS LiFePO4 motorcycle battery</p>
